I must agree with Steve.

For over two years, I have tried to develop a cheap two-channel reversible 
proportional
ESC for our hobby.  My hybrid relay controller is my simplest solution at 
$150 while
the custom H-bridge SSR controller in my Hetzer costs about $250 in parts.

I have also tried using elevon mixing built into my Hitec radio with two 
IFI Victor
single channel ESCs.  However 40A Victors cost $115 each and standard 
elevon mixing
in my radio only provides full speed in the corners of joystick travel.

If you absolutely feel the need to "do it yourself", I would be pleased to sell
pre-programmed chips and schematics from my board (no PCB, no connecters,
no relays, no SSRs, no servo wires) at cost.

Joe
