the original motors only flew well a few flights.
soon i wasn't able to lift over than 1 feet off the ground.
the heli also was unable to pirouette.
then i changed the motors and it solved THIS problem.
however, at this point I had already lost the stock battery and replaced the 4in1. it broke down because the heli crashed. I couldn't maneuver it properly because i had extremely weak motors and it caused the heli to hit the wall.
i also replaced the servos because the heli lost the radio signal, hit the ceiling and fried the second 4in1 unit.
i had to replace the 2nd 4in1 for a new one.
this heli has been a collection of problems since day one.
i replaced every bad part and now it flyes ok, but my batteries simply don't last what they should.
since i've already replaced every electronic component except the radio, i don't know what else i can do.
you never had any of those problems with your lama, right?
thanks.
