I built one and had a ball with it...
Only two suggestions
1. On the prints it showes two positions for the landing gear one for grass and one for pavment..."use the grass" (If I'm right it's the position most towards the firewall) Cause if ya don't and the plane is balanced it'll nose over on landing every time...
2. If they have not changed the prints it showes no sheeting over the ribs next to the fuse...SHEET at least the first two bays...cause if ya don't the ribs will warp and pull when ya shrink the covering and it's a mess building up the ribs so they match the fuse sides...
With a Sato 91 to balance it the battery had to be in the tail just forward of the elevator...
See ya..
