The engines on my new project are two Wankel / Rotary engines on which I connected the crankshafts to form 1 dual rotor 0.60 Cu/In engine.
We started it for the first time yesterday and it ran beyond expectations! The sound isn't like anything I've ever heard before. Some of the bystanders compared it with the sound of an onroad motorcycle or a sportscar!
The throttle response is really "snappy" and it guzzles fuel like there's no tomorrow!
After some running in, I carefully tried to move the sled, but unfortunately, the clutch slipped, so I'll do some adjusting and try again next weekend.
