I just finished getting caught up on your build. I am most interested since I recently became the recipient of a partially built SIG Ryan STA. I've rounded up most of the missing parts such as cowl and misc balsa and plywood. I don't have the instruction book. After reading your posts I will have to back up a few steps before I can go forward. I like all of your additions of reinforcing in stratigic locations. I may not need the instruction book it if I follow your build. I can only hope I can do as good job as I have only repaired planes and never built one from a kit before. The rudder, horizontal stab., wing, ailerons and front half of the fuse is built. I'll need to remove some sheeting on the wing in order to reinforce it around the landing gear and joint of the wing halves as you have done. I like the idea of flaps so will be making that modification as well. I will have to make all of the parts for the back half of the fuse I looks like this was partially framed but not sheeted at one time but got severly damaged. I have both side panels but no bulkheads. I'll be using a Magnum 91 4 stroke with onboard glow. I have to move the firewall back a little to properly position it in the cowl. If you have any suggestions or build tips that aren't in your build posts please, please, please let me know. Wish me luck.
