I have always believed that if you build it light with wings along the size of
the Diehl wing skins, use a Jab 2200 or an 1835VW, you should be able to get
there. Remember if you build the engine, like the VW, you can set the max
cruise RPM. The only reason that I would not suggest the Corvair
For a sport-pilot compliant plane, it's not enough just to have the stall
speed. You also need a top speed of 120 knots (138 mph).
So with limitations like that, why would you WANT a Corvair engine? It's
about 50hp too much. (Maybe even a modern bored-and-stroked VW engines
would be too much). I
you are not an engineer and don't want to spend a ton of
time learning calculus and aerodynamic theory.

That's GROSS weight of the plane, not empty weight! I'm sure we all
know that, but somebody will call me out on it...

Well Brett I would suggest to you that it stalls at 49 mph. I can assure you no
one other than you will fly it to find out.

1.
Are you able to simply extend the wings to meet the
stall speed of 51 mph for a sport pilot?
Mark Langford briefly commented on this being an option in his EAA webinar,
