Somewhere in the old 'PB' forum I had a build thread for the first kit built (besides the prototypes). In it I noted this issue. Since mine was a 'first run' short kit I tried to use spruce hardwood for the lower joiner, no way to bend it enough. So I ended up making a laminated ply V-brace joiner.
You will enjoy the KatP. It is the best knife edging 40 size bird I've ever flown and does high alpha knife edge almost as easy as regular knife.

OK, First Boo-Boo!
The lower spar pictures lead me to believe that it was cut in the middle and joined. The "cut" I saw on the pictures is a mark from a pen or felt-tip marker and not a cut. BTW, I also discovered that you can enlarge the pictures on the CD-ROM manual to your liking before printing them out. This might have helped, but I also think that the instructions could be clearer here - that you have to BEND the lower spar into place.
I remember wondering why they would have you cut the lower spar? But I thought that bending it into place was not possible because of the stiffness of the hardwood. So I cut my lower spar
. I did the same for the servo rails - but these are not structural.
I'll put a little glass tape on the bottom joint as reinforcement. Blenders are negative G's anyway, right?

What was hard about bending the basswood servo spars down? I know Matt and Clay have said this was somewhat difficult but I was able to do it with a little CA and kicker.
