prop for 40 fs
i found an old fs 40 surpass, i bought about 1990. pulled it apart, to put in new bearings and ring and cylinder, ect. i have a lanier .40 trainer (4.5-5 lb) for a niece that wants to learn to fly. is this enough engine? (i would have chosen the .52) what prop to start with? i like to use a low pitch, around 5" for good acceleration and climb. i was thinking either 11x5 or 12x5. keep it just @ 10k, like my os 70 fs? i figure if it will turn a 11x5 @ 10k+, then it should have plenty of power for this trainer w/13 ounce engine.
