I have built and flown the 4 Star.

I've also just completed a build of the SSE. Will try again next weekend to maiden that one.

SIG kits are the best I've built. Laser cut parts is just one reason why this is so.

I like the way my 4 Star flies. It is aerobatic enough, but the low wing, and slight dihedral in the wing do limit what I can do with it. It was my third build after the PT-40 and an Easy Sport. I chose the 4 Star mostly for its looks, and the fact that it was a low wing tail dragger design.

The Somethin Extra, with its mid-wing design is supposed to be much more aerobatic. No one at our club flies one, so until we get mine in the air I have no first hand knowlege of its capabilities. But I have read that it is as tame, or as wild as you like. I like the fact that it has individual servos for each aileron, (unlike the stock 4 Star). With a computer radio, you can play around with flaperons and such. I did read that the main gear have a tendency to break out on hard landings. Some reinforcement there might be a good idea.

I'll let you know more after we get the SSE in the air...
