Hi, RainMan

In my drawers, I have a Twin Esc for big boats ...

Throttle drives the two motors ... AND Ailerons drive the Left/right motors differential.

I know tanks have two Throttle levers ... but driving is much easier that Way !!!

Hardware will be a little "heavy" for your purpose ( 50 continuous Amps, 3000 Hz, relay reversing, and Fiber Optics coupling to power units ), but soft may be greatly re-usable.

A little notice ... listing is 1400 Basic lines ( but with the blank lines !!! ... so, let's say 700-800 PbP program lines ...)

For info, to be comfortable, you need Two Processors w/PWM ( twin sticks driving ??? ), OR one with 2 PWM outputs.

I used a 16F876 ... but less than half memory is necessary !!!
