RE: SIG Somethin' Extra Props and Servos
I've had both the ARF SSE and I've built one from a kit. Both flew comparable. I did have a couple issues with the ARF though. First, the rudder hinges broke. The hinges included with the ARF looked more like what you see from World Models or somebody, not the typical Sig CA hinges. If you haven't already installed these, it might be worth upgrading to genuine Sig or Great Planes CA hinges. Secondly, the firewall came loose after quite a bit of flying and a lot of snap rolls. My kit built version never suffered from this because I made sure it was epoxied and supported well. Now, I check all ARF's. If necessary, I add a fillet of epoxy around the front of the firewall and epoxy some tri-stock on the back side if possible. It doesn't take much time and could save a nice airplane.
