I built my first with a ProWin, the later set-up is in a cheapo V3 shell.
The G&P has not trouble pulling a M130 with high speed gears, and I suspect that any high torque motor will be able to do the same. With my set-up and an M130 with an 11.1v battery, I suspect the rof would be around 22-25rps. I want to believe that I read that the Matrix 3000 Magnum motor is a rebranded Echo1 High Torque motor. I am not positive on that, but I have used 2 Matrix 3000 motor and I am a fan given their $45 price tag. I widh I had the time to compare my G&P M160 and Matrix motors to get some numbers on rof and amp draw.
My personal goal is 30+rps at near 400fps, so my solution has been to get the power and then up the voltage until it trips 30rps. I am still going to try different compression component combinations to try to keep with a PDI 170%(M120), but if I can't get the power I want I am going to up to a PDI 190%(M130). I know I could gain 2ish rps with a good MOSFET, but I am going to save that for last, $85 MOSFET is just not in the budget right now.
