hi everyone.
i just love the bh, got one flight indoor adapting to it, but really responsive. i didnt get the tail motor yet since it is seemingly fine. (knock on wood) . i did check that i've tightened the collar, and i know that the play in the servors are normal since i check out a new BCP and was exactly the same. very slopy. but for the price, i think it's pretty fair. but the helicopter still seems to be surging up and down sum times. this time, i'm not exactly sure it's radio interference. i might try the 9T main motor that came with the AEK, (still running the stock 10T on a 1050 lipo). i know it'll kill your motor faster but i figured what the heck, i'm never changing back to stock batt so the 10T would be useless, so i guess i'll just run it till it kills itself from ecessive current draw and then i'll change to the 9T. (escuse from laziness)[&:].

and also, i've got a problem i notice that occured after i got the bh. i figured that if i were to increase the pitch of the main blades to hover in a lower throttle setting, the rotor head would wobble, quite terribly actually. my main blades are tracked, spindle's ok, drive shaft bented alittle but was ok before changing to bh, both paddles are aligned, my flybar's good adn centered, adn i have only 1 head dampening shim on either side to eliminate lateral play. but once i increase the head speed, it seems fine.

any help on why the heli would surge up adn down sometimes with little or no throttle/collective imputs?

thx
