I have had my Lama V3 for a couple of weeks now, and I was starting to get the hang it. But then about a week ago the lama stopped working. It wouldn't get off the floor, the rotor blades were spinning but the whole helicopter was just rotating on the floor.
So I bought two new motors and replaced the old ones, and the helicopter stopped spinning around but it still did not get into the air, it just stood on the ground with the rotor blades rotating. So yesterday I bought a new battery but that had no effect at all, so I still can't get my Lama into the air.

I was hoping someone here could help me figure out what might be wrong and which parts I may have to change.

Hoping for some brilliant answers
