Thanks a lot! We totally stuck to the KISS principle this year and last. We didn't use drill motors anywhere on this bots, only CIM's. We get pretty good traction with the tread system (the metal grille fits nicley between the cogs). We haven't had too much of a problem keeping treads on, but we cut some of the flanges deeper just in case. We had some problems with the flange on the drive wheel coming off a lot, but that was nothing a little spot welding couldn't fix. I didn't order the cylinders, but I believe that they are 12" stroke and 1.5" or 1" bore (not sure though, another kid ordered the cylinders really early, before we even had an agreed on arm design. We just used what we had).
