Re: SSRs, relays, speed controls

Actually gents, I'd like to set up to use just one 
stick.  The further you push the right stick to the 
edges, the faster the tank will go in that 
direction.  Not sure how Joe has his code set up 
currently but in any event it wouldn't be that 
difficult to implement.  

You already have stick position in terms of 
pulsewidth and a linear equation translates that into 
duty cycle for the PWMs.
