Alan,
If you like to kit bash the Balsa USA Enforcer makes an excellent sport flier for a 12-14# turbine. It is fast, very stable, and has no bad habits. Mine was clocked at 160 mph with a Ram 500. It weighs 12.5 lbs. dry and carries 64 oz. of fuel, which is good for a 7-8 minute flight with plenty of reserve.

I made a lot of modifications for the sake of appearance, provide room for fuel and equipment, and to strengthen the wing. You could go with a more stock appearing Enforcer and it would fly just as well.

Do an RCU search for "turbine enforcer" to see construction pictures of mine and a number of others.
