Spare V-blade paddle for R90?

[-=maxed=-]

Has anyone got a Spare V-blade paddle for R90?

The other day mine decided to keep unscrewing itself in flight.. so when i landed it was at least 20-30 degrees out :arggg:

If anyone has a set going cheap of a spare one from a crash i would be happy to take it off your hands :thumbup:

Any ideas? Thanks

Is the grub screw in the paddle no longer keeping the paddle locked to the flybar? Have you tried a new grub screw and just screwed the paddle in or out one more turn before locking it with the grub screw?
