It has been a quiet Xmas period with no National events and little happening over the holiday period. I was getting a little concerned as to how I was going to fill this issue until things started to move very late in January. I waited until late Janu-ary to catch the Old Timer events at P&DARCS then Antho-ny Mott decided that the weather pattern in early February was right for another record attempt. This moved the publica-tion date even further but it’s now all done and you are finally receiving issue No. 44. Everything is now coming with a rush and as you can see in ‘Coming Events’ there is plenty of action over the next few months as clubs take advantage of the fine late summer and autumn weather. I welcome reports and photographs for these and other events over the next couple of months

ALAN TILL’S

FOKKER D.VII

Alan Till of the Grantham & District Model Aircraft Society in the UK was a long time friend of Gary Sunderland and sent these photo-graphs of his Fokker D.VII built from Gary’s 1/4 scale design pub-lished in Flying Scale Models magazine.

Alan’s model depicts the aircraft flown in WWI by Lothar von Richtho-fen, the brother of The Red Baron Manfred von Richthofen, and is powered by an Enya 240 V-twin four stroke engine. The lozenge cam-ouflage was masked and hand painted using Humbrol enamel.

BALLARAT

(Photographs by Graeme Gulbin)

The Ballarat competition was our last for 2016 and the weather bu-reau had predicted light winds. They were a bit wrong this time as the wind, while not as bad as for our last two competitions, were far from light. When I arrived I was pleasantly surprised at the number of fliers that were there, more kept coming after I arrived so we had a good turn up. The new Ballarat field was prepared beautifully with a large pit and take off circle mowed to perfection, unfortunately the farmer that kind-ly loans them the field won't let them mow any more than this because when flying is finished he puts his sheep back on there and the grass is their food. Our landing area was in long grass and the 1/2A models got lost if you didn't line up where it landed. The good thing was that the models didn't get damaged the not so good thing was — we didn't know if there were any snakes in there. The first event was 1/2A Texaco both I/C and electric and with six entries in I/C and ten in electric the total of sixteen was the most we have had in an event for a long time. In electric there was a very long fly-off of just under 30 mins. with a blast from the past, Danny Missen, winning his first comp for many years. Welcome back Danny, we hope to see more of you in the future. Time for lunch and the Ballarat boys in their usual manner put on a terrific spread. The next event was Texaco with ten entries in I/C but only one in electric. There was a bit of carnage as the wind was getting stronger and coming from all directions. Kevin Fryer's Cumulus came to grief on takeoff as the wind got under one wing causing it to ground loop and breaking off the nose while my Bomber was picked up by a sud-den gust and cart wheeled across the pits breaking the engine bear-ers. There were four in the fly-off with Rob Taylor victorious with his Airborne. This is the first Texaco event Rob has won since he lost all his models in a garage fire twelve months ago, good on you Rob, keep it up. Next event was Duration and more carnage, this time from radios that seemed to go off the air. Greg Jenkinson's model spiralled in from a great height and Kevin Fryer's McCoy powered Cumulus did not re-spond on takeoff, both of these models were wrecked. There were eight entries in I/C and three in electric. Our new/old member, Danny Missen, came first in electric with the late Graeme Sinclair's son Stu-art second. Gavin Dunn lost his model down wind but got it back later to place third. Pat Keely with his ever reliable Bomber took out I/C. This was the first competition held at the new Ballarat field and it got a big tick of approval from all that were present. It's a little further away from Ballarat than the Hadden field but you don't have to go through Ballarat, you just keep on the Western highway until the turn off. It is freeway nearly all the way so I don't think it takes any longer.

