I bought a kit and an engine sight unseen from a guy in Lincoln.  The guy said the kit was a Playboy Sr and he said it was complete.  When I got it home I found that the wire L.G., plywood firewall and all the hardware is missing as well as the dual motor mounts.   The engine is a pre war Forster 29 and it was frozen.  A little heat and WD-40 loosened it up and it runs well. I think my kit was produced about 1941 – 42 time frame.  The copyright on the plans is dated 1940.

Forster 29

Fun to Make; you bet! Remember how much fun it was to cut out all those 1/8” sheet ribs from print wood with a razor blade?  My first gas model was the Playboy Junior and I remember using a coping saw to cut the wing tips and the stab parts.  The lay-out of the print wood was definitely in the interest of saving wood and those print wood gussets shown sure wouldn’t add much in the way of strength to the wing, the grain of the wood runs the wrong way.  The print wood in my particular kit isn’t very good but the pre shaped LE and TE isn’t to bad.   Think how far we’ve come, no print wood to cut, no die-crushed parts, today we have lazar cut parts that fit and plans that are well presented.  How about the adhesives we use today?   Today when we glue something together it stays together and the firewall doesn’t come unglued either. By the way,here is a picture of the Forster 29 that was a part of the Playboy deal. The price on the Playboy box is $3.95. I think the Forster 29 sold for $14.85 didn’t it? I paid what the seller asks and I am a little concerned about the price, $35 for both; did I take it in the shorts again?

Lanz'o "PUSS MOTH" some unknown facts about this model.
by Tom McCoy

This story really begins at a spring get together at Bucky Walters (SAM 39 president) home in 1989. Our spring contest was a blowout, windy and rain, so we all ended up in Bucky's basement talking models. Somehow the conversation turned to Chet Lanzo's "Puss Moth". Bucky claimed the Moth had an undercambered wing and I said it didn't.
Well, we chewed back and forth for a while. Then, who came down the stairs but the tiebreaker him-self -Chet. This argument was happily ended when Chet declared we were both kinda right. Chet pointed out that Bucky was thinking of the small "Puss Moth", which was published in Model Airplane News March 1939. It had a 27" wing span and did show an under cambered airfoil on the plans. The model featured an 8" freewheeling prop. This was a full size plan which took four pages.
  It was a little tougher to clear up my side of the argument. I had built the large "Puss Moth" with which most of us are familiar. This is the model Chet has been most successful with and which had won the AMA National twice. It was a real flyer!
After building one myself, I was sure it had a flat bottom wing. I had lost my Moth at the Lawrenceville SAM Champs the year before (1988). Chet was with me and helped pick the good air. This model was built from the plans published by Air Trails in the forties. There was a re-do of the plans by Hal Cover in the December 1985 Model Builder which was just a copy of Chet's original plan.
This Moth was a big model. It had a 51" wing and was about 300 sq. in. Both plans showed a flat bottomed wing.
"The flat bottom wing was a mistake", said Chet. "I sent all my plans, which were on shelf paper, to the Air Trails Editor and he had them drawn up nice and pretty for the magazine. The airfoil should have been an RAF 32. The article appeared and it had never been corrected. I can prove it. I still have the model!"
We all looked at each other, ex-claiming, "You still have the model, a 45 year old rubber job?" - "Yep", says Chet. "I'll bring it to the next contest and show you guys."
SAM 39 had its July club contest at Shelby, Ohio airport. What a great place to fly models. Just like the old days, with grass airstrips and a group of spectators who came out to "see the models fly". And they brought their kids. Small town America. Just Super! It was a warm July day in a little mid-America town with a bunch of old kids doing what we loved!     Chet showed up with the "Puss Moth", a tattered 45 year old rubber job. Sure enough, it had an RAF 32 airfoil!
A side note to this story: the international letters on the undercambered wing are on backwards - should read left to right, as viewed from behind. However, my new Moth will have them on Chet's way as far as I am concerned. A big "Puss Moth" should have the RAF 32 airfoil and the letters as they are in the photo below.

The Shelby, Ohio meet was bitter sweet memory for me. Chet died on August 14th, 1989, just three weeks after the contest. Shelby was his last model meet.
