Mine was a Top Flite P-51 that I did in 1973. Had flaps Goldberg retracts and a K&B .61. Flew great and I got many flights out of that airplane. Actually my first would have been my first RC airplane a Goldberg Cessna 182 that I built in 1971. My first radio was a Hobby Shack Cirrus 6 channel that was World Engines Blue Max that they built for Hobby Shack. I can't count the scale airplanes I have built since then but most of my airplanes have been scale. I was the same way when I built FF airplanes when I was a kid. It always had to look like the real thing. Don
