In 47 years of building and flying I've seen a lot of kit company's come and go.
Out of all of them I've always had at least one Sig kit on my shelf in reserve and
one that's ready to fly. My kit of choice is a SIG Kougar. I built 13 of them and owned
over 20. With a .60 and retracts,loads of fun.

My opion, losing SIG would be a major blow to the r/c kit builder community.
Having Top Flite, Goldberg and others bought out by the mojor kit butchers was bad enough.
