I have built and flown (3) Cub models over the years. All have been Sig kits, so I can't comment on the other kits that are available. I built the 1/6 scale full span version and the clipped wing version, and the 1/4 scale clipped wing. All are really nice flyers, but what I liked the best about these kits are the way they look!!! I think Sig has done a GREAT job with these kits!!! I'm even considering getting another 1/6 kit!
