What is your set up? I'm using 720 blues on a 3-blade AS350 600size, a 5-blade MD500 700 size, and a 3-blade Lama 550 size all electric.
I pretty much use the stock scale settings and just adjust the gains through the travel adjust on my radio a JR 9503 with SAT receivers. But mechanically I am set up with -2/+12 pitch with mid-stick +5. I govern my head speed through the ESC.
The AS350 and the MD500 are phased mechanically with "J" arm links but the Lama is phase electronically through the 720.
