OK...I'll bite with my first post. I ordered the Kitfox Super 7 from John at Sebring last month and look forward to June Shipping. I live 1/2 hour south of Viking and see them as a strong competitor for the engine choice. Obviously, the ROTAX is proven...However, there are similarities. Both use geared reduction PSRU's. Both have high RPM and piston speeds. I'm an instrumentation type so not a power guy...However, I've been reading a lot on the L15A engineering. Internals as good or better than Rotax for sure. A replacement "new" crate engine from Honda racing @ $2500. So here's the rub...unproven experimental or proven high cost. The RCM curve suggests that the 912ULS suffers failure in the first 50 hours like any such complicated system. Frankly, to early to decide...but I am intrigued with the thought of substancially returning affordability into GA.

I haven't spent time at Viking but will go up to X50 soon to check out his operation...I too have a slew of questions...but hopefull!
