I have a Raptor 50 with a plastic head, plastic grips and Maverik carbon fiber blades.
I've been reading that over 2000 headspeed is dangerious.
But with a 8.7 gear ratio and 2000 headspeed the motor rpm is around 17400 rpm.
The only problem is the motor (ys 56sr) doesent start to come alive till 2150+ headspeed.

Whats the good rpm for a ys56?
And am I going to blow up my head at 2200 headspeed?
Im at high altitude 4200 feet above sea level.(incase that matters)
Using 30% fuel.
