Greeting Pro Bro's!

Things are starting to take shape on the KatanaP. I epoxied the wing and stab in place last night. This part of the assembly was an area of concern since starting the project. It turned out to be quite easy. During covering I left a 1/2" center strip on the wing and stab un-covered by film. This would ensure a strong joint.

The fuse was place in a flat vise and level such that it was exactly perpendicular with the building board. I then fit the wing in and moved it around until it was centered and perpendicular to the fuse. I then used a level to ensure that the wing was parallel to the building board. The top of the wing is flat so it gives a good surface to level.

When everything looked good, I made some alignment marks with a pen, applied epoxy, and slipped the wing in. I used the alignment marks to get the wing in position. Excess epoxy was wiped away with pre-prepared cloth wipes dampened with denatured alcohol. Wing alignment was triple checked and allowed to cure. Same process with the stab, using an triangle to ensure that trailing edge was square to fuse. Hey, flat fuselages have their advantages when it comes time to square things up!

I took a lot of time to make sure that this airplane is as true as I can get it. I learned from my experience with my UcanDo that alignment and surface deflection are critical to 3D airplanes.

Here is how it looks now. The distinctive Katana wing fillets are to be added next.
