I welded in my 'bar slugs - then decided to drill & pin them too.. The reduced section was done by hand with the trusty grinder and finished with a file as I don't have a lathe. That's what I think of as old school.
I am starting a build & set-up service for R.C. airplane kits - fixed wing only - no helicopters! I have been modelling most of my life having started in the ''launch and pray'' days of single channel radio and free flight. I fly foam these days but it still helps a lot to understand model airplanes well - and saves money & grief in the long term.. EPO foam & balsa kits built and radios installed plus full set-up service.
