Scott: Based on what you say, there is only one engine that should be considered for aircraft applications, the Mazda 13B or 20. Assuming that a quality PSRU is placed on the only thing that can go wrong with the engine is failure of the apex seals. I had a 1972 Mazda that had the old failing apex seals. I was able drive the car 3000 miles with the seals failed. Initially, I wasn't sure that any thing was wrong, but I noticed that my gas mileage had dropped and my acceleration above 70 MPH decreased a bit.
I would love an engine with this kind of reliability, but the light weight VW engine is well tested and a no brainer for the KR2. I would certainly go the rotary way before I would put in the weight of a Franklin 150HP, which is significantly heavier than the rotary system with no power gain and less reliable. > I've decided, because this issue seems dear to so >many out there, to write a Aero Engine vs. Auto Engine Larry Severson Fountain Valley, CA 92708 (714) 968-9852 [email protected]
