Hobbyzone/E-Flite Champ S+ Propeller Adapter Wrench


New member
The Hobbyzone® Champ S+ is a great little plane, but the propeller-adapter is a well-known weak point.
Removing and installing the adapter can be difficult because it is difficult to get a grip on the motor (recessed in the cowl).

This wrench is designed to slip in behind the propeller spinner and hold the motor while the screws are loosened or tightened.

I've included the STL file with the 3D model along with the original OpenSCAD source (just in case there's an OpenSCAD person who wants to modify it... :geek:).
