cogging at speed.

Postby 65BAJA » Thu Feb 18, 2016 11:20 am

I have a ROC412 1800KV and an RX8 gen1 ESC. At low throttle it is really smooth. At about 20% throttle I start to get intermittent ratcheting. It will rev up to full speed but you can still hear the ratcheting a little. It is the same with the sensor wire plugged in or unplugged. I'm running it on 4S and the timing on the ESC is set to #1. I just pulled the ESC out of my Tekno to put in another car. The ESC was working great in the Tekno so I'm 90% sure the problem I'm having is with the ROC. The ROC motor is out of an old SCX10 and was working good when I last used it but the rig has been sitting for the last 3 years.

I meant to add I looked at the lights on the ESC for the sensor checker. They are really hard to see but I think only two are lighting up. I was going to order a new PCB from Tower but they don't carry the TT2613. They only have the TT2513. Will that work?

No, you must use the correct PCB board.

Will the Pro4 5mm rotor work in the ROC412 can as a way to make a 5mm output ROC412?
