@caterpillarnut , Paul Knapp says he burns the lowest octane fuel on the market, namely Unleaded Gas. It burns faster than the high test stuff and the engine just loves it. He recommends it to all his engine builder friends. He ran out once and borrowed some high octane aviation gas and the engine ran terribly. He bought some unleaded and it ran great again.
The Bentley uses straight unleaded- no oil added. The engine has a pressure lube (total loss) oil system and uses straight Castor Oil.
@Alisterwolf66 The model engine works just like the full-size version using a simple block-tube carburetor eliminating the need for a blip switch. These simple carburetors required constant attention to minor fuel adjustments. During landings the pilot had his hands full trying to adjust fuel and air mixture while throttling down and side-slipping the aircraft to descend. Though most later model rotaries used carburetors many aircraft retained the blip switch for convenience and safety.
Not all rotaries needed blip switches, many later model rotaries had proper carburetion. One notable exception were the Gnome monosoupappe engines, which due to the way they were designed, were impossible to have real carburetors.
Nice video. Seeing Robert's plane fly with Paul's Bentley whirling away was really an experience. Add to that, Ray Williams also flew his Morane Saulnier L Parasol with the LeRhone replica whirling away made the day a historical event.
There is nothing like the chatter of a real rotary engine.

Its a Rotary not a radial, so it would have to be fuel injected I think, I don't think it has a carb. Amazing though ..

How about the ignition and carburetion? Does the model work like the genuine thing (blip switch, fractional ignition, mixture control, etc)?
Absolutely stunning craftsmanship! You have my utmost respect for this.
