Pretty much straight forward, I doubt you will find much to challenging. If any area that needs attention its the wing tube sections. I did find a very tight fit on one side and much less on the other. This is in regards to how the aluminum tubes slide in and out of the winga phenolic tubes. What I did was to sand the inside of the tubes with fine sand paper wrapped around a dowel that was as close to the ID of the phenolic tubes as I could find. Do this before you install them into the wing panels. You may not have this issue as it only takes a fraction of a thousandth of an inch to make a difference. Check and swap around the phenolic tubes with the aluminum tubes and you may find pairs that work perfect together than just mark them accordingly. The other area would be mounting the P-80se. You will find that an extra spacer will be needed to raise the engine up a little so you can move it forward or the bell will hit on the wing/fuse center section. Some guys will drill a hole large enough to put the start motor up into the fuse section but I did not. It is just shy of hitting the fuse and my balance was not an issue. When you install the phenolic tubes into the booms you use the fuse section to help align them up while the glue dries. It will mention in the instructions that this is important in how tight the booms to fuse and wing to booms fit will be. I used a couple cargo ratchet straps to kind of pull it up tight together while it dried, worked great. Just be careful not to damage the finish but as long as you use common sense its a safe way to do it.
