Throttle Friction Nut. An Essential Extra for hand
adjustment.
The preset friction often gets either too loose or too stiff in flight.
A scap plastic knob was modified to suit - extra weight 20 grams - with the original Rans nut pressed into a counterbored hole at one end of tight fitting Ali insert turned in a lathe to suit the knob core.
To avoid withdrawing the existing securing through bolt [to put on a 'non turn' tab washer] & risk losing all the bits threaded on it, its head end it’s trial secured in situ with a spot of superglue.
