Bug HLG

Hi Colin, I wish I could build with composits as you do. Your carbon Bug is beautiful. The crashes were much easier to repair than I expected. When I left the field after the Zagi collision, I half expected to build a new wing. When I figured out what parts needed to be replaced it wasn't so bad. It took one evening of cutting (and much pondering) and one morning of gluing. I have been very impressed with the strength of the built-up ribs and the Bug wing. I did use your patterns for the tail. Thank you! All that I changed was to increase the percentage of the movable areas. I don't know if I needed to, but I remember reading that deflecting a larger area a smaller angle results in less drag. I put the horizontal stab on a pylon so the control horn would be in line with the fuse boom and I could run the pushrod within the boom. And I mounted the vertical fin as close to the centerline of the fuse boom as I could while allowing room for the pushrods to exit the tube. With the cruciform tail it does launch straight with no presets. When you get your carbon Bug repaired, I'd suggest you try it without the gyro.
