Just programmed my Rev Lock for Stator Gator Governor

[WillJames]

Hi Everybody,

I just programmed my CSM Rev Lock Governor and I am happy to report it was the easiest to program Governor I have ever setup! Once I set my idle point, with the heli running, it took less than 5 minutes to program one mode where the Gov is INH and one set to 1700. This is on my Bergen Observer Camera ship. The Rev Lock will will let you setup 2 different speeds, I chose to use 1 two position switch, with one setting INH and one with the gov active. I will post more once I test fly this weekend. :)

Bravo CSM!!

Hello William,

I need help. I have receive my statorgator sensor and revlock but I have problems to configure with the radio. I have never setup a radio for a governor or revlock before.

Here is what I have done.

-Connect the revlock to channel 7 to my 149dp (throttle servo and sensor as well)
-change INH to ACT at the governor menu at my FF9
-follow the procedure to configure the speed at the revlock in mode A and B
The mode is change by the C switch on the radio (default).

What I have missed? should I change my throttle curves?
Do you have any quick setup solution to suggest me?
Or a link where I can find a "Beginner in setting up a governor" :dontknow

Thank's

Patrick

Hi William,

It is ok now I have tested it this week-end.
I just have to adjust correctly the settings but it works.
I have programmed the first led (lowest setting 8000 to 11000 rpm).

Sorry, I was in B-Ham. Glad to hear you got it sorted out. :)

Hello William,

I have made some other test this afternoon and operate the revlock at 12500rpm for the motor. When I activate the revlock I have the tail rotor comes to vibrate like if I had put to many gain on the gyro (but it is hardest). This happen even if I chose a lower rpm or higher rpm setting. Any suggestion?
I have also change the calibration to 30% (default is 50%).

Move the responsivity to the lowest position(counterclockwise). Then tune your engine and thens start to increase it slowly until the tail starts to wag and back off a little.

Felipe...thanks for that info...mine is doing the same thing...motor is tuned to perfection (Thanks Bill Meador!) and my Bergen Gasser is smooth as silk until I turn on that dang RevLock! Then the motors sounds like crap...the tail twitches...I am ready to pull out the RevLock and just use a throttle curve only!

I will try adjusting the way you say before I give up on the RevLock...my first one was defective! So I am running out of patience with it!

Cheers,

I to am having some trouble with my Rev Lock. Waiting to hear back from CM for a couple of weeks at least.....

[patet]

Thank's for the info, I did not try with the lowest sensitivity. I will try it.
I know that the revlock in general works perfectly. Maybe the problem could come from the gatorstator sensor? The revlock could not be perfect with that sensor!
Is anyone running with revlock and gatorstator sensor without any problem?

[Flying Tivo]

In helis there is hardly anything that works perfect out of the box, evrything is about setup, my setup is perfect now, at least i think so. :?

Felipe

[patet]

Mine is not.
I measure my rotor speed and it was 2200rpm :!: I turn the sensor to nearly minimum on the revlock and still have some trouble with the tail. I do not have the appropriate rpm as well (to high) when revlock is activate. I calculate from the 7.15:1 and seems not to be ok :(
At the end of the day I have seen again the action the servo as to the carbs. I did not try again with the revlock after change. I thing this could help. I will see that next time.

Pat:

Try to go over the RevLock setup procedure you may have the rpm set wrong. Take time to understand the leds and ofcourse your math with the gear ratio you have.

Good Luck
Felipe

Hi Felipe,

I have understand the way the revlock is running. I have set the 1st switch with the first led range (8k) with the offset to 2nd 3rd and 4th led to get 11500 rpm at motor and with the gear ratio 7.15 I should get rotor speed 1600rpm.
Maybe I am wrong with the gear ratio? But I have change nothing to my kit :!:

patet,

Sounds like you could be having the same problem that I had with my first RevLock. I had mine on a 3 position switch so the middle position would disable the RevLock...now, if I would pick the heli up into a hover with the Revlock disabled and then switch on the RevLock it would work perfect..but if I enabled the Revlock when the motor was at idle and then increased the throttle the RevLock would engage but the head speed would scream like the revlock was forcing the throttle to full power all the time???

I sent that RevLock back and got a new one which now allows me to have it enable while in idle and it smoothly brings the head speed up to the predetermined RPM like it is supposed too. Now...I stil have the same over speed problem if I bail out of an auto with the RevLock enabled??? I think there might be a bug in the software of the Stator Gator version...or maybe I have gotten a hold of 2 defective units???

I will probably be contacting Len Sabato again and trying a 3rd Stator Gator RevLock....Maybe the 3rd one will work like a charm! :D

BTE: I am VERY happy in how it holds the head speed once it is engaged...I just would like it to quit over speeding my head if I bail out of an auto...to get around this right now I just disable the Revlock before shooting auto's incase I do need to bail out of one!

Cheers,

Hi Greg,

Goog to know your experience. I have also notice that if I fly then put idl1 or 2 to have the motor at a confortable speed and then engage the revlock it is working better. But only for a while :shock: After the tail start again to react like if I had put to many gain on my gyro.
I will try next time with the lowest sensitivity of the revlock. I will keep you inform.
I will also send a e-mail to CSM to ask them if they have some answer.

If you have a 9C radio you can use the governor function.
This is the way i program it:
enable the Governor function and leave the cut channal the same ch7
Then go to the switch assignment for governor function and use the same
one you use for the idle ups.
Now on the settings for each position you will have to use either side of 50%, one side is position A and the other side is position B.
It doesnt really matter wich side you use.
eg: pos1 norm cond 65%
pos2 idle 1 cond 67%
pos 3 idle 2 cond 69%

This enables you to have 3 headspeeds and trottle hold.

Of course you need to have the aux channal enable and conected in the CSM to reciever.

Hope this helps

Greg,
I experienced this problem but realized it was just the ATV in the flight mode for hold set differently than the other flight modes. What radio are you using? The Revlock is sensitive to the ATV's set when the calibration is done. If you alter the ATV's after the calibration is done it will change the point it considers for disengagement. I would like to see the ability to recalibrate the Revlock without losing the other program settings. It is a PITA when you change the throttle ATV's. The whole programming routine must be redone just to reset the throttle calibration. Mine works very well with no issues once I got all the ATV's matched. I did find that on a gasser the ATV's need to be at least 115, the servo run in non-digital mode, and the responsivity turned way down.

Good luck,
Scott

[Greg Alderman]

Scott, thanks for the info...my ATV's are all set at 100% for th throttle...guess i will have to change the ball on the arm to get the ATV's above 115%...

I 'll give it a try...

[patet]

The ATV is a point I forgot to mention. I have change mine to the max 140% but still not had time to test it with the revlock :( .

[patet]

I have tested this Sunday the revlock again and now it is working nice.
Just bad that at the end the tail pushrod break and I lost the control.

The small part of this video is when the revlock is active.

The Spectra was looking smooth... till the end there :(

Hi there,

I'm encountering a problem when setting up my CSM Revlock & stator gator for my Spectra G. The sensor check is keeping blink after I turn the engine as per the manual said prior proceed to rpm set.

Is there any trick there?

Very appreciate if anyone provide their set up procedure.

Have a good day.

Hello Joseph,

Are you sure you bought the correct stator gator sensor for your engine?

Patrick,

Mine one is GGS-23 & RL10S.
