Default Champion Model Airplane Co. Sportster 20

I just won an offer in the market place to buy a Sportster 20 by Champion Model Airplane Company. It is a sport flyer with a 50" wing and was designed by Dick Sarpolus. Most of Dick's designs were published as construction articles first. Does anybody know what magazine and issue this airplane may have been published in? I would like to get the original article if I can. My guess is the airplane was probably on the market in the mid to early 70's, but I may be wrong.

OK, my source for old magazines did not have the issue I needed. Does anybody have the October 1979 issue of Model Airplane news that would be willing to xerox the Sportster 20 construction article by Dick Sarpolus for me?

Dave, I have been looking for information on the 84 inch Powerhouse published in Model Airplane News 1939. It was manufactured by the Champion Model Airplane Company of Woodbridge, NJ
I have just completed the framework and are thinking of making it electric.
I would like to correspond with Sal Taibi if you can give me an address.
Thank you,
Joe Redan

Hi guys,

I've attached a few photos of my latest model a " Sportster 20" sport/pattern plane from a 1980's kit I got at a swap meet for $20. The kit was based on a Flying Models magazine design article by Dick Sarpolus in October 1979. I modified the design slightly by incorporating a radial cowling and fuselage "cheek" fairings. Otherwise, it is built pretty-much according to the kit design. The kit was made by Champion Model Aeroplane Company in the 1980's, I believe.

It flew for the first time on Thursday. It now has 5 flights on it and it flies very nicely smooth and stable, like a pattern plane should! It has a 50" wing span, 400 square inch wing area, weighs 54 oz. (3 1/2 lbs.), is covered in Ultracote film, and powered by an O.S. .20 four stroke engine with APC 9 x 6 prop. The wing loading is about 20 oz. per square foot.The canopy and cowling are spray painted with Lustercote rattle-cans. The cowling was cut from a coin cup I got at the Las Vegas Hilton Hotel and Casino some years ago. I think I will need to do more work on the cowling, eventually, as the paint is starting to chip off at the edges and screw mounting holes. You know, you never actually FINISH a model airplane you just stop working on it (eventually).

The model flies fine with the .20 4-stroke and cruises easily at about 1/2 power. The .20 just sips the fuel. If I mount floats on it, I think I'll replace the engine with a .26 4-stroke due to increased weight and drag of floats, and the fact that I often fly my float-planes in the mountains at elevations of 3,000 to 6,000 feet. Right now, I'm eager move back to my Dynaflite PT-19 project!

This is beautiful looking, great flying little sport plane from "the good old days". You might find a kit like this at a swap meet, here on RCU, or on eBay. No ARF's of this baby!

Ed
