Between the SIG Somethin' Extra (SSE) and a GP Extra 300S kit - 1st kit THE SIG!!!! I've built 3 SSEs and am currently building a GP Extra 300S. In fact, I started the Extra, had an issue requiring parts, cleaned the board, built and maidened the SSE and am now back on the Extra build. The Extra requires that you have some build experience as it is die cut (DC) and the joined wings are tapered front to rear (chord) and top to bottom using flimsy stand offs. Ya need to have a clue to get it right.

The SSE flight characteristics? Giggles-n-grins. Fly it slow. Fly it fast. Fly it on low rates and stay ahead of the plane. Fly it on hi rates and try to catch up.
