    OS Wankel 30's

    Bill,
    I have a project in mind to use (2) OS Wankel's in a scale airframe. The Type I (Gen II?) are pretty easy to find NIB at other sites. Can I use the OS "F" plug in the Gen II engines? I'll be using 10 x 5 props, looking for at least 11K on the ground. 25% Castor for the engines. I actually had a pair of the Gen II engines, but sold them (never having run them) because I could not find a source for the RE glow plugs. Will the "F" plug work for me in a Gen II Wankel? Many thanks!!

    Stephen

    You don't need a special "Wankel" plug for the O.S. .30 Wankel Type II. A type F plug will work nicely.

    Quick question, I just acquired 2 OS Wankel .30 engines and plan to crank them this week but in looking at the fuel system I do not find a nipple for pressurizing the fuel tank. Does this engine require a pressurized fuel system? In looking at the photos and the information I can find on line, these are the older type engines. Any information you have will be greatly appreciated.

    If you want to pressurize the fuel tank, you can tap the muffler.

    Back in the day, fuel systems did not use muffler pressure, just straight suction.

    I have read in a few places the type of fuel to use and the type of oil in the fuel. Do you have any suggestions? The local hobby show suggested I use the helicopter fuel because it contain more oil then the standard fuel I use.

    You can run regular fuel in the Wankel, with at leaset 18% oil content.
