Katana Repair (Ralph Doyle)

Two years ago, I was doing a normal fly –by with my KATANA when suddenly the tail virtually exploded! It tore the vertical stab completely off and also partially destroyed the elevator:

 Fortunately, there was enough elevator control surface left that allowed me to have a fairly safe landing so the rest of the plane remained in one big piece rather then re-kitting itself.  By a stroke of luck, last year while retrieving a downed plane in the corn the missing pieces of  the rudder and horizontal stab of the KATANA were discovered. I kept the pieces and over the winter I decided to see if I could rebuild the plane’s tail feathers.

I had very little to go on rebuilding the rudder. All I had was a small piece of the vertical stab.  

I decided on using solid wood rather than using sticks like I did with the elevator repair. It was a lot easier cutting out holes then trying to guess how to rebuild a rudder from scratch.  

The right side of the elevator was easy to rebuild because I was able to use the remaining left side as a template to construct the missing right side piece.(#3) and (#4) . Photo (#5) shows the completed project.

The stick formed left elevator half.

I am pleased to report that the KATANA has rejoined my fleet of flying airplanes as seen in the cover photo!
