I have a Vigor CS, OS 70, JR 10X and G550T gyro. Problem is with the GV-1 governor. After spool up and the governor takes control everything seems OK. I vary headspeed with Aux 4 and governor off/on with Aux 2 switch. The only way I can get the governor to disengage is turn Aux 2 switch off. Throttle hold switch appears to work OK when engine is not running, but does not work at all after GV-1 takes over. Lowering throttle/collective stick also does not disengage the GV-1. I need help.

I used the following page to set up my GV1 with a 10X. I even used it to set up an 8 channel receiver on my 3rd bird. I had to make some minor changes but it helped the setup. The important thing is to make sure that throttle hold shuts off the governor. I watched a guy crash when he lost his tail on a fury and could not shut off the governor.

Someone recommended mixing the throttle hold switch with Aux 2 since I am already using Aux 2 switch to turn the gov off and on. He says the throttle hold switch will then also work.

Anybody ever tried this?

HoseA, if you set the GV-1 up with the Stsw enabled your stock throttle hold setup will work the GV-1 too. This is how it works: The governor uses your throttle CURVES, not the position of the throttle/collective stick itself! So, first you do the setup by telling the governor your stop, idle and full throttle points. Now that the governor knows where on the CURVE is the idle point is (with the Stsw turned on) the GV-1 will switch on automatically when all these three things happen; the M/R RPM is 70% of the speed you set for that flight mode, the on/off switch is ON and the throttle position is at least 20% ABOVE THE IDLE POSITION YOU SET on the throttle curve!! Now you ask, how will the throttle hold work? Easy! The TH setting is BELOW the 20% movenemt on the throttle curve required to engage the GV-1! So even if you have the on/off switch in the on position, due to the TH going to a point on the CURVE that you set as the idle point the governor stays off! The same thing happens (in reverse of course) when you go to idle up to fly inverted (should you be so inclined)...because the idle up throttle point won't go BELOW the "idle + 20% point" on your CURVE, the GV-1 stays engaged even if you move the collective stick to the bottom (negitive pitch). Just remember, the GV-1 uses the curves you have set in your radio...it doesn't care where the left stick is physically! I hope this helps. Chris

Thanks, Chris. Your explanation helps a bunch. No one has ever explained how these things work to me before. I THINK I understand much better now.
