Some of the plan has faded away, sorry about that.

Here is one that should interest some of you. Its the Berkeley Bootstraps A-RC, a 54 inch wingspan cabin RC/FF that would make a good RC trainer today. It was kitted by Berkeley in 1952 almost at the very beginning of the RC revolution. I remember it as a kit on the top shelf of the hobby shop where I worked part time in the mid-to-late 1950s. For those of you interested in what early RC entailed, just look at the plan at the rubber band powered magnetic escapements and the little one-channel 27mh receiver. No proportional servos then! No plug-in stuff either. Everything was pretty much soldered together. And the batteries were un-rechargeable dry cells. I personally had a transmitter and a 2-tube receiver (for the life of me I can't recall the brand of them right now) and used a Bonner escapement.

Nice looking plane. Sort of reminds me of a Sig Kadet ...

I drew mine up from the Flying aces article. I had it scanned and blown up to the scale I wanted at 83 inch span. The lines were way thick! I traced over them to get basic working drawings then winged it from there. Be carefull though as the drawings are not symetrical in some areas like tailplane rib spacing. I guess the short kit suppliers must have a proper plan too.

Hi Allen,

Thanks for the insight. I am really wrestling with selecting which old-timer I am going to build. Originally it was going to be a Playboy Sr. but now I am torn between that one and the Keil Kraft Falcon, the Cumulus and the Cobra. They are all beautiful designs and will all make great lazy day flyers. Planeman is only making my decision harder by making all of these other great looking planes available. Just the other day he uploaded other must build of mine the Lanzo Swayback.

So, here is a little mini poll for everyone, of the origional 4 mentioned;
  • Playboy Sr.
  • Keil Kraft Falcon
  • Shershaw Cumulus
  • Cobra
Which one would be the best lazy afternoon, low wind floater/flyer? Am I sick for wanting so many of these old-timer beauties?

Oh the humanity, he posted 18 more while I was typing this.

Here's a zip file containing a mess of jpg's. If you've got the time and the patience, these could be useful in developing a plan. HTH....

Thanks, I knew he had a plan, but that is first link I've seen. I will probably go that way.
