Sorry your having soo much trouble.
I may not have an answer (I am new to helis).
I have noticed today when flying mine and use my older battieries from my planes a 1500ma it starts popping up and down at times. I am just learning to hover and its scary. Only seems to do it with the big battery.

DOES ANYONE WANT TO BUY MY PRO???????
Otherwise i am going to throw it in a dumpster. . . I think i am just having a bad beat with this one! I CAN NOT get my sticky collective (heli gains and looses 2-5 feet in altitude in a second or so, kinda bounces'ish and doesnt stop) to go away. This is what i have done:
Replaced. . .
MAIN BLADE GRIPS W/ SPINDEL
DAMPER RINGS AND WASHERS (ONE RING EACH SIDE)
CENTER HUB
MAIN SHAFT/DRIVE GEAR
BLADES (FLAT BOTTOM WOOD)
ROTOR HEAD ASSY (the flybar holder that slides on the center hub)
I have double checked all of the ball links and have worked hard to make sure they are smooth. There is no low freaq vibration, a little high freq from tail, but not much. I have also taken the extra flybar weights i added off. . . and the moved the stock ones half way in. . . I called horizon and they did not know, and then i asked God and he said to ask you guys
please help before it flys with brushless Evan power as my fist playing the part of the ESC. . . please?
Thanks guys!
