RE: Sig Something Extra vs. 4*
The SSE flies something like a Twist but on the gentler side and will land very slow on a dime.
Set the throws to no more than 1/2 inch on low and anyone with a little experience could fly it.
The SSE is a very nice kit to build.
Unfortunately, I lost mine in a mid-air collision as 2 other guys were flying the oval the Wrong Way!
SSE = TOF.....Tons Of Fun!
