Which is sort of why something like the SPA happened, some people just wanted to put a sport engine into a classic airframe with fixed gear and just fly it without the fiddling.
No pipes, no retracts, no problems

But some other people aren't happy with that??
My first powered plane was a Curare I built in 1990. It had a ASP .75, fixed gear and was fantastic for sport flying and I understand the desire to build something like that "properly" as I've thought about it many times over the years.
