The following question came from William Snow
I saw you did not build in the washout on the Chrysalis, but got there by the covering pull?
It would help to have the shims in place for the wash-out at the time the diagonal braces are installed, but it's a minor point. In general, having the wing panel flat on the board during assembly of the structure is a lot easier for beginners, it helps with things like getting the rear spar caps properly seated in al the ribs, and getting the tail ends of the ribs lined up with the trailing edge stock. The big advantage of a wing with no D-tube balsa sheeting (besides not having to worry about beginners getting bubbles and ripples in the sheeting when they glue it on) is that if they do build it with a warp, they can easily straighten it back out at any point later on. They can also experiment with different amounts of washout to learn how it affects performance and handling. The down side is that the plane does need to have some periodic maintenance to make sure the washout hasn't shifted, but that's not all bad, either. We designed the Chrysalis to be, among other things, a good training tool for beginners, and it's good for beginners to learn to regularly give their airplanes a detailed going-over, and make sure everything is the way it's supposed to be.
