Throttle Jockey FAQ

[modelavionics]

I'll keep adding to this post....

Futaba calibration. (9C, 9Z)
Set the ATVs of the AUX channel to 95/95 (not 100/100)

Calibration General
Toggle the AUX channel *within* the 1st 3 seconds after powerup. Dont wait for the Gyro to boot.

Calibration.
Remeber to set the throttle stick *and trim* to the lowest postition before entering calibration.

Cool thanks for the info Paul! Looking forward to flying the TJ Pro's this year. I was over thinking the setup at first but she is all setup now just need the weather to fly hehehe.

Chris

P.S how is the wi-fli going?

[cnsheets]

I was over thinking the setup at first...


Definately true.

But after you get it, you realize how simple and easy it is to use. and setup.

[Sluggo]

Yup you are right about that. I think most people coming from running GV-1's will do the same thing but when they really start to look at it they will see how easy it really is.

To get a faultless calibration on the 9Z I found that assigning the channel to a 3 position switch and throwing it exactly 4 times to enter calibration and the same to leave calibration, whilst leaving the throttle trim at idle gives the best results...

:D

also have 2 tjpro and I have to admit I was tearing my hair out trying to get it work, until I finally realized the atv on aux 7 had to be 95 95. Once that was sorted out wow I love it

keep up the good work

[conrod]

Got one that will be here tomorrow.
Best link for setup on JR 10SX.
Presently I'm using my gear channel for my gv-1 and aux 3 for gyro gain.
Any help/links will be appreciated.
Look forward to trying it out!!!

ps...it's going in a fury and ys91 motor. :cool:

NEVER MIND...FOUND WEBSITE :)

Question.....during calibration, with aux ATV's at 95/95, throttle trim down and stick down, do i need to set the first point of my throttle curve to 0% or do i leave it where it was in normal flight mode?

I've tried calibrating it several times and with the bird wound up i through the gov switch and it doesn't govern.....the only thing that i notice is that once the switch is moved there's a rythmic-momentary rapid increase in throttle. Has nothing to do with stick position or switch position. Once toggled it'll increase throttle for less than a second about every 3 seconds.

Any suggestions?

[Bonsai]

In order for the TJ to work and hold your target rpm ..the heli must first hit the target rpm for at least 1 second befor the tj will maintain that rpm. if you never hit that rpm then the tj will not engage. try setting one of the positions of the switch to a lower rpm say like an atv setting of 50. And see if it holds that rpm.

I tried exactly what you said today.....no luck.

Correct me if i'm wrong, but isn't 50 what you put in to disable the governor? I'm using a 9c, governor assigned to 3way switch C....bottom position set at 50% (disable) middle and top i tried adjusting to determine if i was just way off on my numbers.

I'm only adjusting the numbers in the governor menu....atv's on the gov. channel haven't changed from 95/95

I got the headspeed high before flipping the switch, high enough that i was getting nervous. So, another day i flew with the governor function INH.

I guess i'll have to wait till i get a chance to fly with some of the locals that are using a TJ and see what they think.

[Bonsai]

No the TJ kicks on and off by throttle position and I thinks its 15% of throttle position that turns it on and off. Or a value of 5 or less (ATV)on the Aux channel input. Here's what I would do...Check and make sure that you get the red light when the sensor passes the magnet..Then I would re calibrate....Set your Aux channel input values to 100% atv's ...put throttle trim all the way down or in the off position.Then turn you heli on and toggle your switch till it enters calibrate. raise and lower the throttle at leat 3 times and then toggle the switch again to exit calibrate. Set your ATVs in the Aux channel to 0-45-65...and then check your light s to see that the TJ is in fact coming on.0 will not come on as its off but 45-65 should be on. I have 3 TJ's and a gv1 and I will trade my gv1 in a second for a TJ...Mine has never missed a beat unless I did my setup wrong..And I have... :arggg: Really if you follow the directions to a T you cant go wrong...oh I think I see what your doing wrong. I went back and reread your post.. you said you have a 3 position switch make sure when you calibrate all 3 are set to 100.
I hope this works for ya.
Dean

[tyuditsky]

So I recalibrated and figured it all out.....red led blinks when sensor passes...green light goes out when disabled or below 25% throttle.

The kicking is it "governing the headspeed"

I set the ATV's for testing purposes to 1% above 'disabled' and then 2% above.

