This topic is of interest to me as I have been considering a RV7A with a Mazda rotary. The KR2S seems to be comparable (potentially from a performance basis) to what I am looking to build. i.e., 190 - 200 mph cruise capability, 1000sm range. Obviously, the KR is way cheaper to build... has anyone built one with the Mazda power plant @ (approx) 180(natural) - 220(turbo) HP? Thanks for your time. Formula4G
-----Original Message----- The thing that worries me about adding distance to the fuselage in front of the main spar when using a heavy engine like a Corvair is that if yours doesn't turn out like Mark Jones', you'd be screwed. If you leave that distance per the plans, or maybe only add an inch, and then save the rest or... ...two. The height of the panel is another consideration. It's not a simple matter, and may very well have a different answer for each builder...
