Thanks to everyone on RCU that posted building advice on the Sig Something Extra. Just finished mine and will maiden it this week. There was a lot of "Don't Know How" put into this build. First build in 28 years, first monokote experience [:'(] and first fiberglass cowl. It is patterned after YEL 914's SSE. Big thanks to Yel for taking the time to tell me how to build a fiberglass cowl. Here's some pics.
