Engine test stand

[NAMBA860]

Anybody ever build an engine run/test stand and put like an airplane prop on the engine for a load? Pics of it would be great if anyone has ever done this.

No pictures, but years ago I did some testing of .21 engines with airplane props. If you search here you will find pics of Terry Keeley's ducted fan test stand and dyno. normal airplane props are not engineered for the RPM that we turn. There are pylon racing props but the selection is limited.

Marty Davis or John Ackerman built and used one. I think Norm Doerr has it now. If I remember it used boat engines with the collet in place and cable bent to 90 degrees so there was room for the pipes. The load props were a Kavan product I think.

Since you asked.

There's a photo in there somewhere of one Jim Allen made with an airplane prop.
