Hi, I'm new to paddle tugs, can any one tell me if I can use the motors and gearboxs from the Heng Long model tanks??        Also whats the max rmp for the paddles    Mike.

Hello blue eyes.
first of all welcome to the P D's
if you look in the main menu on the left side ,you go to forum and look for drivesystems .
you'll find all you need to know (and lots more ).
the tank drive will work just fine all  you need is a tiny little bit of common sense
should you have anymore questions we'll be glad to help you out.
