Any torque motor using neodymium magnets will have all the speed you could ever need. And they have better trigger response, which is always sweet.

I'll add something:

To prevent pre-engagement, the motor has little to do with it. It is still possible to get pre-engagement with a torque motor. You don't want the motor to turn slow, you want to piston to come back into ready position as fast as he can.

One step is to lighten the piston assembly. The lonex red piston is already heavy by itself, with the bearings it's worse. If you have a bearing spring guide, feel free to remove them from the piston assembly, as they are not needed (they don't hurt, too. But they add weight).

Now, I don't say you *will* get premature engagement with a 7.4v battery and standard gears. What I'm saying is that it could happen with a strong motor, even a "torque" one.
