Wascamp,
Good day building today with the kids. You mentioned 8th graders, unfortunately they are all seventh graders. Only experience in the room is one kid who's brother I taught to build and then later taught to fly his own trainer. Out of the 70 kids I have building 4 planes a year, a handful (maybe 4 or 5) actually ever get their own plane. Last year I gave an RV-4 to one of the kids because it had two hard landings and I was tired of it. Turns out the motor needed a new bearing. But that kid actually has 4 planes now. Best story is a kid who is now attending Purdue for aviation He actually did his Science fair on the pitches of different props. Back to the build. On page 18, the lower picture shows a former that is not yet installed while #4 is being installed. Correct. One of my guys tack glued some CA on the outside to give the wood glue time to bond. Spent quite a bit of time sanding when the class left. Thank you for the tip on the 1/4 square pieces. I'm going to chase a few pieces at the hobby shop tomorrow for the fuse group. Please tell me where I can find that part about the windows not being glued solid? I believe you, I just can't find it. I am a little worried I might make the same mistake later somewhere else. One kid today built part of the flaps and ailerons, then he became a photographer. Photos this evening
