RCIGN,

My RC Club received three drones as a donation.

The one in the pictures is the largest.

The other two were smaller and about the same setup. Between the two of them, we have one ready to fly! We are having difficulty getting permission from AMA to flight test it. (insurance don't you know).

The Norton Rotary engine was turning a 24" prop. I don't know the pitch.

Do you know where I can find specs such as Displacement, Horsepower, Torque, RPM range, etc on the Sachs 5.8?
