Got a shipment from eBay today, 2 Speed 900 clones. I know they cant match the torque or RPM but they're cheap and cheerful so im happy enough. I then dug up my old Drum Spinner chassis (or whats left of it) and tried a few things out. Im going with a bulkhead design similar to the original Drumroll. HDPE for bulkheads and armour. 1 Speed 900 per bulkhead/drive pod (1 drive motor, 1 120mm wheel, 1 Speed 900/Spinner Mechanism). I took a quick snapshot for you guys but its difficult to translate what im getting at, hope this will do for the moment.
