I have the flap controls between my seats on my 2+2 project but have not come up with a good setup for the flap control lever yet. In looking at some PA-22 interior pictures, I see that the flap lever for the PA-22 would work perfectly in my Wag 2+2. I have the Short Wing CD but it seems to not have the drawings for the flap lever. The ratchet and other parts are there but not the flap lever. The drawing I am looking for is #12494 Lever Assembly - Flap Control PA20 serial #'s 20-1 > 689, 691, 692, 696 > 704, 22-1 > 4 . It is also listed as #13185 Lever Assembly - Flap Control PA22 Serial #'s 20-690, 693 > 695, 705 +, 22-5 +. These numbers are from the index on the CD but these drawings are missing. Does any one have the drawings of the flap lever? I have a picture of it from Univair but a drawing with dimensions would make it a lot easier to duplicate. Thanks for the help.

There's a flap handle for a 22/20 on eBay right now. Not sure if that helps your project.

I checked out the listing, thanks. The pictures will help if I can't find the drawings. Thanks for the heads up.

I not ever seen the drawing. I will see if I have a handle that I can compare to the Super Cub handle. I take it that drawing is available?

If anyone has a super cub type flap handle for sale, I will send the tri pacer flap handle I have here to Marty and I will buy your flap handle. Being tandem, I can't use the pacer flap handle.

The flap lock mechanism between the Super Cub and the Pacer/Tri-Pacer is the same, angle, length and cable attachment are different.

That picture is very helpful. When the flap handle is raised, does the ratchet pivot? It looks like the nut has a cotter pin in it? I would need to weld in an attachment for the ratchet unless I bolted it to the plywood floor with a metal brace under the floor similar to rudder pedals. I think the Pacer flap lever could attack like what I currently have, Picture below. What I am missing from my setup is the ratchet. I have the PA28 mounting cage that has the indents for this flap lever; no idea of flap angles. It seems to just bolt to the floor in the PA28. I had to raise the flap lever and cable above the floor to clear the push pull rod for the elevator just below floor. I plan on making a inverted "V" to cover the cable. Thoughts?
Thanks,
Marty

If I were able to redesign the Pacer flap handle mechanism, I would put it overhead. It cuts cable distance and reduces the number of pulleys. And, it would be easier to reach especially when getting rid of the flaps quickly at landing.

Although, your setup looks good with the handle between the seats. The ratchet is attached to the frame on one end and floats as it slides through the flap lever. A pawl is released when pushing the button to lower the flaps. The angle of the flap handle and the ratchet changes, which is why the ratchet is curved. Attaching the ratchet to the floor boards would seem to work although, it might not be as stable and allow slight changes in the flap adjustment.

With adjustment I was able to pick up 7 more degrees of travel in the flap. Also, it is possible to add a third notch in the ratchet.

I thought about doing overhead flaps but decided against it. I didn't like the idea if the flap handle being down , possibly blocking the door in an emergency. I think in a Super Cub it makes great sense to go with overhead. I also didn't want to go through the design process for overhead; between the seats was the easiest. Looks like I have a Pacer flap handle on the way, thanks Gary. I think if I reinforce the floor at that location I can attach the ratchet pretty easy. Depending on how it fits, I may be able to weld the tab to the existing cross tube. At least now I have a firm plan, I think ......

Thanks,

It's amazing how guys here seem to have my back even when I don't know it's needed. After posting that I was looking for drawings of the Pacer flap handle, Our own Pistoncan came to the rescue and sent me a Pacer flap handle he had from his fuselage. I sent him the one I had for some horse trading we seem to be doing back and forth; I got the flap handle today. It fits perfect! I will weld up a bracket for the ratchet that i can bolt to the two uprights that the flap handle mounts to. The bolted bracket will allow me to fine tune the location and make any adjustments I may need after I start flying. It sure is nice how things work out with lots of guys looking over my shoulder. Moving forward !!!!

Marty.. I still believe this is the best type site on the web. (Okay the Supercub site is close!) More like a large family with everyone jumping in when someone needs a hand. I think it may have something to do with the people who started the site....the two Steves and Cathy are really nice "down to earth" people and that is reflected in the "tone" of the site.:icon_biggrin:

Curly,
You are right on target about these two sites. One more flap handle question; if I want to remove the spring and rod so I can sand blast and paint the flap handle, how do I remove it? There are two small slotted screw heads on either side of the flap handle about a third the way down from the release button; do these come out? What are they threaded into? Any one have a picture of a flap handle apart?


Thanks,
Marty57

Marty, you wouldn’t happen to have measurements on the attachment point at the frame. Mine must have snapped of at one time and someone put a hose clamp in its position. Need to fabricate one and weld it in, just can’t seem to find the drawings on it.
Thanks
John
