|
Looking for input on the pros and cons of replacing the Cuyuna on my
UltraStar with a 447 a friend will give me.
Pro: 5HP more (theoretically means 350 fpm better climb)
Reliabilty?
Con: have to make a new engine mount or adapter
need a new prop (what size?)
Rotax parts are more expensive
Comments?

Dana,
Is there much weight difference?

Same... both are 85#. The Rotax may be slightly lighter because the 85# doesn't include the Kolb redrive.

How is it that 2 teenagers in the back of an original Volkswagen Beetle, in a crowded drive-in theater, can reproduce, yet it takes 2 spotted owls 10,000 acres? [quote][b]
