Phi486

Hi Bob,
From what you said, I don't know until I try all the combinations ( rpm, prop-size, fuel,...) to find out whether my engine is within a bad catagory. Well, I will surely give it a shot once the Patriot is done. In another subject, is it necessary to use a high torque servo instead of the standard one? the specification calls for standard servos, but the picture on the box shows 4 high-torque units. I am a bit confused here? Do you know anyone has flown this Patriot with standard servos?
