    I also can't find any warm and fuzzies for a 55. I think it's because the 54 and the Sukhoi style and lines just flow. The 55 to me just don't look right. But then you're talking to a guy that is totally head over hills with the 260's.

    Talking about 260, working on getting one in the air. Bought it a number years back built it and was so disappointed with that it laid around for a long time. Got over it and now putting it back together and will see how it flies.
  3. Wish I would have never sold my 108" Yak 55M. Best friggin flying airplane I owned. EME 120 was more than adaquete for power. Don't get caught up on looks, flyability is what I'm after. Look at the Corvus Racer. Noone likes the "Concept" scheme, but I do, and that airplane tracks like it is on rails.

    I like 260's as well. I even like 230's, but have never been a fan of Lasers. Even though I don't like Lasers, I would like to fly an AJ Laser. It's funny how you like some things and not others.

    The tear down has begun. I started with the forward belly sheeting and stringers. I figured that would be a good place to start. It's interesting once you get a few things out of the way, how quickly and easily the assessment of the damage can be done. I feel this rebuild is completely "do-able" now, but am equally convinced, it is going to take a "LOT" of work. I will try to get more done tomorrow. For now though, I am off to the cot in my hanqar to dream of large giant scale planes flying all around me.

    I wanted to get more done yesterday, but I was kind of spent by the time I got my friends Edge finished up. I ordered some new tools to help separate the pieces without causing more damage. My old tools are...well, old. I want to do this right and it's going to require better hand tools. I'll probably get the left forward fuse side separated from the aft fuse side and the rest of the structure today. Along with the strengthener former that runs the length of the fuse side. I'm going to do the left side first before attacking the right side of the fuse. I'm thinking I'm going to need a pattern to mirror when reassembling.

    Fighting a nasty migraine this morning and the onset of a late summer cold, I muddled through a little work on the Yak this morning. I wanted to put back together some of the broken carnage so I had some what of a template to go from when the new replacement wood arrives. The worst part of a rebuild after a crash (to me) is trying to figure out where all those silly jigsaw puzzle pieces go. And in what order they should be assembled. So the forward bottom of the belly was lightly glued together to give me some reference.

    Once that was completed, I began removing the outer "left" fuse side section. I had been told that by using my heat gun on the factory glue joints, it would aid in the removing of damaged wood. Well, why not give it a try? So I did. Much to my amazement, it worked pretty slick. Guess I will have to concede my son just might know what he is talking about. LOL. I got the forward fuse side and the adjacent F64 backer support removed and set it aside.

    Once those pieces were removed, I cleaned up for the time being the pieces that I may choose to keep in place. I don't feel there is a need to replace wood that is not broken. So, I will probably leave this side as it is until the new wood arrives.

    Next I will start loosening the can tunnel "roof"/"tank floor" so that I can loosen the motor box sides that extend from the motor box firewall back to where it joins the aft section of the wing socket rib. In the third picture up, you can see where it joins together with a doubler. F37A is the aft section that will not be removed as there is no damage beyond this point. The forward section is the major support for not only the motor box sides, but the main locating point of the landing gear block. On a smaller and lighter plane, I have "sectioned" in pieces at this point rather than replace the entire side. But with an in excess of 50 pound plane, I just am not willing to take a chance of a possible failure.

    More later......
