I said the SONEX is overweight, not me ;-))

I didn't mean you needn' a diet, though I could use one .....
again :-) 20 pounds in a plane designed for 18 HP makes a huge
difference.

I was thinking maybe your - Sonex - had a few "extras" that could be
shed?

Given the 200# FWF limit (less than I expected which shows my
ignorance of the Sonex) your options get fewer. Wish I could be of
more help.....................

I have a Revmaster (normal aspirated) in an slightly :-) overweight Sonex..
The plane hasn't flown yet. Some extra HP could help. The Conti would fit
weight-wise, but seems also underpowered for this application. The Conti
turns slower than the Revmaster, but my prop diameter is limited by ground
clearance...

You may be able to rework your Revmaster with a different stroker
crank for better thrust, Bob Hoover's made a believer of me on this as
well as using the right prop combination. Another option that has
greatly impressed me is the BMW 1150 or 1200 M/C engines set up with a
good redrive. These produce good performance numbers with a lot of
positive feedback. HP varies per engine and set up from 90 to
100-100+. One of these in a Sonex looks very appealing to me, but
again I expect that you can do a bit better with your Revmaster than
you expect.

Tundra tires will give you more ground/prop clearance (;o)

Isn't someone flying a Sonex with a Corvair?

yes, but then the aircraft is named a "Cleanex". From the cockpit forward
it's not a Sonex anymore.

Hmmm.. what would you call it if it had a Tempo engine?
