The torque from the FP without the gearbox is less than 1Nm. With the gearbox, it's a whole lot more. The data for the FP with gearbox is wrong on that sheet, as pointed out by Dr. Joe earlier. Stall torque is the amount of torque provided when you are at 0 RPM. When you are at maximum RPM, you have 0 Nm of torque. There really is no "normal" torque... it depends on what speed the motor is going. I think there are power curves for the motors around here somewhere, which will tell you how much torque you get for a certain speed. If not, you can probably construct one yourself.
