Thanks for the replies. Now I know there is not a Glow engine that has the torque capabilities of my 100 watt (much less than 1 HP) electric motor which develops 560 OZ-IN of torque when stalled (0 RPM) at the SHAFT (no gearing). I already know the formulas for horsepower and torque, but hey thanks anyways downunder as its always a good deed to help out a forum member.