We would like to thank the Ballarat club for their hospitality and look forward to many more competitions at their field. Brian Laughton

WINGS

OVER

WEST WYALONG

We went to West Wyalong October 26 to 30 for the twice postponed NSW State Champs and the Wings Over West Wyalong gathering. Queensland had scheduled their Team Trial for October 31st and November 1st but we scarpered back to Melbourne on Sunday 30th so we could take in the ACO concert on Monday night. It turned out to be a good call because Sunday and Monday were un-flyable due to wind and the Trial didn’t happen. The concert was fabulous, Slava Grigoryan played the Rodrigo Concerto. Willy Weather had predicted wind up to 5m/s on Thursday but better on Friday. In the event Thursday was quite good temperature and wind strength-wise but the wind direction meant a lot of flights went into the adjacent property. Last time I was in there the field had a fairly benign wheat crop but this time there was canola. The canola was waist-high and the 10mm diameter stalks were more than a metre long and intertwined. It took a minute to push through 30m after which time you needed to rest before tackling the next 30m. I set a New-World-Record for a short-distance, relatively straightforward retrieve in the first round of 2h 30min. It was all walking time since I had a direc-tion signal from the model at the flight line. Unfortunately the flight went nearly across the field and I didn’t go in from the far side. Since the contest was nearly over after retrieving round 1, we retired to the house for a coffee (it’s really nice being able to do this). On Thursday evening during the BBQ at the Mayfair (Motel) there was some scurrilous discussion about whether the F1C guys would play in the predicted wind of the next morning or whether it would be better to delay and fly in the predicted calm of the afternoon. Malcolm actually asked about this during the afternoon but the beer had been flowing and there was no mood for contest planning. So early on Friday, the Motel-stayers arrived at the field to find a gaggle of flyers leaning into the wind and pondering on the benefits of starting at 13:00. The fore-cast for the afternoon was for reasonably light wind from a more fa-vourable direction. On re-convening at 13:00 a caravan of cars set out and explored several sides of the field before sensibly stopping in the middle. The wind was every which way but it was also quite light so few flights landed outside the field.

It was almost too calm for comfortable F1A towing and the variable direction kept the flyers on their toes. The warm afternoon did produce some huge thermals. I did 8mins in round 1 (4mins on DT) and 10mins in round 2 - which resulted in a walk through the oats - but not through the canola. Leigh flew Open Rubber which was held at the same time as F1A and F1C. She had to change the motor after each flight because the December ‘09 rubber that had been rejected for Wakefield use was breaking a lot of strands on quite moderate winds. That evening at the dinner BBQ Leigh mentioned that she only had one motor left and it was full of knots. Albert said he had some good open rubber motors so after dinner he called round and produced a large braided hank of rubber. We shared a Baileys and whisky with Albert while unravelling the motor and reducing it to the required 26 strands. Saturday morning was, as predicted, the best weather of the week-end. There were fly-offs for F1C and Open Rubber. In F1C, Gary Pope had a short run of just 3.6sec and stalled all the way down giv-ing F1C to Roy Summersby and in OR Jim Christie had an attempt followed by a short flight giving OR to Leigh Morgan. Information on Leigh’s model is in the December FFDU. It was a fine morning, tempt-ing to fly except for the mosquitos. Due to all the recent rain they had been around all the time but the wind of the previous days had kept them in check. On Saturday a random clap would score several. The Saturday lamb roast was up to the usual standard. All in all a pleasant long weekend apart from the mozzies and the canola. The field is looking larger and I understand it has grown a bit more since Sunday. In the past the outfield has been quite friendly for retrieval but this time with the fully-grown canola crop it certainly wasn’t. We proba-bly could have flown from a better location and avoided the crop but when the flight line was set up no-one realized just how difficult it would be.

Camping was popular with many and these are a few shots of tent city.

While the weekend was predominantly set up for free flight models there is plenty of space for other types to be flown and a number of r/c models were in attendance.

The New South Wales Scale Aircraft Society held its “Show and Tell” in December in conjunction with its Christmas party. The “Show and Tell” meeting is for NSWSAS members, and modellers who would like to join NSWSAS, to bring along current building projects and share ideas and techniques with a view to fostering scale modelling in NSW. They are held every 3 months at various venues around Sydney. This time Ian McInerney hosted and we had a first hand demonstra-tion of Ian’s laser cutting and his large, flat bed scanner for digitising large plans. Home made pizzas finished off the day.

