justin, good to hear that you've solved your problem, yep... i had plenty of problems with a hh gyro before getting dd. and which prop did you get? i just found out that the black/curly prop will have too much inertia and won't hold good during sudden throttle decrease. might not really affect you, depends on where you are at the learnign stage. i think the square prop will give better result.
ps, don't you think that a t500 is WAY overkill for a blade cp though? i mean, it really need digital servo to really excel, but we have a esc that is slow and has low resolution. i don't know... it'd yeild way better result on a rex i think.
