Hello Ashley
Control line flying is still in existence and is nice to watch, mainly for nostalgic reasons
We have a very active club flying at weekends on a quiet area of Barton aerodrome in Manchester
There used to be an international event club in Wigan called three Sisters……Named after three local slag heaps! The Russian models were immaculate
The speed models were enclosed in wire cages and was very exciting to watch…. they only ran for about 15 seconds and they used single bladed props!
I used to be a member of the Ashton club and just for the novelty…..Had a control liner rotating around a central pylon and RC controlled.
It actually appeared in an article in the RCMA magazine
I suppose that you could Google the aircraft parachute info?
