 MultiGov Pro FAQs
Do you have any videos to help with setup?
How do I get more recovery power for fast pitch pumping 3D maneuvers?
I am running a Spektrum 7100 dual-voltage receiver or similar, are there any special connection considerations?
Is the Spektrum motor backplate RPM sensor compatible with MultiGov?
How do I mount the RPM sensor on my T-Rex 600 Nitro?
Can I use the Align RPM sensor with MultiGov?
How can I  reduce the amount of overspeeding during unloading of the rotor?
I am experiencing some periodic motor surging/oscillations in hover. Alternatively, the motor does not seem to run smoothly during hard flight.  What should I do?
What can I do if I hear a motor "hiccup" after I unload the rotor?
What can I do if the rotor speed spools back too slowly after I do a throttle hold and then abort the throttle hold?
   
Do you have any videos to help with setup?
Finless Bob at Helifreak.com has an excellent set of overview/setup videos.  Many thanks for his work!

How do I get more recovery power for fast pitch pumping 3D maneuvers?
You can increase the "LowThrotPcnt" basic configuration option so that the lowest throttle position MultiGov will go when controlling overspeeding is higher.  This can improve RPM recovery for fast pitch changes.  Adjust to your liking.  A good value might be in the 35-40% range.  You may experience more overspeeding the higher you make this value.

From our testing and feedback, this is more beneficial for .91 sized motors and the YS50.  If you are running a OS .50 Hyper motor, going beyond the default setting is not usually needed since the OS .50 Hyper typically runs a high RPM at low throttle.
 

I am running a Spektrum 7100 dual-voltage receiver or similar, are there any special connection considerations?
When connecting the RPM select input to the receiver, please remove the red wire from the extension cable.  This avoids any problem with conflicting input voltage levels.  MultiGov only needs the power line (red) coming from the receiver throttle output for operation.
 
Is the Spektrum motor backplate RPM sensor compatible with MultiGov?
Yes, it will work without any problems.
 
How do I mount the RPM sensor on my T-Rex 600 Nitro?
Please click here for step-by-step instructions.
 
Can I use the Align RPM sensor with MultiGov?
Yes with modifications.  You must switch the red and black wires on the sensor and replace the connector with a standard servo connector.
 
How can I  reduce the amount of overspeeding during unloading of the rotor?
You can decrease the "LowThrotPcnt" basic configuration option so that the lowest throttle position MultiGov will go is lower.  The default setting is 30% above idle.  You can try to lower it to the 20-25% range.  The downside to having this setting too low is that you may not have consistent smoke/motor noise.  Depending on your helicopter, you may also run the risk of disengaging the clutch during flight if set too low which is not good.

Another option is to increase the “BaseGain” value to see if that helps.  Try increasing “BaseGain” by 10-15 point increments.
 
I am experiencing some periodic motor surging/oscillations in hover. Alternatively, the motor does not seem to run smoothly during hard flight.  What should I do?
Possible solutions are:
1) Double check that the sensor is securely mounted and that the magnet moves directly over it.
2) This could happen if your motor needles are too rich.  Try leaning out the needle settings.
3) If that doesn't help, go the Advanced Configuration menu and try decreasing the "BaseGain" value by 10-15 point increments.
 
What can I do if I hear a motor "hiccup" after I unload the rotor?
Try and lean out the low/mid throttle needles to see if it gets rid of the problem. Optionally, your motor may have a rough spot around the low throttle range which causes the hiccup.  You can avoid the rough spot by increasing "LowThrotPcnt".
 
What can I do if the rotor speed spools back too slowly after I do a throttle hold and then abort the throttle hold?
When you do a throttle hold and the rotor speed drops very low, the slow startup is re-engaged when you abort the throttle hold.  To have the rotor speed startup faster, set the "Startup Speed" value higher in the "Advanced Configuration" options.  Increase to your liking.
