I am having problems with my mild BL powered nano. The heli acts like it is hitting LVC after only 30-45 seconds on a couple of fully charged battery's with only 4 or 5 cycles on them. The same thing happens on another battery that is a lot older almost immediately. This just started happening. The last thing I did on the nano was re-solder a broken tail motor wire. I checked all wires and solder joints and all look good or at least the same as before when it performed good.
BTW these are stock e-flite lipos 1s 3.7v 150mAh 25C. Anybody else have problems like this?
