OS Wankels
A .30 size True Rotary engine made for the R/C modeler.
Above are the newer model of the engines. Below is the earlier version of the engines. I have 2 of each which will be used to power the P-38 Lightning, B25 Mitchell, and the Douglas DC-3. Later they will also find a home occasionally on the B-17 flying Fortress. That should sound awesome. I guess I'll just have to swap them around and since they are small and compact, that should not be a problem
And here they are in a group!
