This set of unique helicopter plans is exclusively provided by TinkerSource. We do not know where you can get them anywhere else. Originally drawn by Joel Levin.
Plans to build the SJH-Osprey, a single-person ultralight helicopter.
Airframe construction calls for steel tubing or aircraft aluminum. Complete dimensions/details are provided for building the airframe.
This helicopter is powered by two rotor-tip jet engines. Plans show overview construction details for ramjet and pulsejet powerplants.
These blueprints as a whole are more of an overview, but provide good and useful information for the construction of a homebuilt ultralight helicopter.
