My Kraft stuff is 60+ years old, the futaba stuff is generally 45, the newest one is 35. The aircraft the radio stuff is installed in is maybe 30 years, except for the .050 gasser trainer with an unknown assembly date (got that in an estate sale). Futaba at the time was modified Japanese military design equipment sold to the public. Nice thing about futaba: 50 years later, it still interchanges with new non computer formats and you can still buy new factory replacement parts.
Not seeing much of a reason to buy new radio stuff. If someone gave me a brand new system, I would use it, but I have no desire to buy new.
