I will second your Yes and No answer by saying this:
- Yes, I have experienced throttle creep with my original Rotax springs, mainly in the first hours of flight when I did not know how to adjust the throttle friction correctly
- No I do not experience throttle creep after 100 hours of flight and leaving the friction system alone after founding the sweet spot.
As always, FWIW
