Brick on a string - Old School

A relic from the days when radio control was expensive, crude and difficult to install, so the option for the model aircraft builder who didn't want to risk free flight (chuck-it-and-chance-it), was control line.
This was a typical profile stunter, 40 inch wingspan, profile fuselage from balsa with spruce engine bearers, built up wing and sheet control surfaces.
Not exactly crash-proof but pretty rugged.
This one is quite modern - only about 15 years old, but the design is from the sixties.
Flown on 35 foot steel wires, they could irritate the hell out of a whole suburb on a quiet Sunday afternoon as they went round and round.
These days the assembled ready to fly model with battery pack and computer managed radio control for £35 makes these a thing of the past.
I do have some glow fuel and a battery so maybe one Sunday.......
