Tamiya gearbox motor upgrade?

Sorry about all the questions.

Hi, I want to upgrade this to 7.4v so that I can run it from lipo.

Preferably I would like a motor that snaps right  in. Has anyone upgraded theirs?

There is no need to upgrade the motors. Worry about the motor controller your using. Make sure it can handle 7.4V and is configured to only allow 3V to each motor.

Ok, thanks. Could you please recommend a speed controller?
Any basic motor controller will work. Even if the controller itself needs only 3V to 5V you can used a voltage regulator to give the controller what it needs. So start checking SParkfun for motor controllers. They should have many options.
