Control line speed

I think tethered car racing pre-dates control line flying Dave

As pertitle this is Andrew Robinson setting the New Zealand record No cage neither

And this is Paul Eisner setting a World speed record for the 2.5cc IC powered FAI class back in 2001. I think the record has been upped a few times since. None of it for me I'm afraid, used to like the team race with John Bowman, but it would be a dull old world were we all the same and NO the props not broken

Yes it is monoline Dave, you can see him doing the pull test on it in the first few frames. The fiitting on the pylon does prevent him from whipping but its main purpose is to keep him and the model centred in the circle. If you watch the first I think two laps he whips like crazy to help it get on the pipe and then it's an almighty rush to get it locked in the pylon. I once saw a pilot at good old Woodford fail to get in the pylon with a 10cc speed job and it dragged him all over the runway, people scattering in all directions and he had to ditch it Interesting to note the pilots are all built like racing whippets
