Estate sale find! Lot of RC airplane engines, propellers and parts. Some are Wasp, Thimble Drone, and others are not marked. Selling as found, as is, not tested. My knowledge is very limited on these. Do not know if they are complete or missing parts, have broken parts, or salvageable, or can only be used for parts. Some are pretty dirty, all have dirt and dust from storage. All in photos included.
