360 Hi-torque Motors in Modern Tanks (A Squad Video) you haven't mentioned it and for the $7.00 & that includes shipping sounds like the cheep way to go and get the tank running. instead of burning the rx 18 in this one out or spending money for a transmitter to use the clark board, that you still don't know if it can handle these motors either
