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.

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

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.

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. Edited By Henri Squier on 05/11/2015 21:10:55 Edited By Henri Squier on 05/11/2015 21:11:31
