[QUOTE="Syphen, post: 40964, member: 8687"] So long as the materials and construction techniques are the same - I wouldn't have a problem using aftermarket props... But just like propellers for real aircraft, small changes ( +/- an inch of length on the blade or a +/- a degree of twist on the pitch) can have large changes to motor speed and effective torque. The engine on my plane requires a prop that is 72.5" to 74".. anything outside that range is bad. Extrapolate that 1.5" to the blade length on the 4.7" means a manufacturing tolerance of 0.1" could negatively impact blade performance. I'd be taking a set of verniers to any aftermarket prop and measuring them out to ensure they were identical in size to OEM props. [/QUOTE]
