Hi all,
First sorry for not being able to do this in your language...
I sold my M346 to one of my friend after few succesful flying seasons. My advice might be out dated for someones opinnion... ignore if so
Mine was first M140 later M166 powered. I'd say P100 is not enough and P120 is'n fun. Y-pipe will loose some thrust into noise. It has lots of it! Trim issues discussed earlier is solvable by lifting engine and adding down trust. Throttle to elevator -mix is not the same thing IMHO... Twin engine will help here. I had issues with one engine since I was not able to lift it far enough my bottle fuel tank was above engine.
Short tail, forward CG, low thrust line compared to fuselage center and low pressure high velocity exit under tailerons means it will climb if trimmed half throttle.
I had Savox 1270 on taileron, 1258 on aileron and 1256 elsewere. Had absolutely no issues of too small torque. Taileron servo plywood plate was carbon reinforced on mine and had still some flex. 4mm carbon tubes as triangle braces solved that for good with minimal weight.
Bruno is real and good guy. Maybe he is in holidays. I contacted him by email via ccmodel. Spoke with him abaut my mods on Jetpower 2019 and got very good impression about him.
Your twin 70N sounds good to me. My Y-pipe got fractured propably by fatique cracks and mechanical resonance of center seam on groins on trousers. My engine bearers weren't glued. Just 4pc M3 bolts into fuselage formers. There is plenty of space behind main landing gear mechanism. Gear it self is bit tight into wheel well.
Hope this helps.
