I think the prop weight might be too high with a 96" prop on a Corvair.

I like that Corvair engine too, but I wonder if it can swing a 96 inch
prop. Many of the individuals who are excited about the 103 HP VW
engine are happy with it because of the amount of thrust it can produce
swinging a big prop. Of course, most people don't want and don't need a
prop that big, it causes the top end performance to suffer but for
certain applications, wow.. some of those aircraft really hop off the
ground:

The firewall forward package for this backyard flyer is a 2276cc VW
engine, 2.47:1 PSRU. I am still looking for the weight figures for this
engine.

I wouldn't be as keen towards what I am seeing about this engine if it
wasn't for the huge prop it can handle and my specific need for extreme
STOL without high speed performance. I have been collecting links to as
many extreme STOL aircraft as I can find and have listed them in the
links section of the following yahoo group:
http://groups.yahoo.com/group/Extreme_STOL - I am still undecided over
which aircraft to build but I want something which has a takeoff roll
of 100 feet or less which will handle a large adult with room for one
average sized passenger. The CH 701 is too small, the STOL King looks
good but so far I have not been able to find a second party (aside from
the guy selling plans) who has built it to confirm the claimed
performance.
