So my sportsman has been acting weird lately. Its got a nasty motor glitch when it starts to get into a bind, even as I start up my vert board it'll get a bit jumpy.

Specs:

Integy 35t
Sidewinder
TQ3 & mini reciever
3s lipo

Any ideas?

sounds like you need to cut your comm and change your brushes

Check the RX antenna. Placement, broken wire, touching the chassis, etc. I had a similar glitch and after testing everything else, finally figured out it was the antenna. Hey why not check it, take but a minute or two.

Edit, RM might be right. I had other symptoms like servo glitch accompanied by motor glitch. But I'm guessing he might be right, check the motor and replace the brushes if needed. Comm cut isnt necessary to fix a glitch. Will make the motor run better though.

Just cut the comm, no change. Still using the old brushes, though there is still plenty of meat left on them. They may need a little freshening up though...

Well I pulled the motor apart and found one brush wearing waaaaay cock-eyed and my newly turned comm burnt pretty badly.

I put together another motor and my glitch has nearly gone. Still gets a little crazy every once in a while though...

That's most likely from the AM radio ;)

Probably so. I've got this one rock on my pile that drives the truck crazy. As soon as I get up on it, I never know what will happen. Weird.

There used to be, but it was frying servos, so its going to be making a trip to be repaired.
