Update. I've completed the build of both top and bottom wings. and the horizontal stab. So far so good. I still have a ton of sanding to do, but I'll do that last.
One thing I've noticed is; Balsa USA did not mention in the manual the different lengths of the 3/8 by 1/4 sticks required for different areas of the build. So, I'm off to the LHS to buy a few of the 36 inch versions since I used them for my spars. I just found out that I need the 36 inch ones for the longerons on the fuse build. The splice should be under the plywood former on each side, and the shorter ones won't work. Oh well, I need more glue anyway.
I'm still debating whether I will use my CRRC 26 in the pup or buy a Zenoah 26. I prefer the electronic ignition Zenoah, but don't see the G-26 ei version on Horizons' web site. There is another Zenoah 26 with a different prefix but I can't find any reviews on it yet. Has anyone used one?
