If I am understanding your question correctly, my answer is that I only bevel the control surface of the Rudder and Elevator. That will give you a max swing, end to end, of ~90* (45* bevel) Most all planes that I have built need far less than this for travel and if you need more, IMHO, you really screwed up the build. ;-) If that does not give you the answer your looking for, please try again. Thank you Chuck for the kind words and your welcome. Just sorry it took a bit longer than I intended to get them up here. On a side note, had my bug out this evening in dead air. Flights were not all that long, but they were smooth and more than a few good catches were had. Best of all, I came home with an intact Bug!

Each photo has been marked up with a short note as to what is being done. #8 has been marked up to show the difference between a "T" spring and a "Z" spring. I use guitar string but salvaged spring wire from a 3.5" floppy disk is a good size wire to use as well. Just straighten it out and bend as needed. > > > > > > The pictures did not post in order but should be viewed form #1 to #8 to see the steps. Hope this helps you guys out a bit.
