I am building a Great Planes Ultra Sport 40 + and I've run into a spot I need help on. I am installing Great Planes Mechanical Retracts and got to step 25 on the plans and have a couple questions. Where the plan says "Add small pieced of scrap hardwood sticks glued between the landing gear mounts and the lite ply ribs" , where exactly is that. I can't see it in the picture in the instructions and it is not on the plans that I can see. The other question I have is did anyone else have to cut the WL-A rib to get the retracts to fit? They won't slide down all the way unless you do. And finally do people shim the retracts to the correct height after sheeting or did you posistion the mounts at the correct height before glueing them in? After I trim the WL-A rib it seems the mounts will be too low for the retract to be flush with the sheeting. Thanks for the help.

This makes me remember mine, R.I.P. I had to trim the WL-A rib also, The scrap wood is refuring to adding triangle stock where the rib and the wood block meet on a 90 degree point, This is just to give some extra strength and more wood to epoxy too. My landing gear sat a little in too so I shimed mine up but really is not needed in my opinion. The only thing about the retracts is if your landing on a grass field the legs on he gear bend pretty easy and don't line up right on the next flight after a landing so check them after every flight to make sure the go up right without getting stuck or you may need to belly flop it in the grass. It is a great flying plane too and it likes to glide in so for your first few flights go way out for the approach like it's a trainer because it glides as well if not better than many trainers I've flown.

Here is how mine came out, It was my second kit. have not finished the covering in the pics, Added some blue stripes to the wing but never got pics of it

Thanks, that is what I was thinking.

I'm just past that point on mine. The wing sheeting has been cut and glued for about two weeks now. I just can't seem to motivate myself to glue the sheeting.I had the problem your talking about with retract clearences and there are lasercuts that go one tier deeper which I had to cut out after the ribs were glued in (minor inconvience).Now the retracts fit fine.
