Just a fluke i guess, when i'm workin on it at home, i get servo twitches everyonce in awhile. And when I fly, i'm usually across the street in a small field.
I tend to fly and hover really hi.. it gives me more time to recover from twitches and my own dumb user controlled errors. I had the same problem with a micro heli i use to own. It was alot worse cuz of it's small size. I'd have to blame it on residential electronics. I dont have this problem when in a big open field.

I practice on the sim by closing my eyes and full sticking in random directions. Open my eyes about 2 or 3 seconds later and recover from whatever orientation i'm in.

I just bought a deans antenna, i'll install it if it gets any worse.
