Hello everyone, we are a fairly new team and were wondering: for an early-season DR4B, is it easier to build/tune a 50RPM or a 66RPM because both seem like viable options for us, and we do not want to go any slower. We were hoping to just mount the motor onto the C-channel where the mech connects to the bot rather than on the mech itself. Also, we are using 35-hole (17.5in) C-Channels, can this be built stably or will it require a lot of tuning? Thanks!
