I'll add my two cents to the subject. I plan built this one about 3 years ago with retracts and a K&B .61 for power. Only mod was adding about 4" to the nose to get the nose gear to fit. All other parts were built to the original plans. I built the original kit about 40 years ago and powered it with a Fox .36 believe it or not. The kit was covered with olive drab coverite with the kit decals. The plan built one was covered with silk and dope with Klass Kote two part epoxy for the finish. I still have the plans and may put one of these together again. I lost one to battery failure and the other to high power lines that sucked the model in when the radios were AM sets. Both flew great. If I build again I would forgo the bellcranks for the ailerons and go to servo per aileron. I couldn't get the bounce out of the ailerons on either ship when it was on takeoff run. One other thing I would do is reshape the fuse to a rounder shape aft and at the cockpit sides. Have the real thing about 1 hour from home at the Palm Springs Air Museum. Saw it do a run up and mag test on the 16th of Dec. for a flying demo on Sat. Quite a bird and quite rare! Resto looking good!
