same thing happened to mine on 4th use. it sounds like gears are stripped. they seem to be very poor quality

i think it has a centrifugal clutch, only engages when you give it fuller throttle and then disengages when you use low throttle. joe

The engine has a centrifugal clutch, the prop will not spin until you rev the engine up

As someone else here alluded to, there is a shear pin inside the prop. Pull the cotter pin out and remove the prop. If the shear pin is missing or broken, then replace it and you should be good to go.

Hi there, as for the issue your described, here is the information need to confirm: 1. Before starting up the motor, pls slightly open the ventilation door, that is, move the door forward to ON with about 1/3.2. When formly start up the motor: Pls pull the pull-up rope, to make sure the rope is completely pulled to the end, pls do not pause in the middel. 3. Pls add oil according to correct proportion. #90 gasoline: engine oil=25:1 #93 gasoline: engine oil= 30:1 4. Do not start up the motor, pls rotate the prop with hand, 1) if you feel heavy, then it means the prop is good. If not work, pls check the clutch ( spring) 2) if you feel light, then it means the propeller tip is broken Hi there, as for the issue your described, here is the information need to confirm: 1.

You must tighten the bit up. While depressing the silver button, loosen (counter-clockwise) the collar that holds the collet that the bit slides into. Slide the bit into the collet, then (while still depressing the silver button) tighten the collar (clockwise), tight, against the collet. Release the silver button and start the motor. It should work fine now.

My machine is temporarily in storage so I can't inspect it to figure out what might be wrong with yours; I hope another person has a definitive answer. But offhand, it sounds like a problem with the wedge pin working loose (is the nut securely fastened, with a lock washer or a self-locking nut?) and/or with excessive play in the crank where the wedge pin seats (perhaps it has become rounded after several wedge pin replacements, and a loose wedge pin began the process of deterioration). I'd disassemble as much as you can and make sure that the crank's wedge pin seat has not become worn, perhaps rounded or otherwise damaged. I can't figure out any other possible causes for the problem, assuming it works for a while and then goes off again, and the intervals during which it works are becoming shorter.

I think the whole gear box is the problem here. Not sure replacing motor will fix your problem. eBay has similar motor with gear boxes try it.

Jerry,My only suggestion would be that if there is a pin missing, that is a factory error and you should have DJI or whatever store you bought it from replace the whole copter. Can you send me a picture of what you're talking about and I'll compare it to mine and see what I can come up with? I'm usually pretty good at figuring these things out.

As other replies below state, a thin flat head screwdriver or a small pocket knife, etc will work. I DO NOT recommend using your fingers. I learned this the hard way. I was attempting to pull off a propeller with my fingers and ripped the entire motor out, snapping the wires.

Also check the pins on the trailer cord/connector. Mine were old and tired. A little bending and scrapping with a small screwdriver made a more positive connection to the "box" and fixed the NC problem.

It only works in forward motion, try miving left stick up and should start rotation, if not you may need a motor, a local hobby shop or site like banggood may be of help

Could possibly be the motor but not positive. If it's less then a yr old, take it back to where you bought it. Home Depot replaced the whole thing when ours broke. If I remember right, we didn't have our receipt but they were able to get receipt info because we had bought it with our credit card. Hope this helps!

It was only a few weeks, and I couldn't figure out why sometimes I would plug it in and motor wouldn't start. Once I started taking apart the motor it rarely happens. Good luck

I had a similar issue with mine as well. I had to really squeeze the housing together to get the screw to start. Can't be anymore help than that

I had the same problem until I realized the pins set upside down from my old remote. it has been working fine ever since. Good luck.

The nose cone/spinner pops right off. I just grab it with two fingers and pull, allowing access to the nut holding the prop. If that doesn't work try a small standard driver to pry between the joint.
