hi i have a fantom kry motor annd its great on some tracks but on this one track it glitches like hell when on the main straight, no1 else seems to have this trouble at the track so i was wondering if it was the motor because i have tried a new motor and the problem goes away. I have jsut added 2 shotky diodes and some capacitors to the motor to see if this helps the issue.

Thanks

Did you already have capacitors on the motor?

Just try one or two capacitors, problem should be solved

Khm, three is the number of capacitors to have on the motor. One between pos and neg terminals, one between pos and can, one between neg and can. Schottky diode is not that important for noise reduction, it's more to protect the brake FETs in the ESC. Anyway, using one is a good idea.
Check also that your brush hoods are straight and brushes wear evenly on both sides. If they do not, this can cause extra arcing on the comm, this may result in radio noise.

You sure it isnt a PT you've got john? They dont come with caps as std but they are included in the original packaging. He has tried different crystals and it didnt help either, he was still going in more of a straight line than usual tho

Is there any glitching with a different motor in?

Just FYI, Fantom is going to start selling Orion V2 based motors at around the end of the month.
