Default RE: CMP 120 Zero ARF Build thread

Neo G. Yes, Its the 72" version...or was anyway.
L16/Nisha. I'm pretty sure the CoG was ok...its probably further forward than i had it before its rebuild. It was a bit heavier but i think we're talking 80oz max with all the reapirs. When i got home and before i took it apart i turned the electronics all back on and tried all the servos. Everything moved as it should. I've watched the video back a dozen times and for the life of me i can't see what happened. I took off, climbed out , banked right and throttled back a bit. I kept the nose down and if anything just before it was in a slight dive so accelerating and then as i pulled to turn again it rolled in the right direction but just kept rolling and i remember fighting it all the way down but it felt like i had no radio conection. Its the same radio gear, servos and radio set up as before only the batteries have changed for new ones and the air press gauge. The only thing i can see from a visual inspection and you can see on the photos is that the right hand aileron was sitting at the side of the model on the floor so i'll having a closer look at that tonight. Seems strange that its come off. Other than that i am at a total loss and now nervous about my radio gear. I wish i could just find something positively wrong. I'm not totally ruling out a stall but the conditions were perfect and i would say it was flying fast enough not to be anywhere near a stall. (from past experience with the plane).
I think i'd just flicked the switch on the radio to raise the gear too as one is locked up but the other wasn't quite up when it landed/smashed itself to bits in a corn field. So i'll check that situation out in case it caused something to change, but again it hasn't changed since the last time it flew.
