Default M.O.A. Question

I currently have an old school Clod Buster based MOA crawler. My problem is when pulling up to an object at low throttle one motor seems not to pull as hard as the other. My set up is a Novak Super Rooster esc with two Integy 55 turn motors. At first I thought it was the rear motor giving the trouble, but the front will also do it when backing up a object.

Is this an esc problem? Should I consider using a esc rated for dual motors? Is it a wiring issue? Or is this just the way it is?

Thanks for any help.

I just tried using a Castle Creation Sidewinder and got the same results...

Would I need to run two batteries or "Y" them from one? Also would I "Y" the two esc's into the second one receiver port for throttle?

Here's a wiring diagram.
I've never "Y" connected 2 esc's that might work IDK.

I guess the dumb question is what is causing the motors to do this? I know a lot of MOA crawlers out there use only one esc or even a dual motor esc like the Outcry or a E Maxx esc.

I feel as if I'm getting over my head on this project.

Ah! Now I'm getting somewhere! I found one post where a fella had basically the same set up with simalar problem and went to 3s power. Could this be something worth looking into?

Sorry for sooooo many questions, but my brain is racked.

I would think you'd still have clod stall with 3s battery.. just my 2 cents.

Yeah kinda makes sense, it's all about the load on the motors. I read the Clod stall articles and I think my next step and the cheapest will be to try a stagger the pinion gears, then I'll try staggering the motor turns for the front and rear. After that I guess I'll live with it.

Thank you for all your help today!

I've been in your shoes years ago. Ran the exact same motors, same speed control with nimh batteries and had a decent amount of clod stall. I now run 2 esc's with holmes hobby motors and a 3s lipo. The feeling I'm getting from you is you'd prefer to fix the problem as cost effectively as possible. While the ultimate fix is a double esc I ran my rig for years with a single and actually grew to like a bit of clod stall. A small amount of stall will let the front tires attempt to find traction before the rear end loops you out. My recommendation would be to upgrade your motors to holmes hobby motors. These will blow the integy's out of the water. You may also try running a 1 tooth smaller pinion gear on the rear motor.
