I have a NIB ROO I was going to install a piston engine in but have changed my mind.
Which turbine would you recommend for a turbine "virgin"?

I fly at 4,350 feet ASL.

Simjet 1200 Keeps the weight down.... But you can slap almost anything on this jet, and it will fly well

16 - 22lbs is the ideal match, 27lbs makes it a raped ape

Like someone already said in a nother post on that subject. This plane was made for the 11lbs trust Sophia...The New Kangaroo2 is lighter than the old one, so anything from 12 to 20 is ok. I think you get about 130-140mph with a 12lbs...Anything asbove 20 is overkill...But it's seem to be the new tendency to overkill everything ( sevos torque, engine trust ect...)