SCALE CLASSIC

DOWNUNDER

(Report and photographs by Chris White)

The Invitational Scale Classic Downunder was held from the 26th to the 29th of November on the NSW state flying field at Cootamundra with twenty seven entries spread across the five competition categories as scale modellers came from far and wide to take advantage of competing in a scale contest. This event is the brain child of John and Cheryle Rolf from Marulan,NSW, who are no strangers to scale as John was the president (now retired) of the NSWSAS for ten years .

John and Cheryle ran contests together over those ten years so this event had all the hall marks of being a great event,and it was, with everthing being organised by John and Cheryle to perfection. The state field was in tip top condition with full food catering for the entire event and even the weather was good with light to moderate winds all weekend and mostly up the strip... as there are three to pick from! The event will now be held every year so book it into your calender.

Chris White placed first in Master with a Corby Starlet. An own design and scratch built the model is 2.18m wingspan, weighs 11.50kg and is powered by an OSFT300

four stroke engine. Covering is Sig Koverall finished with acrylic automotive paint.

Back in 1999 the opportunity arose to make use of indoor sports cen-tres as possible flying sites for small electric powered model aircraft and a few members of the Victorian Scale Association built scale r/c indoor models. These models used the smallest available electric motors, were powered by NiCad batteries and controlled by the small-est electronic gear that was on sale at the time. Model weights were up to 270g so a fairly large model was required to achieve the low wing loading needed for relatively slow flight. The heading picture shows my 1.2m Piper Cub and Anthony Mott’s Flying Flea, both mod-els were successful performers able to fly within the confines of a single basketball court. There are now many ARF indoor r/c models readily available with micro radio gear and high capacity LiPo batteries and our old models are well and truly redundant and long relegated to storage. This preamble leads to my recent acquisition of a kit for a small model of an SE5 which was bought for me by my son Gary, from China and sight unseen other than the promotional pictures on the web. It came by post as a small flat box containing a protective plastic tray in which were several sheets of laser cut 1mm balsa and plywood components, a propeller, carbon rods and some very small screws. The model is computer designed with all parts intended to interlock using a series of tabs and slots. The balsa and plywood are of excellent quality, light and well suited for the model. The instructions are a series of illustrat-ed pages on the web identifying the various parts and showing the sequence of assembly.

The packaging and a few of the balsa and ply remnants after the components

for the model were removed. The laser cutting was thin and clean and it only

required a few nips with the point of a No.11 blade to free each part.

Assembly of the basic fuselage structure. Everything fitted perfectly and a mix

of cyanoacrylate and balsa cement was used hold it together.

Assembly of the small parts required a delicate touch (not easy for me these

days). Note the extremely lightweight structure.

the motor and battery.

The completed 378mm wingspan SE5, EACHINE also produce a Sopwith Pup of

similar design and size.

The top wing mounted Lewis gun, gun sight and windscreen add a nice touch.

Engine compartment with dual electric motors geared to the propeller drive

shaft. The small LiPo battery sits behind the motor and provides useful nose

weight. The wheels are balsa with a small plastic hub as a bearing and an

O-ring for the tyre. The wheels are retained on the carbon axle with small pieces

of heat-shrink tubing

The quality, fit and detail of the SE5 kit led me to look back on the production style of some earlier model kits. Above is FROG kit for a Short Seamew from the 1960’s. The die-cutting is not too bad, better than many others, but the balsa selection is poor with little regard for the required strength of individual parts. A conventional plan is pro-vided and a fair degree of skill and experience would be required to produce a flyable aircraft.

Going back even further, this early 1950’s Central Aircraft kit for the “Heron” rubber powered model also has a plan but all of the parts are printed on balsa sheet and they have to be cut out by hand (usually with a razor blade in those days). The kit contained some bottles of cement and dope (both long evaporated away) but again the balsa quality is poor. The rough sawn balsa blank supplied for the single blade propeller would have required considerable skill in carving to the correct section. I still have to settle on the electronics for my SE5, and as I haven’t yet found a 2.4GHz micro receiver that will bind to my Hitec trans-mitter then it looks as though I might have to buy yet another trans-mitter. More news when it has flown.

