HI
Bob, FWIW, I'd have a NA 3rotor and really work on tuning the intake and exhaust
to make it really go! If high altitude is an objective then add a single
stage turbo and forget the difficulty of getting the induction system just
right...
Regards,

on two.)
I am still on the fence, but would like to decide
what engine to use. I am building a Large wing Velocity, not the
XL. One of the original designers of that version of the plane
recommends that an io-540 250 horse would be the ideal engine. Now
I was thinking of either a 2 rotor that would be turboed to 200+ hp at sl not
at 10K or a NA 3 rotor.
I would like to get a consensus of the
better way to go? Suggestions? If I have to, I could
probably hang the exhaust out the cowl, or modify the cowl so as to get some
airflow over the exhaust to help cool it.
Bob
