i got DD installed, no chance to fly more then 2 or 3 min b/c of extreme wind but even in that it seemed to be flying better...i couldn't get the stock tail to simply pull off with ca debonder, instead, i cut it, with wire cutters no less...o well it'll work, you can even tell now, i'm just gotta have to go find some heatshrink tubeing to make my solder joints nice and pretty. o and i have been expreienceing the same spining on hard throttle moves but hopefully the dd will change it at least slightly.
