AR7210BX E-GOV wont startup
Hey guys, been at this for hours. Cant get the E-gov to start the motor. If I turn the Gov off, it will start up right away so I know its not the ESC/motor/wiring. YGE 160HV, scorpion Ultimate in the heli. Using the Dx9.
I got the red light after turning the motor (A), confirmed the low throttle point (B), the high throttle point (C), but having trouble with the D gov menu on the AR7210BX. It says for normal mode to be at a flat 0, but of course the motor won't startup when I do that. I set normal mode to 25% flat but still nothing. To get the motor to turn again I have to go in to the BeastX, turn the gov mode off, go out of the menu, go back in and turn it back on. It works in the setup mode ONLY if I don't have it at a flat 0 for normal mode. Either way, once I'm out of the setup mode I cannot get the motor to spin up. What am I doing wrong here? Im LOST and completely aggravated. The directions are completely confusing because the e-gov and Nitro gov stuff is all mixed together. Can some one give me EXACT directions how to get this going please? Ive setup numerous nitro govs on the BX without any issues, this is my first time trying to use this e-gov. Any help would be great. Thanks

I haven't done it yet. But going to. Have you try rebinding? For the safe fail start. Or whatever it's called?
Edit. Smart safe system |

Haven't bothered rebinding yet, need to figure out why I can't get it to startup with the Gov menu -N- on, but if I turn it off...it starts right up. Something in the gov menu OR in my TX is wrong. Just not sure what exactly.

Try it and see. Just thinking about that smart safe feature. Or may have to re do your throttle end points calibration for the Fbl gov mode.
I'll prob be doing mine later in the next couple of days on my 700l top I did research and have no found anyone else posting on if they have done it yet. Like either no one cares to and uses the ESC gov. Crap nvm about the throttle end points. I had to re read your post. |

Look on page 31 in the manual.
"Using the RPM gov"? |

Hi Aaron,
I'm trying to understand exactly what you're experiencing on your end based on what you typed, so forgive me if I've got this wrong... Step D (Adjusting throttle curves in the transmitter) of the governor setup menu is only used to help you correlate where the AR7210BX plans to set the rotor (motor) rpm versus a signal coming from the transmitter. For example, based on the chart on page 25 of the Spektrum AR7210BX manual, if the AR7210BX interprets a 0% signal from the transmitter throttle channel, it will set the motor to OFF. If the AR7210BX interprets a 25% signal from the transmitter throttle channel, it will set the rotor rpm to 1000, etc. It's important to note that a 25% setting on the transmitter's throttle curve might not necessary be interpreted as a 25% signal by the AR7210BX. This is why Step D of the governor's setup is there... so you experiment and (if desired) map out various transmitter settings against how they'll be interpreted by the AR7210BX. I'm not familiar with the YGE 160HV ESC, but does it have settings to disable any sort of "soft start" and/or "slow rpm change" features? Those need to be off when using an external governor. Best regards, John PS: Assuming you have everything programmed correctly in the AR7210BX, then the heli motor should definitely start moving if your transmitter sends out a throttle signal up near say 50% (zero on the DX9's monitor screen). |

thanks for trying to help
I tried everything guys, dumped the idea and setup YGE gov store like I normally use. Disappointed really. So many hours into it. It just won't start the motor no matter the settings or setup in the YGE or BX. Threw in the towel. Starts up and holds fine with the ESC gov. Oh well....

GravityBlows have you revisited this problem of not being able to use the ar7210bx gov and maybe found a solution or did you just give up? im about to start a build and will be using the 7210 on it and after reading the included manual came away with more questions than answers. so maybe you can answer a couple from your experience so far.
first, you said you went back to using the esc built in governor. did you just deactivate the gov mode on the 7210bx in step "N" and step up the esc gov mode? also is a fbl controller governor any better or different than an esc gov and does one work better than the other. im using a castle on another heli and as far as im concerned the speed controller works fine for me. but after reading the ar7210bx manual i was interested in trying out that gov mode to conpare. hey thanks

I never gave it another try, I put in a lot of hours trying to make it work. Id prefer the FBL gov, but the YGE does a pretty good job at governing. Ive asked around quite a few places, no one could give me a correct answer as to why its not working. Not going to fight with it anymore, gave up. Its something to do with the the way the YGE is talking to the BX, probably endpoints. But I haven't a clue, Ive tried everything.

ok thanks, for how i fly i would think my esc (cc) will be fine, but i understand how not getting something to work right feels.
so how do you like your ar7210bx? ive got 2 3gx installed on 2 500s so this is my first non-aligned fbl do you use the "safe" bailout system?

I have a few flights on it now, flys great. A lot more stable than the 7200, cyclic and tail very locked in. I like it, no real need for the bail out stuff, i didn't bother downloading it. Nice to have that option for people just starting out though.

Have you tried Horizon Hobby's tech support? They are usually pretty awesome.

