I would go for Jr 8411's on all the critical surfaces and double check the rudder linkage because flutter is a problem on some of these Jets. The one that flew at Florida Jets with the Artes JB50 turbine flew well but it just wasn't that stable kind of bumpy in flight. I have the same jet and was considering a turbine conversion until I saw it fly in Florida. Maybe yours will be better.[8D]
