Someone started a thread on a 1/2A slab wing with flaps. I couldn't find that one, but thought I would share my new 1/2A with flaps. Have not flown it yet, maybe today.

That looks like fun!

That's very interesting, Duke. What' the base airplane?

Bill-This is very close to the drawings, called the Wing Master. I flew it yesterday, it flies pretty good ( lazy 8's, loops, inverted, and a bad wing over).

Well it sure is a sharp looking airplane. Glad it flies good!

Thanks. I did crash it a little. There's a couple weak points that should be corrected, like where the flaps go through the fuse.

Hi Duke,

I would like to see one built with the same wing area, but no flaps, to see what difference flaps make in that configuration.

I might do that, I would like to remake this one and then the flapless

My brother and kids built the Wingmaster backin the 80's. They flew quite well as I recall. I've never tried flaps on these little 1/2A planes, but yours makes me want to try one

Fix the flaps with the flap pushrod taped to the fuselage, then use a pushrod straight to the elevator, can be done between flights at the field.

Where can you get plans for one? I've searched quite a bit but cannot find any references to and airplane, just a shotgun

So this is what I know about the Wing Master. I have drawings that are about 24"x18", with blue print over blue 1" grid lines by Jm Petro. It might be Jim, but the I don't see the (i) to make it Jim. They are marked May, 1981 and in the bottom right under the title block there's the number 377. This said, just in case someone remembers seeing drawings like this in a magazine.

The Wingmaster was published in Aug 1982 in Model Aviation, Jim Petro designer. Plans are available from AMA and the article is online in the MA Archives.

There you go guys. thanks John

Bill Johnson · « **Reply #14 on:** July 09, 2013, 04:22:15 PM »

Thanks, guys! I'll get a set of plans. Sometimes it takes me some time to get projects going and this will be no different as the wife and I are going house-hunting in Huntsville next week, but I pretty much always follow through. My longest running project to date is a 1903A3 Springfield I bought in 1992. Bubba had it for years, apparently. Finally finished the restoration in 2010.

Looks good! Mine was a barrel of laughs until I started to do squares, there's just no time to react!

Might have to build another

Other than building the nose out of balsa and ply, the only other thing I would change would be where the flaps go through the fuse. It's to weak. Almost every time I take it out the fuse breaks at the opening for the flaps. I would either make the fuse out of 1/8" balsa and two pieces 1/16" ply or not have the flaps go through the fuse (which would be the lightest I think). You could put a small piece of ply on both sides of the fuse and join the flaps with a wire. I just put it back together after flying it tonight. This time I pushed two toothpicks in for strength.

Curare · « **Reply #17 on:** July 10, 2013, 07:39:08 PM »

I fitted a half moon of 1/64" ply over the cutout to strengthen it on mine. It didn't break there, but did break the wings off a half dozen times.

Man, it's comforting to hear that I'm not the only one who spends as much time fixing as I do flying.

Oh yeah, not funny! I have it all back together now, just waiting for the wind to stop.
