head speed, new thread old topic:)

[fusionsx00]

So I messed up by not doing the right calculations before flight

But I have now, using darkhorse head speed cal
On my motor scorpion 2208 24 3590kv on 3s lipo
Full voltage
15t=5089
14t=4750
13t=4410
nominal voltage
15t=4483
14t=4184
13t=3885

The stock gaui motor is 3400kv @3s lipo
full voltage
15t=4820
14t=4498
13=4177
Nominal voltage
15t=4243
14t=3963
13t=3680

Im going to run my sk720 gov @ 4000rpm
in order to get there I need the 14t, I got it from radicalrc.com
right now im on the 15t pinion, no gov

My motor has a custom 2.3mm shaft
im using a 30amp pentium esc, with a cc bec@6v
im getting 329 max watts drawn
and 28 max amps, crazy power

Im just wondering what actual headspeed the scorpion 3900kv
On a 14t


My kit came with the 3400 gaui motor and a 15t pinion
The manual says 800mah 3s lipo
I'm running 850mah 3s, but im getting 1100 45c packs

This is crazy head speed like my x5 and 200
The x5 is running a 16t pinion like around 2600rpm on 500mm blades
My 425 was @ 2800 with 425mm blades.
