Is this your model?  (upper left) I'm confused by the three types listed on the SAM website.
Did it fly well?

Yes it is--This is the type 1 (one) wing--That makes it rare--When the article was published in the magazine, it showed a picture of the model being hand launched--It had a type 1 wing--When everybody ordered in the plans it showed the type 2 (two) wing--Boooooo hissssss!!--I got the type 1 wing plans from John Pone and they were a disaster--Totally out of square, tapered, and different lengths on each side etc etc--I redrew the plans and went that way--There were no dihedral angles or dimensions anywhere to be found so I used Playboy Sr angles--Who is to say it's wrong--The originals don't exist--Pond also included a set of rib templates, (very bad) which I figured to be the standard 6409 shape--The type 1 wing is longer than the type 2 wing and has more area--If you intend to build one go to great pains to build the after end of the fuse and tail feathers light--It's an awful short nose--I flew mine with several different engines in it from a Hornet to an O&R 60--I believe the original had a Dennymite--My favorite combination was with a Super Cyke on ignition, gas and oil with a Rev Up 12x5 prop--With an Anderson 65 it was potent--With the very long tail moment arm it doesn't stand on it's tail but is still very fast climbing--The glide is a beautiful floating one--I kept incidence at 1 1/4 degrees and CG at about 74%--It has a big stab--Mine came in a 8.1 oz per square with the Super Cyke, Hitec 555 receiver, Hitec 81 servos and 650 ma batteries--I use 350 ma telephone batteries for ignition--I hope this helps you                                                       ......Hank 

Years ago, I built a full size Ehling Request for class A chosen based on how well my dad's .020 replica flew.

I discovered that a lot of liberties had been taken with the .020 version compared to the Air Trails drawing.  But when I got the Klarich kit with the Pond plan things were even worse. It had a 44" (left side tapered!) and a 22" stab.   The AT article indicated it would be 11"

All this seems to be quite standard--All screwed up--Interesting about your dad's 020 version--I built one back in the 70s with a pee wee on the nose with a coil of fuel tubing for an engine run timer--I had tons of fun flying that on dead calm summer evenings--Another model of that series that was a blast to fly was the 020 version of the Brooklyn Dodger----Again a pee wee on the nose--I had it trimmed out to fly right/right and caught it in my hands many many times on dead calm summer evenings--I was living up in NJ back then and there was still room to fly FF--I started flying RC in 1952 because it was  new experience--I actually built my first model that flew in 1943, and my first gas model that flew in 1948--A Buccaneer "B" Special with an O&R 23--Lots of room for FF--Now I don't know of anywhere you can fly FF here in Maryland so FF is over for me  .....Hank Baer

Flying Rag

Hi Tom, I saw an old article in an old magazine of a Cox .049 engine attached to a small block of wood and two shop rags hanging from it. Bob Stought at our meeting said he had one that he had flown a dozen times and a few days later presented it to me. See picture attached. You get the engine running and give it a twist in the direction of torque and send it straight up. The rags each with a knot in the end swing out with centrifugal force and it goes up like a helicopter. He said it works great. The rags are saturated with oil presumably from the exhaust so I have to believe it. What could be simpler. Not a good glider though.

This video is an addendum to the engine and rags: http://youtu.be/cquvA_IpEsA

Willie's Back!

I have some good news ! Willie is back, safe and sound. I spent a week distributing fliers in the Nashville area with no luck, then someone suggested CraigsList. I found out what that was and made up a very descriptive ad, offering $50 reward. That was Saturday afternoon, and Sunday afternoon I got a phone call from people at Murfreesboro (about midway between here and Nashville) saying they had him. Description two white spots on his head and he talked with a Brit accent ! I went up there to collect him, not really believing it until I got there, but it was Willie alright. He apparently flew through the thick woods when he disappeared and came out at an unfamiliar place. Not being able to find me, he went to someone else for help and they took him home to Murf where they already had a female parakeet ( I should have such luck ! ) I'm sure that without the $50 reward they would have kept him because they said they would put it toward another bird but Willie was easily worth that to me. He sat on my hat and studied me all the way back on the 40 minute drive and when we got into town here he started to recognise places. When I opened the car door to get out he shot off for the front door and when I opened it he made a beeline for his own little house. I trimmed his wings a little and it hasn't affected his flying but his rate of climb is reduced ! Now he doesn't like me getting more than six feet away from him. The impossible done immediately, miracles take a little longer ! ERIC CLUTTON

Clearly, Willie needs to learn his address: http://wap.myfoxny.com/w/main/story/60165915/
