that is what you need to put in the "gear ratio" tab
Also make sure you have 0-40-40-40-40 for normal, 60-60-60 for st1 and 100-100-100 for st2 and make sure you did the max and min throttle calibration. verify by changing normal-st1-st2 and check the percentage of throttle in the gui.

i want to confirm with the throttle max and min throttle calibration. does the throttle curves need to be linear ? from 0 min and 100 max? |

Here's the checklist I go by that I've had the most luck with when setting up the SK540 governor.

You don't have to use linear curves: you just need to make sure your TX is outputting 100% when pressing "MAX" and that its outputting 0% when pressing "MIN"
If you have set normal and ST as described you could open your throttle curve graph, put in normal + stick all the way down verify 0 in TX and press MIN and after put ST2, verify 100 in Tx and press MAX. Same goes for ESC calibration. that is how i do it. If you are not sure about why and how go threw the procedure Rodney wrote, to be on the safe side.

For Scorpion, HobbyWing or any other ESC, 1. Set ESC to external governor mode if needed (e.g. Scorpion ESC) 2. Plug in SK to computer 3. Turn SK gov OFF 4. Throttle curve 0-50-100 and end points at 100 5. With throttle at low and click Set Idle Throttle 6. With throttle at max and cick Set Max Throttle 7. Unplug SK from computer 8. Calibrate the ESC's high and low according to the esc manual 9. Plug SK into computer 10. With throttle at low and click Set Idle Throttle again 11. With throttle at max and click Set Max Throttle again 12. Now select Electric Gov mode in the SK 13. Set High Ramp and Low Ramp at 80 14. Reset throttle curve as per SK instructions, gear ratio and rpm. For Castle ESC, please follow the the following (courtesy of Nick @ RCHeliNation) 1. Set CC ESC to External Gov Mode 2. Plug in SK to computer 3. Turn SK gov OFF 4. Throttle curve 0-50-100 and end points at MAX 5. With throttle at low and click Set Idle Throttle 6. With throttle at max and cick Set Max Throttle 7. Unplug SK from computer 8. Throttle endpoints at 70 or so and calibrate the ESC's high and low according to the CC procedure 9. Plug SK into computer 10. With throttle at low and click Set Idle Throttle again 11. With throttle at max and click Set Max Throttle again 12. Now select Electric Gov mode in the SK 13. Set High Ramp and Low Ramp at 80 14. Reset throttle curve as per SK instructions, gear ratio and rpm.

Re: sk540 gov
I have to say, Georgi, that's the most concise post yet that I've read on the SK governor setup. It's also the first time I've seen one that gathered up the information for multiple ESC types. Thank you.

My maiden flight went great. I have a little bit of drift. I also have the same with a vbar heli. I think my DX7 is struggling to keep center. Probably need to get a new TX.
For faster servo response, is the only way to achieve that through raising the head gain? Are there deadband settings in the Sk540 similar to vbar? Have not messed with the advanced settings yet. |

Yes! For changing your dead bands. Look in the control tab section on the bottom to set your dead bands. It is right in the middle column. I fought through an older DX8 to finally get mine to quit reading a nose down command for days. The new Spektrum program to supposedly fix that sucked big time. And took roughly 20 tries before it got close.
But you can widen the dead bands in each section of the Skookum for Elev/Ail/Rudder so the Sk doesn't see the errant signal. But it does deaden the off center commands on the heli a bit. Reminds me of flying with a BX when they are wider.

Thanks I will check it out. Is there a max. safe number to use in the deadbands?
I have a 450 with a 3gx and it doesn't have the drift. I guess it has a wide deadband by default? |

You can check if that is your problem with the GUI - connect and whatch the live values from your Tx. Preferably after a flight when you have it. Tx output might change with temp, for example if you stay in the shed but fly in the sun.
You also asked for faster cyclic - higher rates, higher bell gains and higher hiller decay will give you that. Experiment with one at a time. Default 3D values are very low except the HD

Thanks. I'm going out today to try 2 different setups and see if that helps.
I looked at my TX cyclic (ail, elev, and rudder) values on the bench. They start at all zero. However after moving them around a bit, the rudder consistnently returns to zero and the other 2 show 0.2 or great variation when letting go of the stick after moving them in full circles. I guess my TX is not centering well. Now to figure out a good deadband value until I get another TX. Was thinking of getting a Spektrum DX18. Hopefully it doesn't experience the same condition. |

on the first tab verify you have 0.5 for elevator and aileron dead bands.
Good luck testing!

When initializing the sk540, should the heli be at zero pitch/mid-stick?
Right now I'm initializing at full negative pitch and wasn't sure if this would make a difference or not. |

No, not at all. When initializing the Sk the swash or pitch location shouldn't be an issue. This sometimes varies with different esc's that want the throttle above zero though.
