Relativily new to all this, I managed to crash my Blade CX2. That crash broke the lower head, so I got an aluminium replacement and followed the instructions to replace the broken plastic part with a new aluminium one. Fine, all done. Blades also changed.
Now, I try to get it to lift off and it simpl;y spins its blades on the ground, trying hard to lift but without (it seems) the power to do so. It simply stays on the ground and spins its Blades.
What have I done and what should I do to get this heli airborne...
