A few more pictures of the screw drives
the drive mounted
just needed a small modification to the blade to get it to fit. I had to do a few mods to the servo aswell. The original mountings were chopped off and a 5mm hole drilled for the mounting pin to go through, the problem with this is the servos are so small with the pin through them there was no room for the electronics so the have been removed and will be fitted in the body of the dozer with just a wire running up to the motor in the servo .
