Hi Mark, The 120 rpm limit is set at the controller. A test with the re- programmed controller on the actual wheelchair motors gave me approx 300 rpm. Acceleration/deceleration, turn speed, torque, etc are also programmable and are usually set low, 30 to 50%. Setting these values at a higher level dramatically increases performance. Even if they were a bit slower, I would take control over speed and this could be overcome via a couple of gears. The wheelchair motors (right angle gear head motors) are destined for my next tank (actually they are already mounted in the frame) of an Italian Ariete MBT. Most controllers have several DRIVE settings that can be programmed. I have one controller that has four and it is programmed at 95% for Drive One (default), 75% for Drive Two, 50% for Drive Three, and 30% for Drive Four. I am toying with the idea of using one R/C channel to control this, although it seems a bit redundant. Once I figure out how to control the POTS directly, I may do away with the mechanical joystick control.
The Batteries are, I'm sure our UK friends will choke on this, http://www.allbatteries.co.uk/1001Piles/FicheProduit.aspx?site=1001&lang=ANG&page=DCCDAMP3718&blocReferrer=305102 SBS60 SLA that I picked up new, unused from a surplus place for $39.95 CDN each. I have run the Bulldog around for an entire day without flattening the batteries. Yes they do weight a lot (18 kg ea.) but there is nothing better than having lots of reserve. :-) The controller powers the M01 motors perfectly. Although right now, I have a set of electric brakes hooked up and mounted off to the side until I figure out how to trick the controller. I am thinking I may be able to replace them with a couple of additional 24v fans mounted over the motors. That way the those fans will only run when the motors are running.
