Can some please check my setting.
I am trying to get head speed 1600 1800 2000 rpm. I am using a dx8.

Compass 7hv v2
Compass Motor SZ4926-510kv
Main gear 127T
Pinion 14T

I program mode 1 then mode 4

Pleas see attach pictures.

you have heli jive mode 6 selected instead of mode 4. Also don't take the headspeed calculator numbers as the gospel they are never 100% accurate.

Hey thank you, this is my first kontronic esc, I saw the word helijive in the calculator and thought that was meant for the helijive only.
My kontronic 120hv is version 11.

I think I need 13T pinion, see photo below:

Yes 13t looks perfect for the 2000 HS you are looking for @65% !!!

As Joe mentioned it looks like you are good to go 65% is the target and your required head speed is right at that point.

Ok so far I got this:
I program mode 1 and mode 4.
I set trottle % to my three way switch.
0 - 0,45,45,45 1600 rpm
1 - 55,55,55,55 1800 rpm
2- 65,65,65,65. 2000 rpm

My first spool up is at 2000 rpm @65% until governor kicks in.
Do I start off in my idle up 2 which is the highest head speed.
After that I can start off with normal and then switch to different head speed in flight.

you can start off in any of the curves. it basically sets a sliding scale that sets all headspeeds associated with throttle input so if you started at 45% and then went to 65% or started at 65% you would have the same headspeed either way. just make sure during start up in normal you arent moving inbetween 0-45% as its trying to set headspeed.
