Henri Squier Posted October 18, 2015 Share Posted October 18, 2015 Hi, For those who followed the mustang "homemade challenge" here is (at last) the balsa version. Initially intended to be semi scale, I discovered FPV and became (madly) addict. The project was thus re orientated to be a FPV platform. As usual for me : Sketchup drawing : The idea was to have an easy build, light and gentle flying plane : 43 inch wing span. Eppler 209 (discovered on TN Spitfire and work great). expect < 15 oz / sq inch. No scale details : straight forward build : close raw. henri Quote Link to comment Share on other sites More sharing options...

Henri Squier Posted November 5, 2015 Author Share Posted November 5, 2015 Hi, sorry for interruption ... Here some post sanding pics ... As it was previously said : just a rough P 51 like. Here will be located the lipo for Rx & servo and FPV gear (cam & Tx) : (foam braced with balsa and glass fiber / epoxy) I really love balsa I think it's why I can't buy ARTF (although they look so cool). The aim wil be to find a mate for FPV formation flying.

Trevor Rushton Posted November 5, 2015 Share Posted November 5, 2015 Henri I am very impressed with your build; it looks really good. I also like your drawing: is this the free sketch up or the full version? I have not mastered it but have been attempting to learn Turbocad 3D ; whilst I am getting to grips with work planes I do find the programme very feature rich but not very easy to use. I had given up on Sketch up but perhaps this was a bit premature. Anyway; good luck with the project. Trevor Quote Link to comment Share on other sites More sharing options...
Henri Squier Posted November 7, 2015 Author Share Posted November 7, 2015 Hi Trevor, thanks for comment. Yes it's the basic free Shekchup. For only plan drawing like I use it, you got more than you need. I began with Jason Anderson tutorials quite easily (**LINK**). But I won't hide it's much more time consuming than pen&paper. Turbocad is surely more powerful and allows you (unlike Sketchup) to create files for laser cutting. It's (highly) time consuming but has an accuracy unreachable with only pen&paper ... The first project (that flew) had its wing (made too fast on the bench) a little twisted. Nothing more in the air that two clicks of trim but the mis aligned ailerons were too much for my self esteem. So, for my N°2 and N°3 I made a cradle. This would have been tricky with only pen&paper. Preforming of leading edge top sheeting dry fit What's incredible with CAD is the accuracy. Just a light sanding and everything fits perfectly at once, really incredible.

Henri Squier Posted November 11, 2015 Author Share Posted November 11, 2015 N°2 and N°3. Why N°2 and N°3 ? Because N°1 is ... ... is late N°1. I wanted to do exciting things like in youtube and told to me " why not fly through an old empty barn ? " Immersion worked so well I was "in the plane" and not in the field with headset forgetting all basic physics ... ... 5.8 Ghz waves decided to stay in the barn as soon the plane flew in : no more video. A pillar cut the right wing in two and the engine moved back half way into the nose. Why N°2 and N°3 ? Because what I do best is what I've already done previously. Who did not tell to himself : "If I had to do it again I would do it this way ! " For instance : - 2.0° wing incidence was too high. - "cockpit" was too light, needed to be reinforced - wing bearing has to be in ply and not balsa. - need more power (260 W was not enough punchy), an so on ... Finally decided to improve the fuse design : So, there will be some more balsa dust. Edited By Henri Squier on 11/11/2015 21:39:55 Quote Link to comment Share on other sites More sharing options...
Henri Squier Posted November 18, 2015 Author Share Posted November 18, 2015 News from N° 2 and N°3. This time it won't twist. If you can do one, you can do two. Background is previous engine (250 W) now it's 350 W : big loops should be Ok. Quote Link to comment Share on other sites More sharing options...

Henri Squier Posted December 13, 2015 Author Share Posted December 13, 2015 Waouh ..... 1.5 aerobatic project, A4b aV-2, incredible scale alu P51 .... The level of this topic has recently become seriously high !!! A little intimidating ... ... well just to humbly finish what I've started with I was not happy with the "hole" version : Began the wing tips : ... and fuse : First cross : Forgot a little space here : I can already see it in the air ...

Josip Vrandecic -Mes Posted December 19, 2015 Share Posted December 19, 2015 Dear Henri , I follow your work here and conclude that you can make everything you want...so... congrats.... Cheers Jo Quote Link to comment Share on other sites More sharing options...
Henri Squier Posted December 20, 2015 Author Share Posted December 20, 2015 Thank you, thank you Josip. Your support touches me. I'd like to share I'm very (very, very) enthusiast about that : Found (cheap) at Hobbyking. It's very light (much lighter than ORACOVER antique i used previously). It feels however strong enough. You can see the aluminum like effect - very nice. Not a fold !!! Much easier than Oracover Antic. It makes you want to do well. Up to me it gives incredible results. Very nice alu effect. Here comparison with Oracove Antic Silver : I'm very happy with this : quality an price (10 euros for 5 m !). I'll tell you next if it's paint friendly. henri Quote Link to comment Share on other sites More sharing options...
Henri Squier Posted December 23, 2015 Author Share Posted December 23, 2015 Good news : it IS paint friendly ! Standard spray can paint was used. Quote Link to comment Share on other sites More sharing options...
Henri Squier Posted January 3, 2016 Author Share Posted January 3, 2016 Wing attachment ... (always a little tricky... for me) First I make a loose "bolt-mount". A hole has previously been drilled (perpendicular to the down side of the wing). Everything centered. fed into the fuselage maintained in place with tape - To be at the right place is the only thing possible. Cradle glued on both sides And finally the bolt mount. Just in case it could interest some one, henri. Quote Link to comment Share on other sites More sharing options...
Henri Squier Posted January 5, 2016 Author Share Posted January 5, 2016 How I deal with very (hugely) off center holes ... This plug ... ... belonging to this wing ... Is suppose to come into a hole drilled in a fuse former. But it's always a little tricky and the first hole is never the good one... ... and the hole becomes a cave. So I do in a thin drilled ply witch is placed at the correct place ... ... remove the wing and put a chinese stick surrounded by bakery paper : And fill the hole (cave) with epoxy : You can see how I've been searching the right fit with my drilling machine. And after epoxy cure and sanding ... ... I finally have a tight hole at the right place. If some one have an easier way to do : I'll take it. Thanks for watching, henri.

Henri Squier Posted January 6, 2016 Author Share Posted January 6, 2016 Oh thank you so much John .... Did I tell you I like HobbyKing bright silver covering film ? Did I tell you I like it very much ? very very much ... the way it accept curves ... hugely ... and small curves ... massively Oh ! sorry I've already told you. Thanks for watching anyway, henri Quote Link to comment Share on other sites More sharing options...
Henri Squier Posted January 18, 2016 Author Share Posted January 18, 2016 Nose story inside air intake Exhaust Result is a little below to what was expected. Curves appeared to be much more difficult to cover mostly on hard glassed surface. Anyway, initial project was not meant to be scale.

Henri Squier Posted January 24, 2016 Author Share Posted January 24, 2016 Well ... feels the biggest part in behind. Up to me looks better than N°1. Things to do while waiting spring : electronics and (eventually) paint job. Thanks to all those who followed, henri Quote Link to comment Share on other sites More sharing options...
barry knight Posted August 30, 2016 Share Posted August 30, 2016 Thats looking good. I like the covering. I used alu tape on a p51 form FMS... it looked ace but look ages. Liking your build. Quote Link to comment Share on other sites More sharing options...