“ASSASSIN” COMBAT at

Greensborough MAC

The Greensborough club held an impromptu late afternoon/night flying session and B-B-Q in early January and, as I needed more content for this issue of AMN, I went along to have a look at the day/night combat flying. Models used were EPP foam “Assassin” flying wings, electric powered and virtually indestructible. These models are sold as airframe kits by Crash Test Hobby, a US company with a website at http://www.crashtesthobby.com. The shipping cost for a single kit is dispro-portionately high but can be alleviated by buying a set of three kits and if you can get an even larger group of purchasers together they offer five kits at a negotiated price plus a free one in addition. The kit contains everything needed to complete the airframe and re-quires the additional purchase of a motor, propeller, ESC, receiver, battery and servos, plus LED strips if you want to do some night flying. The design is based around the cheap motors and electronics sold on hobby and toy websites and provides a lot of fun for minimal work. The Crash Test Hobby web site has several videos explaining the

assembly of the model together with videos of the model flying and crashing at high speed into a brick wall without significant damage. Our evening of combat demonstrated how tough this model can be as planes brought down in mid air collisions were quickly picked up, re-started, and returned to the fray. The only thing that kept them down was running out of power. I had a fly with Graeme Anderson’s (Mode 2) model and, despite not having flown for some twelve months or so, it was easy to come to grips with the aircraft. It flew well from a hand launch and I was at ease with the comforting thought that if anything went wrong then the damage would be minimal to nothing.

22 Australian Model News

Warm up flights on the helicopter flight area.

Four or five Assassins in the air together look like a kettle (look it up!) of vultures circling their prey. It was fast and furious flying with a lot of collisions and crashes

but the models suffered little or no damage. The reinforced EPP foam structure of the Assassin is remarkably resilient.

A short break to take stock and change batteries. Landing an “Assassin” on a small table with only one arrester strap proved a

challenge for all. This was close but “no cigar”.

HAMILTON

FUN FLY

The Hamilton Model Aircraft Club held their annual Fun Fly & Swap Meet over the weekend of 26th/27th November. Once again the Ballarat club was well represented in numbers alt-hough we didn’t come home with any flying awards. The competition was pretty high in that regard when you have models like Garry Ber-gen’s 1/3 scale Super Stearman powered by a 215cc five cylinder Moki radial and his P- 47 Thunderbolt powered by a 250cc Moki radi-al. The P- 47 is probably around ¼ scale given that the full size was a large aircraft – much bigger than say a Spitfire. I spoke to Garry who is from the Constellation club in South Australia and he said he is building a 42% scale WACO YMF-5 which is at least a couple of feet longer in wingspan than the Super Stearman and the top wing signifi-cantly higher. That will certainly be worth seeing fly. Glenn Orchard, from Mildura, was flying a large Marchetti powered by a twin cylinder petrol engine, might have been a DA120 or something around that size. He flew it many times over the weekend in a very scale like manner, performing manoeuvres suited to the aircraft type which, going by what I have read, must be fully aerobatic. Not know-ing much about the aircraft I did a Google search and found this infor-mation ….“The SIAI-Marchetti SF.260 is an Italian light aircraft mar-keted as an aerobatics and military trainer. It was designed by Stelio Frati, originally for Aviamilano, which flew the first prototype of it on July 15, 1964. Actual production was undertaken when SIAI Marchetti purchased the design soon thereafter and continued with this firm until the company was bought by Aermacchi in 1997. The military versions are popular with smaller air forces, that can also arm it for use in the close-support role.” Max Rowan, Glenn White and I headed down on Friday afternoon and went straight out to the field to see what was going on and drop the trailer off. We arrived around 4.00pm to find many modellers already camped on site, mostly the familiar faces we see each year. From BRMFC, Peter Weston and his son Jason together with their wives were caravanning. Paul Ruddle and Murri Anstis were tenting (separate tents!!!) and my old friend Norm Morrish from P&DARCS also camped there for the weekend in his caravan.

