Tony Nijhuis Posted March 5, 2018 Share Posted March 5, 2018 Well the recent cold weather has had it advantages and three snow day confined to the workshop has meant a couple of new designs have materialised. I had a discussion with David Ashby just before Christmas on the subject of free plans for the 2018 RCM&E special. So rather than the usual mid-size scale model you have all come to expect, David suggested why not a couple of simple jets, design to be small and cheap but more importantly FUN...... Now 10 years ago I did do a couple of jet Dog Fight Doubles in the form of a EE Lightning & MiG 25. Both were pusher prop powered and were well received....however, I did get a lot of requests at the time asking if these could be converted to EDF.....the answer was...not really because EDF had not really developed to a stage where a cheap workable installation could be found......roll on 10 years and the answer is definitely yes. Comparing an EDF scale design against a prop driven version of the same design, i would lay money the EDF version would be 10 time more popular to the modelling public, simply because its closer and reflects the real full-size aircraft so I reckon these are going to be pretty popular, plus its getting back to grass roots aeromodelling.... So back to mini jets....both are simple all balsa construction with 6mm balsa sheet. 24" Span, AUW 15oz, 3-function radio..... Test flew them Sunday in poor weather and what a blast!!!! being EDF and lightweight, really easy to self hand launch even with frozen hands....no nasty torque steer.. The fan set-up- AEO 50mm 3S unit, 30amp ESC, 1500mah 3S Lipo....all this from HK for around the £40 mark.... Quote Link to comment Share on other sites More sharing options...

Tony Nijhuis Posted March 6, 2018 Author Share Posted March 6, 2018 yes around the October time....unlike me to start the Special design this early....more time to enjoy I guess Quote Link to comment Share on other sites More sharing options...
Tony Nijhuis Posted July 2, 2018 Author Share Posted July 2, 2018 All done a tested ready for the Autumn Special...these little jets are so much fun....AUW is 15oz..... Quote Link to comment Share on other sites More sharing options...
Callsign Tarnish Posted July 2, 2018 Share Posted July 2, 2018 Are those cheater holes? Quote Link to comment Share on other sites More sharing options...
Tim C Posted July 3, 2018 Share Posted July 3, 2018 These look exceptionally good fun! It's great to see RCM&E getting some of its old mojo back, easy build sport scale models have always been popular builds Edited By Tim C on 03/07/2018 09:31:38 Quote Link to comment Share on other sites More sharing options...
Tony Nijhuis Posted July 3, 2018 Author Share Posted July 3, 2018 Yes they are cheat holes and are really necessary..Thinking about it you could put cheat holes in the top bottom of the fus to avoid ruining the side outline.... Hope these will be popular....really cheap install, simple to make and suppressing strong.. Quote Link to comment Share on other sites More sharing options...

Graham R Posted July 3, 2018 Share Posted July 3, 2018 Looking forward to getting the plan. They look a lot stronger than the small foamy jets with pointed noses that always seem to get well bent. Quote Link to comment Share on other sites More sharing options...

I would say its "chrome" profilm….. I've used it on a few models and its like a mirror. ken anderson...ne...1....profilm dept.

Tony Nijhuis Posted July 4, 2018 Author Share Posted July 4, 2018 Covering is chrome profilm and photos really well..... They are very strong little models...during early testing I cart wheeled both model without a scratch! the only significant damage was to the sabre nose when i dropped it nose first on to the workshop floor and put a nasty dent in the nose...top tip here for balsa models....if you soak the nose in a bucket of water for a hour or so and leave it to dry overnight, the wood swells and dent will disappear....then just get the hot iron on to the covering to smooth any creases. The fan is an AEO unit ADH300... packs around 13oz of thrust and is a very light at around 55g. The blade balance is not great and they resonate badly at low to mid speeds, but hey at mid to high speed which is where they are operating at for this model, they are ok....

Adrian Norris 1 Posted July 7, 2018 Share Posted July 7, 2018 Both were at the LMA show at Cosford today. They look impressive for cheap and simple easy builds (??) Quote Link to comment Share on other sites More sharing options...

Steven S Posted July 9, 2018 Share Posted July 9, 2018 This one has caught my fancy already, I hope there will be some build photos added to the thread or at least in Tony's album. I am wonering how the aileron linkage will be routed. I've already picked my paint scheme. 1 Quote Link to comment Share on other sites More sharing options...
Tim Hickey Posted July 10, 2018 Share Posted July 10, 2018 Hi Tony, Looking forward to seeing these jets in the magazine. I have two spare ADH300 64mm EDF units. Do you think these could be shoehorned into the models without too much modification or is 55mm the maximum size? Thanks. Quote Link to comment Share on other sites More sharing options...
Tony Nijhuis Posted July 10, 2018 Author Share Posted July 10, 2018 Tim, the 50mm Edf is shoehorned so no chance of getting a 64mm or a 55mm....the 50mm is cheap and works well.....or of course be my guest to enlarge the plan at the printers by 128% and the 64mm will fit.......the plan is a blank canvas so play around and have fun....that what the hobby is all about Quote Link to comment Share on other sites More sharing options...
Tim Hickey Posted July 11, 2018 Share Posted July 11, 2018 Thanks Tony. I will wait till the plans come out then decide to scale up or buy a 50mm fan unit. Cheers. Tim Quote Link to comment Share on other sites More sharing options...
