I pride myself on my maintenance schedule I think I do the right things check the right parts etc. Infact I went over all my helis after last weekend with a fine tooth comb checking every nut bolt and screw.....Except.
I ovbiously missed one.
Yesterday best day of the year (now got panda eyes incidently) first flight with the knight 3D. just doing some warm up stuff pulling out of and verted hover when all of a sudden at about 100feet up I lose control totally the thing starts to roll and flip im pulling the stick one way then the other, thinking this is one hell of a glitch(strange in itelf on spektrum). She was falling fast so I knew the inevetable and flicked on the throttle hold, and continued to battle it all the way to the deck.
got it back to the bench took off the canopy what did I find. Well there may have been a chance I wasn't as thourough as I thought I was. The aileron servo horn was not on the servo, after some checking I confirmed nothing had broken so obviously the screw came out and the horn popped off. So a word of warning these are 9255 servos metal gears your not supposed to use threadlock on them so check them carfully.
The damage, I got away REALLY lightly. on first inspection it looks like undercarrage, feathering spindle, mainshaft and a couple of creases in the canopy, which is still usable. not had a chance to check it over completely but the blades are fine as it the flybar.
So guys maintenance maintenance maintenance....good flying
