Our high school team is currently building a competition robot with a 2 wheel direct drive system. We are currently using 2 castle mamba monster escs with 2200kv motors directly attached to each wheel. We can drive very fast which we don't need, driving slow causes the motors to stutter and driving is erratic. We need slow and precise movement, maybe 10-20mph max. Any help would be greatly appreciated as we are all new to this.
