I have had cl models come in at me - -been over 50 years tho- I never thot of it as a snap roll - just going too slow -stalled out etc..
actually out run some of these and saved em!
I flew Brave - Super Duper Zilch- Barnstormer and stuff like that -
then I finished up with 1/2A stunt stuf I flew on 50 ft of .008 braided wire - in 1969-
all that line drag assured no fast rolls just a gentle roll as the thing tried to get me --