It didn’t take long for Glenn to find the bargain of the year in the swap tent ….. a 120 four stroke size Spitfire for $120. Saturday morning arrived and Max found that he had forgotten to bring the wing tubes for his Piper Cub, fortunately another Ballarat member in Fred Eggleston was coming down on Sunday so Max had his wife Judy drop them around to Fred’s place on Saturday. There was some great flying to watch particularly Garry Bergen’s P- 47. The sound of that 250cc five cylinder radial spinning the four blade propeller is awesome and it pulls the airframe around the sky at quite impressive speed. The presentations were made shortly after 2.00pm and Gavin Wallis was kind enough to forward the official list of winners.

Peter Hewson’s

Fokker F.VII/3bm

“Southern Cross”

Peter’s model has progressed since my last report nearly twelve months back and it now has wings, undercarriage and the begin-nings of the outer engine nacelles and motor mounts. There is still a lot of work to be done and, like most scale models, when it looks to be 90% complete the build is about halfway to com-pletion.

The wing with covered outer panels spans 3.6m and takes up a lot of space in

the workshop.

The starboard engine nacelle with the vertical undercarriage strut is welded

stainless steel sheet and tube.

a DLE 20 petrol engine and has a shaft extension to allow the dummy readial

engine to be fitted in the front.

The centre engine is a DLE 35 petrol engine.

The outer engine nacelles required careful alignment. The port engine with the 1/6 scale plastic Williams Bros. Wright Whirlwind J5

Peter’s model is starting to look like the real aircraft.

Roy Robertson

Trophy

at

P&DARCS

The weather bureau gave us a reasonable weather forecast for the long weekend of the 28th and 29th January, we had Antique glider scheduled for Saturday and Texaco and Duration for Sunday. Unfortunately the wind on Saturday went beyond our cut off point and it was agreed amongst the fliers to hold it over until Sunday. Sunday dawned very calm and stayed that way until mid afternoon, first event was Texaco with fourteen entries, the most for some time, and thanks to all you chaps that went to the trouble of getting there. The only casualty of the event was me as my Bomber lost contact about 2 min into the flight and spiralled in just outside the field. While I was looking for my model I looked up and saw so many models in the air that they looked like a flock of very large birds, I must say this was one of the best events we have had for years. During the fly-off there were many models almost landing before catching lift and up they would go again. At one stage I saw Steve Gullock, Col Collyer, Ian Robinson and Don Grant almost on the ground, I turned away for a moment then looked back only to see the four of them going up like elevators. Needless to say the flight times were enormous with first place scoring 41.55min and even fourth place came in at 34.20min. In almost dead calm conditions it was a perfect contest. Electric Texaco had only one entry, Gavin Dunn, and as well as winning this event he did the Good Samaritan thing and took Norm Campbell to Casey Hospital after Norm tried to tune his motor through a rotating prop. Lunch, I know I rave on about the great food we get at lunch time at the clubs we fly at but honestly everyone agreed that the ‘hamburgers with the lot’ that Peter Harris cooks at the P&DARCS canteen are the best ever, even better than my wife cooks and thats saying some thing. Duration ’had eleven entries and the wind was picking up speed. There were some mechanical casualties with Lyn Clifford and Don Grant's YS 63's both having trouble and with our star photographer,

Graeme Gulbin having radio trouble. The lift wasn't so kind to us in this event with only two getting into the fly-off. Kevin Fryer with his McCoy 60 powered Playboy came first and “Mr Catch a Thermal” Col Collyer was a close second 30 secs behind. Electric Duration saw two entries with Gavan Dunn coming first. By now it was 4:00 pm and rather windy, it was agreed amongst the fliers of Antique Glider not to go ahead with this event and so ended one of the best days weather wise and in member attendance for a very long time. To cap it all off the Roy Robertson Trophy overall was won by a relatively new chum to our form of the hobby in “Mr Catch a Thermal” Col Collyer, a very popular win and a well deserved result. Thank you all again for making the effort to come to this event, your attendance made this a very pleasant and memorable day out. Thanks also go to all the members of P&DARCS for putting on this day for us, particularly the chaps in the kitchen. I hope that our good attendance secures for us this very prestigious event for many more years. Brian Laughton

Colin Collyer’s “Spook” is an unusual design with its gull wing. Many designs

of the late thirties had odd features favoured by their designers.

