Airship differential steering troubles

Hi all,

I'm faced with a problem - some friends and I are building a semi-autonomous airship (only a little one) and I've been given the electronics and programming to do, but I'm having trouble getting the pwm commands to work properly.

I'm using a little joystick with 2 pots to control it, the y-direction one controls the overall speed and direction of both motors and the x-direction one puts a left/right bias on them to turn the thing.

Here's the bit of test code I've got with just the one pot being used

symbol zero2 = b2

I suppose this may be typical - I've spent a lot of time, probably too much time, pondering what I'm going to use. It's pretty clear that I've reached the "analysis paralysis" stage and can probably go on forever, so it's time to get a few things put together and take it from there.