Aaron im sitting here reading the manual for the 7210 and have a question about you problem. it seems you need to have a sensor inline from fbl to motor or an esc with a built in rpm sensor to the fbl. i didnt see where you stated that you were using one. so did you miss that part of the fbl gov setup or did i not read that you had that hooked up?
thanks

Nope, got the sensor all hooked up and its working just fine. I tested it.

Damn I saw this and thought HEY this will have the answer as I am having the exact same issue! But Noooooo, no answer. Matter of fact I put up two posts asking this same question in different ways. I have yet to get even a post to either one and this I guess is why. There is no answer at this point.
I do think the ESC is the issue as I did not program it, I just used it from the box. It is a HobbyWing 100A. I ordered the programmer for the HW and will see if I can get in there and turn off the GOV and solve this issue. Ill post what i find. |

I tried everything, called Horizon, spoke with Spectrum people. Nothing. I used the YGE gov, the hell with it. Spent too many weeks trying to get it to work. No luck. YGE gov works just fine.

Now step into Microbeast/ar7210 setup menu, skip to menu point N, choose electric governor option. At menu point A you may apply some throttle, also here the motor should start to turn immediately, just like in normal operation. Led should get red as long as the motor is turning (also turning the motor bell by hand should give a red light when the sensor is sending rpm signals). Proceed to governor menu point B, set low throttle point by applying stick input just before motor starts to run. Here you must be very precise. The low throttle point must be just one "click" away from the motor starting point. If you do not teach this correctly, the motor will not start later onwards, as the system does not apply throttle unlimited but only in a very narrow range. If it does not see any throttle after a few steps it will not increase the throttle any further for safety purpose! This especially is important if your ESC does not cut the throttle at the same point as throttle starts (ie. this is the case on Align RCE-BL ESCs). If you increase throttle, the motor starts to turn, then close throttle until motor stops and then you save this last (stop) position, this will not work. You have to remember the position when the motor did start and only move the throttle just before this position, then push the button to save (use the servo throw or throttle curve setting in the transmitter for this purpose and remember at which value the motor did start, then just move the throttle 1 point before). At C move stick to full throttle, nothing special here. Hopefully full throttle is really the point of full throttle! If you did program throttle positions in the ESC, we can expect this. Otherwise you may check at point A or in operation mode before, if and at which point the motor speed will not increase any further, reduce high throttle endpoint in the transmitter accordingly. At D you will now see the governor switch positions when you move your throttle stick. At the very low position LED is off, then it gets blue which is bail out position, then red all the way up until purple at the max. As we want governing here we don't need any stick dependant change on the throttle channel. Now set your curves for each flight mode, i.e. a flat 0-0-0-0-0 in normal mode, so here the motor is off, no matter where the thrust stick is moved to. Then for idle up make one curve for the first head speed preset, i.e. 50-50-50-50-50, to get 2000rpm, and then idle up 2 with let's say 55-55-55-55-55 which transfers to 2400rpm. Then make an additional curve for throttle hold or set the hold value, if there is only one value to adjust in your TX. When triggering the hold switch the Status LED should get blue, as seen before. This should be somewhere in the range from 10-15% on your TX, but may vary, depending on the low throttle position you've set at menu point B. Now if you do the test: normal mode = LED off, idle1, idle2 = LED red, hold = LED blue. Switch back to normal mode (motor off) and proceed. That's it basically, setup the other menu points (gear ratio, rpm divider) if not done already. Then when out of the menus it should work right away. When in normal mode nothing happens when moving the thrust stick. Now switch into idle up, the motor should start to twitch and then turn slowly and then motor speed should increase slowly (hopefully you've removed rotor blades before for doing the test!). If the motor does not start within let's say 2 seconds, it is very likely have not set the low throttle point at menu point B correctly. Again, make sure the low throttle point is the point at which the motor is just one hair away before starting to turn! If it's to far away from the actual starting point, the governor will not be able to start the motor, as it does not increase throttle blindly for safety purpose.

Amazing info. It looks like a nightmare to do seeing it in text. I was wondering how the gov in bx would work as I am setting mine up tomorrow. I was just gonna go with castles governor now I may try the bx first.
Ty for the detailed explanation. Last edited by Curt S; 01-23-2017 at 08:17 AM.. |

Hi Frenchdress,
Thank you for your instructions on setting up an e-gov. This has made a big difference to the way my heli (Align 470LM) spools up. Previously I had to set the throttle about 3/4 stick to get any spool. A few things I noticed though... After setting (increasing) the correct low throttle point using your method, the throttle hold % point now has been increased approx 15% to get the blue status light to come on. Does this sound right? When the heli spools up on the ground, there seems to be a couple of surges of HS. Is this surging effect normal for the slow rampup? Rampup speed is set to 200rps. Note the align ESC is set to aircraft mode (not heli) Thanks again.
