View Full Version : Skid into wall = rubbing outrunner?
04-25-2008, 04:41 AM
Well I was flying my trojan this afternoon and when I came into land the last flight I had a little bit of speed and I went into a low cynderblock wall at 5-10mph maybe? Not sure exactly...
Anywho I knew something was up, removed the cowl and saw that one of the legs on the motor mount was bent a little, I also noticed that the motor is very loud now, so with the cowl off I powered it up and after just a few seconds of running full throttle it was pretty warm/hot. Sounds like something is rubbing on the inside...Any ideas if it is worth a repair or what it is?
Very disappointed right now. Very hard lessons to be learned...:blah:

I would post a pic, but visually other than the motor mount things look fine. Although when I spin it I can see that the bell housing (dunno what it is really called) seems to be uneven but I was not sure if it was just how the mfg cut it.
Lol...yes. Step 1 at weapons school!

Well I have looked all over inside and out, I dont see anything actually rubbing magnets/coils....not sure what is wrong.
I can only describe it as making a very loud, high pitch whine when running.

it could be one of those 3 wires came kinda loose on the motor, when one of the magnets doesnt fire it makes bad noises, most of the time it just doesnt run or the esc.

Sounds like you may have bent the shaft, probably can be replaced if you really look thur this site you will find a topic about motor shaft replcing. Good luck

Hmm, that was the only thing I could think of as well... But do you think finding the right shaft and replacing it is WORTH the time and cash on a $50 brand new 960kV?

Naw, just buy a new one.

I bet if you contact HZ, they can sell you a new shaft and for only a few bucks.
Replacing a shaft is usually pretty easy, and a lot cheaper than throwing $50 at it.
But hey ... if you got an extra $50 laying around ... I'd still say fix the shaft and send the change to me!

Man, I have rounded off 4 allen heads trying to disassemble this thing! I need some seriously hard metal allens to get this thing apart.
