This is for you Gary! I will post more pics when she is done.

I have some good news...sort of. I tried the Clark board again and lo and behold, she works! Well almost. I have it set up with left stick controlling forward, reverse and turret rotation. The right stick does barrel elevation and steering. The tank moves fine, steers fine and turret rotation is good, but I cannot get barrel elevation to work and no sound except cannon sound when I push the right stick down and turret rotation works as intended but no engine sound, no MG, no barrel elevation sound. Is this just a programming issue? Should I buy the Sony remote to sort it out? At least the damn tank moves under power....
