front/rear speed differences on dual esc setup

[matoch]

I have this feeling this is a common question but I can't seem to find the right words to search for a thread with the solution.

I have a crawler with dual esc's. When I hit the throttle going forward the rear tires kick in before the from tires. When I hit the throttle in refuse the from tires kick in before the rear.

The rear motor has the channel set as reversed in the radio so the motors turn the wheels in the same direction.

What am I missing in trying to troubleshoot this issue?

Thank you

James

You need to set a bias between them using your TX. I use a 4PLS and I set one switch to change speeds.
First thought, are both your esc calibrated the same ?

I was thinking its something else because the issue inverts in reverse. I suppose that could just mean that one or both think the trigger is in a different position.

I'll double check calibration after my kids go to bed.

Motor timing.

I'm not sure if this is what you meant by motor timing but the setting that force a delay before allowing reverse was enabled. Seems to be working now.

Thanks for the responses.

What ESC's, what motors, & what channels are they connected to & how?
Y-harness, CH2 & 3 or 4 with mixing, Y with servo reverser on one lead?
And what chassis?
More info please.
