What is the clearance between your sensor and the fan magnet ??

If the gap is too large, the sensor could be picking up the signal intermittently....

Also, what is your headspeed without the governor engaged ??

With the governor engaged ??

What are your ATV setting ??

Yep, Paul the MA designer and owner was great and beyond but after selling to the guys at heliproz has just become marginal, what a shame.

Your problem could also be engine tuning, because if the engine can not stay within 20% (or there abouts) of set rpm it will kick off.

To answer your questions.

What is the clearance between your sensor and the fan magnet ?? .5mm

If the gap is too large, the sensor could be picking up the signal intermittently.... Not the prob

Also, what is your headspeed without the governor engaged ?? I have no idea, it wont turn off to see!!!!! It should be 1500 -1700 like usual

With the governor engaged ?? Same answer

What are your ATV setting ?? 30% on the Aux channel and 100%-100% on throttle

Could you be more specific on the symptoms? Is the throttle pulsing? If so is it fast or slow?
I have had the throttle pulse very fast and tracked it down to the throttle servo (9254) was too fast for the motor response time. I had to take the gov. out of high speed servo mode, and all went away.
If it is a slow pulse that sounds more like engine tuning.

JP....
A couple of things......

First, you have to make sure your motor is running right and that the pitch and throttle curves are set up properly BEFORE you attempt to use ANY governor....

That being said, I like to set up the TJ on a switched channel so that one side of the switch turns the TJ OFF and the other side of the switch turns the TJ ON. I like to use the "gear" channel, although there are many variations depending on your likes/dislikes.....All 3 of the TJ Pro's I'm running are set up that way..... 0 on one side of the switch and 50-60 % on the other (see below)

Thirdly, you need to know what your headspeed is..... 1500-1700 "as usual" is too ambiguous.... and here is why...... your headspeed without the governor engaged HAS TO BE AT LEAST AS HIGH OR HIGHER than your "target" headspeed. In other words, if you want a "governed" headspeed of 1700 RPM, your headspeed needs to be AT LEAST 1700 (OR HIGHER) or you stand the chance that the TJ won't engage properly....1500 to 1700 "estimate" is to large a range to work with.

Fourthly (if there is such a word) your ATV of 30% on your aux channel is way out of whack..... it should be in the order of 50-60 or maybe even higher depending on how the calibration was done...

I would recommend that you set up your TJ on the gear switch or other "switched" channel so that you can turn it on or off at will and then work on your settings as suggested above. The "gap" you describe in your answer sound fine...

Good luck and let us know how you make out....

5 mm are too far. The manual say " The sensor must be less than 2mm away from the surface of the magnet"

I don't have a clue what you're talking about here, but I have 2 RevMax and a tach and Kurt has ALWAYS gone above and beyond to make sure that me and the crew here are happy. All you have to do is contact him.

I had this happen with an old "regular" throttle jockey several years ago. Turns out that I had it set on too low of an rpm. After I tweaked it up a bit, everthing was fine. Sounds like your engaging at too low of an rpm. I also use an enexpensive tack that mounts to my tail boom to get proper rpm. I only use it when fine tuning. I can tell by ear to within a couple hundred rpm what the blades are turning. The tach does help though. I have my tj pro hooked up to a 3 pos switch....off,1750rpm, 1900rpm, it all has to do with the percentage you set up on the switch. I think below 50% and it will not work. My 1750rpm is at 73% on the switch throw.Gas is Great

Kurt at Model Avionics is great to deal with and always willing to take the time to get any situations squared away.
If you are still having problems with your TJ give me a shout and we can hook up and get your TJ working properly.
BTW which radio system are you using?
