Default KV and gearing calculations...

Ok, so I'm trying to figure out this whole KV crap and how it relates to head speed...
And I'm not sure I have a clue what I'm talking about, so I'll bounce it off you guys lol.

I'm informed that KV + Volts = RPM...

Gear is: Teeth on Main Gear / Teeth on Pinion Gear = Gear Ratio...

So, is this calculation correct..?

Blade 360 CFX
Main Gear 136 Teeth
Pinion Gear 12 Teeth
136 / 12 = 11.33 (recurring)

KV 1800 x 25.2 Volt (6 cell) = 45,360 RPM

45,360 RPM x 11.33 (gear ratio) = 4003.5

Is this right?
