The new Sig Somethin' Extra has it all - good looks, incredible performance, Sig quality balsa and ply construction and every part in the kit is laser-cut!
This kit can literally be built as fast as the modeler can apply CA glue and accelerator. Fantastic flight performance using either 2-stroke or 4-stroke engines. The aerobatic capabilities of this model are virtually unlimited due to its thick airfoil section and very light wing loading. A perfect club contest airplane.

Special notes about electric from Dave: This model makes an excellent electric conversion. My first large electric was one of these on 20 1750FAUP Cells. Yikes, I'd love to do another one with modern packs! Here is how I'd do it. Yes, this is same chart as the 4 Star 40, similar weight and wing area. An under recognized yet excellent electric conversion model. Good weight to wing area. A little troublesome to get large NiMH packs into due to the wing tube. However, with Lipo's it's super easy to fit the pack. Below are my suggestions for a range of practical power systems.