The aerobatic flyers were there on Saturday morning for a vintage aerobatic event.

The proposed Vintage Glider event was blown away by the strong wind that

appeared in the early afternoon. Col Collyer’s large “Thermalist” would have

been a strong contender in the event..

The Stearman

Model 75

Stearman Aircraft Corporation was an aircraft manufactur-er in Wichita, Kansas. Although the company designed a range of other aircraft, it is most known for producing the Model 75, which is commonly known simply as the "Stearman" or "Boeing Stearman". The Stearman (Boeing) Model 75 is a biplane used as a military trainer aircraft, of which at least 10,626 were built in the United States during the 1930s and 1940s. Stearman Aircraft became a subsidiary of Boeing in 1934. Widely known as the Stearman, Boeing Stearman or Kaydet, it served as a primary trainer for the United States Army Air Forces, the United States Navy (as the NS & N2S), and with the Royal Canadian Air Force as the Kaydet through-out World War II. After the conflict was over, thousands of surplus aircraft were sold on the civilian market. In the imme-diate postwar years they became popular as crop dusters, sports planes, and for aerobatic and wing walking use in air shows. The Kaydet was a conventional biplane of rugged construc-tion with large, fixed tailwheel undercarriage, and accommo-dation for the student and instructor in open cockpits in tan-dem. The radial engine was usually un-cowled, although some Stearman operators choose to cowl the engine. After World War II, the thousands of primary trainer PT-17 Stearman planes were auctioned off to civilians and former pilots. A popular approved modification to increase the maxi-mum take-off weight and climb performance involved fitting a larger Pratt & Whitney R-985 Wasp Junior engine and a constant-speed propeller. A considerable number of Stearmans remain in flying condi-tion throughout the world, as the type remains a popular sport plane and warbird. Brett Reaby found these two beauti-fully restored aircraft at the Geelong aerodrome. They are not too far from Melbourne and offer the opportunity for Stear-man modellers to get valuable scale detail and a genuine colour scheme for their model.

ANTHONY MOTT’S

ELECTRIC POWERED

DURATION FLIGHT

After waiting three months for suitable weather conditions Anthony and his assisting team assembled at Greensborough MAC on Wednesday, February 1, 2017 for another attempt at the electric powered model World Duration Record. Tedium 7 had been carefully repaired following the dam-age from the previous unsuccessful attempt and was in A1 condition at the official weigh in with a total weight of 4,977g. After an uneventful take off and some initial trimming the team settled down for the long night flying session. The night turned out to be a bit colder than expected but it was relatively clear and the model lighting system was working well so we wrapped up and flew on into the following morning. At day break the model was still happily circling and, after passing the previous Australian record time, things were looking good for a new World record until Anthony decided to bring the model down from its rather high altitude. After reducing power and commencing the descent the model passed behind the roof of the pits shelter where we were sitting and in the following confusion we lost track of its whereabouts until a few remnants of the airframe were seen drifting slowly to the ground. After a search the model was found sitting in a tall tree on the east boundary of the field and was a total write-off. Timing ceased when the model flew out of sight after a flight time of 14hours 21 minutes and 35 seconds, only three hours short of the record and with potentially enough power still available to reach that target. Anthony, after ten years of significant effort and success, has now de-clared his duration flying to have reached its conclusion. We are all getting a little too old to sit out the long, dark and cold hours watching a model go round and round so congratulations to Anthony on his great effort over the years, for his skill and determination, and a final farewell to Tedium Nos.1 – 7.

6:18pm on Wednesday February 1st, assembled, weighed and ready to fly.

6:47pm Wednesday, the model lifts off and the undercarriage drops away.

6:25am Thursday, February 2nd and the team has survived the cold night.
