Yah...
Bad luck about your 'Bear, Stal.
I busted mine up big-time - 3 in a row - before I managed to get a decent fly out of it. Bit of CA here and there, and she was sweet. The engine mount is a bit of a bugger to repair if you've managed to shift it off the foam. Just use a small phillips screwy or other blunt shaft to carefully prise the cowl off the fuse. Be patient - work the tool carefully around the cowl, going in a bit deeper each time, until you've freed it from the fuze. When you put it back on again, just use a couple of carefully placed drops of CA around the rim right at the outer edge - so you can free the cowl again should you need to do so. It only has to stay in place and not let go when you seat the canopy piece by sliding it under the cowl and then back again to close it.
They're a pretty flighty lil Bird - go like stink out of your hand, and are fairly snappy on the controls, considering the relatively small control surfaces.
Set it up so that the ailerons are dead flush with the wing, and the elevators perhaps a tiny tad above the rear stabs (for a smidge of up-elevator).
Set your lo-rates to 60% throw, 10% Expo for the Aileron, and 85% throw, 10% Expo for the Elevator. Leave hi-rates to 100%, no expo (great for ultra-snappy moves when you're 3+ crashes high

)
Hang in there mate - you'll love this thing to death once you've had a couple of half-decent flights with it. It'll keep you on your toes...