Can fly all day in the disabled position and it disables it this time. Throw the switch and it appears to hold the headspeed. Add pitch (to slow the headspeed down) and this is when it starts to kick. It acts like a gyro w/gain too high, fighting itself....once the headspeed starts to slow down, it'll apply heavy throttle for a moment, then it realizes it gave too much and cuts back almost to an idle and the cycle continues endlessly. I tried adding a couple more points to the atv's and that didn't help much.

The manual pot on the unit doesn't affect anything when controlling it remotely, correct?

Just shootin in the dark for ideas now.....

What kind of servo are you using on throttle there are 2 settings for T/J Pro
Ray :D

[jhodges]

I've been having a really bad experience with my TJ Pro. I bought it over the GV1 so I could run a Digital (Fut 9253) servo with it. After many attempts (by me and others with TJ's) I can not get it to work in super servo mode. When activated it "pulses" the throttle and "freaks" out.

Yes, I have it calibrated exactly as posted (I have 9C) and the servo works great on a tail with 401 gyro.

Funny thing, I put a regular/non "Super" servo in (Hitec HS525BB) and it works ???

[Bonsai]

If you are using a super servo you must turn the claibration mode off while the light is YELLOW and not Green..to do this you must keep the throttle at the full position and then toggel the switch...It sounds like you are not calibrating properly and thats why it is surging...I had this problem once in the past and found that my sensor was moving around in flight...but I really think yours is in the calibration....I love my TJ........It works so much better than my GV-1 that Im in the process of trading my gv 1 for a TJ... Here's what I would do if I were you..I would go to modelavionics web site and they have the entire set up posted there..Follow the instructions to a T....and if it dont work leave them a message and Paul will get back with you within normally 24 hours...I had to do this the first time I installed my TJ...then I figured out that I was just another bonehead and had skipped the step that says the throttle trim has to be all the way down...I have been running mine now for over a year and it has been flawless except for the one time above... I recalibrate mine all the time as Im always changing something on the heli..But honestly.......There is no better...
Dean :glasses2:

[jhodges]

Thanks Dean but I done it all .. :( I guess I'll get with Paul. I have followed the Super servo procedure as you explained.

[tyuditsky]

USER ERROR----the official cause of the problems i was having with the TJ.

Here's what i learned through this experience:

1. Set all values for whatever switch you use to 100% before calibration.

2. Being 'safe' and only putting the ATV's one or two points above disabled is going to have the TJ attempt to govern a headspeed out of its range and the tail will kick.


That's right, once i bumped the atv's back to where they were originally recommended, the thing worked. And i like it! Now its just a matter of dialing in the exact headspeeds i want.

Thanks to Bonsai, without everyones help and my temperment, my TJ would have ended up going through the window and into the trash.

[ArthurKnowles]

Thanks for posting this information. It is just what I needed to get my TJ Pro working on my Shuttle with Futaba 9 CHP. I wish the instructions had of mentioned that calibration requires a switch set to 0 on one end and 100 on the other. Luckily I only spent an hour (including my google searches) to find the answer.

[ShawnK]

and if it dont work leave them a message and Paul will get back with you within normally 24 hours


Unless your'e flying an Airtronics Stylus, in which case you'll wait for over a week and still get no response. :arggg:

[Greg Alderman]

Buddy, did you just try to get a hold of Paul? you do know he sold Model Avionics to Kurt right? Paul is working for Horizon full time now with the Specktrum radio stuff. He also has been at the Joe Nall event all week...I ran into him on Thursday there...

Later,

[ShawnK]

No, I wasn't aware of that. I just used the "Contact" link on the Model Avionics website.

How does a guy get a hold of Paul?

Things are starting to make more sense now... didn't MA use to advertise the coming of their "WiFly" system? I noticed it had disappeared, and now there's all the Spektrum stuff.

Hello,
I just put in the TJ pro and have a few questions, after reading the post's in here i was able to get it calibrated so thanks everyone for that. So here are the questions. I'm using a Futaba 9C super.
First off let me say that my Throttle curve is at 0-25-50-75-100 in normal, Throttle trim is all the way to the bottom, end points are at 95/95 I'm using the Vr-B knob to control the governor.After calibrating everything seems to work as it should, BUT.....
1- I'm not 100% sure how to get the engine to idle, I have not started up the engine yet but when i put the throttle to where it needs to be to idle the TJ pro thinks it needs to start governing. The green LED light comes on. So how do you set it up to just idle before you go into headlock mode?
Hope this makes sense.

Thanks
siavreg

I think i may have it, I'll get back
