I have a Midwest Stearman that I built from a kit. Whilst it's been a few years since I built it (and I still have it!) I don't recall that there was anything particularly complex about the build.

I have a Magnum 120 FS in mine which flys it OK.

If you have a little building experience under your belt you shouldn't have too many problems. The kit comes with a good plan and a comprehensive set of instructions.

Regards

Terry
