Pictured here is the 9 cylinder radial engine with plans offered by Lee Hogdson of Ageless Engines. Take a look at Lee's extensive website (printed out, it is over 70 pages) and see this engine plus his 14 and 18 cylinder models and the Bentley BR-2.

Lee has spent over 3 years developing:
1) A constant acceleration cam lobe profile
2) Electronic ignition in conjunction with MJN
3) Improved piston rings w\ mineral oil break in,
4) Lastly, a full diameter impeller with a new seal plate to absolutely keep the oil and gas separate.

At last, it is time for the sleeve valve to take center stage. Lee has just added some new information to his web page regarding sleeve valves. Take a look.

Any builders of radial and/or rotary engines are welcome. And if you have an interest in full sized "round" engines, we would welcome you as well.

Please note: This group is NOT for the exchange of information regarding the Wankel type of rotary engine. By "rotary" we are referring to antique airplane engines where the engine engine case and cylinders all rotate about a fixed crankshaft. Do NOT write and tell me you "love" Wankel engines !!! :o)
