Nearly all gliders have strong springs on the rudder pedals which
tension the cables. A rudder cable failure will result in the rudder
going over to the other side and there is nothing you can do with your
feet to prevent this (unless you can hook your foot under the pedal on
the unbroken side and pull it forward).

What was the altitude AGL ?
Where is the JS1 rudder vented ?

Sure lucky it ended OK for the pilot !
Best Regards, Dave

I am surprised that the rudder went full over, and slip would not center
it
Rudder vent?
Does not the JS-1 have an extractor dorsal vent?
WE should test controlability with feet off!

One must wonder why, and if there was no safer way to design the rudder pedals mechanism so it wouldn't aggravate the situation in a case of cable break.
