I recently had a light crash , manged to land the heli on its side without any damage to the heli overall, except now when I try to spool up slowly I can hear the a click and then it stops . Although if I spool up quickly it starts up with no problem at all and flies normally, but I'm worried that its a sign of something wrong with the motor and don't want it going out at any random moment.

Any ideas what the problem might be? It's the 430X brushless motor with a 12t pinnion

couple things come to mind:

1. A magnet might have dislodged in the motor. It clicks slow, but speed up and other noises drown it out. Is the power still the same?

2. Bearing in the head is damaged (the stock Align bearings are easily damaged, and may click audibly)

3. one-way clutch is slipping (probably not though)

4. There is a bit of damage to one or more main gear crash from the on-its-side "landing". the clicking would not go away as you spool up though.

I'd look at #2 first, then at #1, and check the main gear just because its so easy to do.

There are other possibilities like the tail drive system...

Never, ever, ever, ever give up.

kk sorry for the delayed response, been busy for a while, but i'm going to look into all those now. any of those in particular that would bring the engine to a halt while spooling up ?

I think I have the problem down to the esc. With a new motor I decided to start the motor without any load on it. however the second I put one click on to the throttle it simply sputters and stops spinning,however if I go up further on the throttle fast it spins like normal so I'm thinking that maybe it got some moisture in it or something in my last crash and got a bit fried ? or is there something else causing this that I don't know about . Other than the problem starting everything else works like normal.

I guess that rules out the motor damage. It could just be an ESC setting- the timing or pole count. What ESC? I'd just go through and re-program it- often that takes care of these little gremlins.
