I built the SIg Ryan STA from plans & instructions only. Other than balsa and other woods, I needed a cowl (Fiberglass Specialties) and landing gear (bent my own wire).
I cut all the wood parts myself with a bandsaw, the then final shaping.
You have then made a "short kit" , and then assembled you have an ARC model.
Lot's of work.
If you want to go through all that , let me know.
Thanks
