This is an ARF kit. It is precovered and has most of the hardware necessary to complete the build. Requires minimum of 5 HD servos and a throttle/choke servo. Slots for dual gang aileron servos. I bought three kits, built one and it flies great. Since that time, I have gotten into full scale aircraft and don't get the time to do the hobby. I used a DLE 55, but a larger engine would give even better performance for 3D. Has a cavity under belly for a tuned pipe for noise control. I have a tuned pipe for it for $100. I have one to sell at this price. Add $14 for Paypal. Shipping starts at $100 through Greyhound. Price reduced due to one control arm missing/damaged but recommend replacing on stabilizer. Approx $15 for Dubro part. Get in time for Christmas!
