Kit's???? ****? there is almost none available!
There are lots of kits available.
Balsa USA
House of Balsa
Sig / Herr
Great Planes (check Tower Hobbies)
Eureka
AK Models
Bruce Tharpe Engineering
IMP Scale
Several others on my short list
plus kit cutters who will make you a kit from one of the many plans makers
and some innovative places like WOWplanes
If you can't find a kit to build, you're not looking very hard.
Best wishes,
Dave Olson
