Katana
I have the Creek Katana with a 3W24 for power.It's not quite unlimited,but it's not challenged either.It tumbles great,does a really nice flat spin as well as a great knife edge spin.I am running a 3W 18x8 wood prop for break in.I have an 18x8 carbon fiber waiting to go on.It should gain about 300 more rpm.This a great plane as far as I'm concerned.You just have to take your time in the setup.
