Put an encoder on both output shaft. Monitor the difference and balance them.

Don't hook-up in series and what happens?

Parallel-wiring. But that's what Burf said and you already gave him the best answer.

i just did that because it felt like this thread was dying out. if i feel so, I will change it to the righteous (winner?). hmm, the uploader isn't working for me....

You connect the motors to the same power-supply, witho... like this:

Is a dual H Bridge setup a parallel connection? specifically an l298hn chip.

Is there any trim adjustment, like on RC planes, to even up things electronically?

Wiring them parallel should at least help.

I'm using my gearbox for a light seeking robot, and I don't know how to wire it up in parallel in my case...

It's not the gear box it's the motors that are running at different speeds.

Unless there is a mechanical issues on the slow side the gear boxes will always produce the same output for a given input.

I guess the tank is intended to have 2 motors driving separate tracks so you can alter the speed of either motor for steering. You may well be using this incorrectly.

The first thing you should do is check for axle slippage or binding on the slow side.
Then, wire the motors in a parallel circuit. That way, they will try to maintain the same speed. When one motor gets more load than the other, it will draw more power to compensate without affecting the other.
