HI Eric,
Link to RC Scale Builder:
https://www.rcscalebuilder.com/default.asp Unfortunately, it is pay site, you can browse, but can't post unless you subscribe. I don't post there very often myself as most of my builds are sport planes, and they are very strict about only allowing scale models. I bought a lifetime membership there a few years back when they were offering a very deep discount. If it wasn't for that, I probably would not subscribe.
Count yourself lucky if you managed to get a Stinson Interior kit on order. After Hobbico got bought out by Horizon Hobbies, all of the Top Flite kits and kit accessories were discontinued (including the Stinson and the Stinson interior). Top Flite ARFs are still in production, but the kits are no more
. I was able to get mine a few years back.
I always struggle with having space for the kit boxes during construction myself. These builds do tend to take a lot of space!
