I built one for Vincent in Arizona who is on RCU. The areas that need tlc are the landing gear, gear doors, servos in the fin, top hatch and speed brakes. The rest of the build is fairly straight forward. Great looking jet. The composite arf kit does not include wing fences, so you will have to fabricate your own. I sent a set of templates to some guy in Ft Lauderdale, but never got so much as a thank you for my efforts.
