Default More Arithmatic ("Math" makes it sound hard)

BTW, the calculated HS is assuming you're at full throttle when you tach the heli.

So in your case:

3559 x what% = 3009?

3009/3559 = .85 x 100% = 85% Pretty durn close!!

BTW, you don't have to calculate the gear ratio separately if you use the formula above
