RE: Stinson Reliant
Also, Ikon N'west makes both a Stinson SR-8 and a Mister Mulligan. Both are about 100" wing span. Ikon kits are hand made and they are definitely builders kits. Definitely a winter project. I've built the Mr Mulligan along with their Beaver and Norseman and they are all good flyers.
Hobby Barn also has a Stinson. It's a Maurataka kit. They also are builders kits.
Finally, you can sometimes find the old Sterling Stinson kit on E-bay.
Hope this helps
