Started with repairing one of the wing panels. It has been a challenge, especially trying to free up the flaperon hinges. I ended having to open it to disassemble the flaperon. This was the only way i could  get the hinges cleaned up and moving freely. I have a bit of work left on the rib repairs, There was no instructions that came with the repair kit. So I am "Winging It"

You Boys in AK sure find alot of Avids, Winging it is usually fine 90% of the build is common sense, If you run into issues just ask of there is a manual on this site, I like that in your posts you add pictures, Keep it up,

Wow, you do have a project on your hands.  Not insurmountable though.  Was the lift strut bracket not glued and riveted on originally?  They're supposed to be.... We love pictures, feel free to ask questions as well.  JImChuk

The strut bracket was glued on, but rust was visible under the epoxy. , So i removed it, cleaned it and re epoxied it back on. Wasn't to difficult to do. Not like the flaperon.....That was a bitch!

Anyone with a 'garage' like that has the ability to get that Avid back in the air, lol. Interesting pic of the disassembled flaperon, never seen the insides before. Kinda looks like you reskinned with fiberglass instead of aluminum? Are you chopping that motor mount off and updating FWF... Ie., what engine you planning for? Lots of suggestions onsite to help increase your M.T.O.W., not much gross on the Avid A model.

No, it was the original skin. Took a lot of extra rivets though to get the shape two cans of spray foam and epoxy. I added more rivets to the underside and had to use a little bondo to fill in some of the dents from the original owner.....it actually came out weighing the same, don't know how though......I am looking into a Hirth. Not sure what model yet, really want the 100 HP model. Hirth has been around for along time and has a great reputation. and being a air cooled two stroke, its much lighter than a Rotax 912.....So yes, the engine mount gets cut off. Ill probably play around with the Cuyuna a little though. Its actually in very good shape....

We have several members in the Valley.  Very interested in how that Hirth works out for you.  We have a few of us in the Kenai / Soldotna area as well that like to build, repair and get out and fly around.

I waited 6 hours for an Avid Historian to answer you.  My best knowledge is that the A model came with a Cayuna engine.  Evidently, there was either a problem getting more of them, or Rotax came up with a more powerful engine.  Probably, most engines were replaced with the Rotax 503 -50 hp, or the 532-65 hp which came with the B model and was soon replaced with the 582-65 hp which has been the most common engine for early Avids and Kitfoxes since then.  Kitfox gave a trade-in credit for 532 engines when the owners wanted to upgrade to the 582 when the Kitfox 1 was flying.   You might find better answers in "History of the Avid" that I think C5Engineer posted.   EDMO

I was wondering about that too - Most systems say to sand the capstrips before gluing fabric.   EDMO

its been painted with ratle can primer from home depot, self etching, had plenty of it, got a good soaking into the wood. figured that should seal the wood just fine.....not sure what system im going to use yet, probably what is on the local store shelf here in wasilla. wing panel came out to just about 40 lbs uncovered.

@ akflyer, would like to view a avid plane, would like to meet with a owner to have a look at their plane, would help to answer questions about the plane.
