Evolution 1.00 vs OS 91 FX
Anyone have info on the Evolution 1.00 ? Particularly compared to the OS 91 FX ?
Curious about this engine, considering putting it on a Excelleron as a backup plane for Intermediate.
My primary plane is a Prophecy with a Webra 1.45 and Macs pipe, the Excelleron would be used over the winter while I am cleaning up the Prophecy after a season of use and abuse.
