I had my head stuck under the 182's instrument panel all day
trying to get four 3/8 nuts on the motor mount bolts.
On a 182 the nuts are inside a hat section longeron
with about a one inch by two inch access hole.

What a rats' nest of wiring under there. I swore
to myself when I get a homebuilt I am going to hinge 
the panel down at the bottom with a piano hinge so
I can work behind the panel.

I am leaning towards a Lancair 215/360 partially built.
I am thinking of a turbo compound rotary with an air to
water intercooler and a P51 style cooling duct with
the water to air part of the intercooler system in 
front of the radiator. I will use an electric pump
to circulate the separate coolant in the intercooler
system just like the RR Merlin in the P51 had.

The engine will be upright. I won't use a muffler
with the blow down turbine. I think I will
feed the power from the turbine into the PSRU
end of the engine before the PSRU and the centrifugal 
supercharger will be driven off the accessory end.
I will use fixed turbine and supercharger gearing 
and optimize it for 12,000 to 17,000 feet. 
I don't mind oxygen.

I have heard of potential flutter problems with the
Lancair. Is there anything else to watch out for?
