Hi=20
I have a 20b and about to start building a plane that is designed for a
IO 360. It has been suggested to me that I should change to a 2 rotor to
save weight. I=E2=80=99ve gone through the archives but didn=E2=80=99t reall=
y find any
pro=E2=80=99 and con=E2=80=99s of 3 or 2 rotors other than the max power ava=
ilable.
The plane will be used almost exclusively for long X-country cruising
once the bugs are worked out and hours flown off. =20
If my estimated max power required due to VNE is around 200hp, is the
Renesis always the engine of choice or are there advantages to keeping
the 20b, accepting the weight penalty and letting the engine loaf along.
I originally presumed the 20b would be better for me especially when at
my gross weight of 2420 lbs. but now I am unsure, so to change now
rather than later would be easier.
Any help from anyone flying either engine, and points that governed your
engine of choice would be greatly appreciated.
=20
