hi,

i've been looking around for a while and i see that
a lot of people here use pretty high nitro% in their
fuel, like 15% to even 30%? Sometimes even heli-fuel?

Why is that?
I run 5% at max in my Saito .91 and it runs super!
But now i'm gonna put it in a 3D-plane so i wondered
if i would need higher nitro...

Thanks,
Wouter
