wierd motor problem
 

my pinion is not slipping on the shaft but the motor will rev up and nothing happens. could the shaft inside the motor be broken . this is wierd. it will go slow but I can hold the pinion gear an rev up the motor.
the set screw is on the flat and there is no signs of damage .

What motor are you using?

Sounds like a thrown shaft. That's when the shaft gets loose from the magnet.

If it's a Lehner, you might fix it yourself. Even if it's a Feigao it should be possible, but they are harder to open.

i just may go over to mikes house and show it to him. he has the jig to unscrew it and I can just do a "trade in" for a new one.
waiting to see if he is home and available. wow that sounded just wrong.LOL!

Wow, you live near Mike!? Please give him a handshake from me!

Some people have all the luck. Live by a fine gentleman as mike.

Yeah, be sure to say Hi for me please! be sure not to fall over his RC collection.. I bet you won't be able to put your foot anywhere in his hobby room..

it's is/was a basic XL2800

hey if you guys want something to do I would love an explaination of all these different motor part numbers.

I was running 14 cells cause 12 didn't do it for me .but maybe the motor was slipping

but compare with 12 cells top speed and torque and power band

Sounds like the magnet came loose from the shaft..

is the screwed on endbell loctited?
how is the shaft secured to the magent?
is this fixable?

yes is it fixable? mine did the same thing and i am very mad since i already have a problem with my 9920. mine will rev up to a certain rpm and them start moving slowly and them it somes alive but the motor is squeeking and hitting on something i think. mike, help PLEASE! can i send it to you for you to fix it?

well mike has my motor so ask him if he looked at it and if that one is fixable.

so is yours fixable?

I sdont know mike wasn't at the track today to ask.
