RE: Head speed & pitching up
Yup, those are the ones.
Had the yellows on my R50 in the back hole. Could not keep the nose down in FFF.
Now have same paddles (yellow KSJ) moved to my old Baron 30 S, and it handles great! :-)
Glad someone mentioned paddle alighnment. They need to be dead in alignment with each other, and also exactly aligned to the flybar arms (the part that rotates the flybar).
If pitched down, you get nose pitchy problems.
I followed Raptor Technique to the letter when I put white paddle on my 50 and it is way better than it was.
Now going to try the shrek greenies on my second 50
