[>:] looking for some help. need to know why my lama v4 is losing power, meaning after 2 - 3 min. of flight time I cannot get my heli more than 6 - 12 in" off the ground. I have tried brand be lipos I bought from Deal Extreme and I get the same result. Are my motors bad or is it my 4 in 1 ? Also I have very slow rotation to the right but very fast to the left. overall this heli still hovers pretty good.
