So, my heli took a bit of a hard crash. It got caught in some wind and landed on a rock. I don't see any visible damage but the blades don't engage. You can spin them fine with your hand but they don't seem to be getting power. The other functions work. All functions on the right hand knob work and functions other than throttle work on the left hand knob.

I don't want to just replace parts but I'm not sure how to narrow down the problem.<br type="_moz" />

I once had a shorted tail motor do this after a crash try unplugging the tail motor and see if the main motor spins.

Thanks for the reply. I tried that but had no luck. I think it may be the main motor. I had no idea the parts were so cheap so I just went ahead and ordered a replacement, we'll see if that works.

So, I replaced the main motor but I still have the same problem. Should I replace the tail motor or does anyone have other ideas?<br type="_moz" />

Hard to trouble shoot from a distance...
Motors don't run ? is that it ? Or motor runs, but blades don't spin ?
If it's motor not running, could be damaged circuit in main board.
Let us know what you figure out.
Best,
