Thanks for posting this! Very enjoyable!
Interesting to see the split between proportional and reeds (looks about 50/50?) and also the number of Bonner Digimites there! (Still got mine, bought 2nd hand in 1968! Very reliable!)
I'm sure I recognise some of the people present (Fritz Bosch flying the original Simprop gear? H.J Nicholls judging?) - will have a closer look later! Also enjoyed seeing the variety of models, especially the Mustfire, always a favourite of mine!
Brilliant stuff from an era before contest models all started looking like fish!
