Women Pilots > Throttle Jockey Pro/ jr 9303 setup problems....Help!

Hello,

My name is Mellisa and I want to know of anyone besides me is having trouble setting up the Throttle Jockey Pro with the JR 9303 governor Program.

Here is what I am running. The TJ Pro gov with the opitcal sensor and a 8700G Super servo on the throttle. The Sensor is set at 2.5mm for the fan. I am also using the the JR R649 9 Channel PPM/PCM receiver and of cousre, the 9303 Tranmitter.

My problem is that I lose my collective once the Gov engages when the engine is running. As soon as the engine is shut down, my collective control returns. I don't think the throttle is being governed, because when I idle up the engines spins up, but my pitch stays at 0 degrees. If I throttle up more to about 3 quarter throttle the engines starts to over rev, but the heli doesn't even get light. So it's almost like the Collective is being governed instead of the throttle. I checked all my leads and program mixes and they are setup as the instructions say, I even talked to a pro and RC helis plus, but I have had no luck. I reset the radio to default and started from scratch several times now. I am starting to get really frustrated, but I dont want to pull the gov...I just need to figure out why it's doing this. Mechanically, the heli is setup perfect. I am running 10 degrees +/-and all the components have been checked the only thing that is keeping the heli grounded is the freakn gov. lol Help please!!!!

With the engine not running, do you have the same problem with collective?

I just checked the instruction manual for the TJ-Pro. The only way it will control the collective servo is if you plugged the collective servo into it. I know you said you double checked your wiring, I have to say triple check it. Even if it means cutting all your wire ties and physically following the wires right from the servo and into the governor. It is very easy to mixup wiring.

Make sure you have the throttle servo plugged into the spot marked "srv" and you have throttle channel out from the receiver plugged into "thr" on the TJ-Pro.

Basically what is happening is you are governing your collective servo instead of your throttle. It is plugged in wrong.

Hope this helps

Oh yeah, I did a little more research (very nice radio by the way) You want Ch 1 from your receiver to go into the throttle jockey. I still say that it is your collective servo that's plugged into the TJ.

One question for you: why the 9303 instead of the 8301?

Hi Rotory,

You are right....I think the collective is being governed as well, but that doesn't really make sense to me because I am using 120 CCPM so, it has to be a program mix because all three servos work together to process collective inputs from the radio. Geez. I keep reseting the Model program, but I havent gotten any new results. So, I have pulled all the leads and extentsions and even unbundled all the wires, maybe I hooked something up wrong. But, then, If it was hooked up wrong, then the TJ wouldn't calibrate. We'll see what happens after I redo the all the leads

Thanks for you input, please let me know if you have any new ideas !!

Hi Marked23,

I decided on the 9303 just for the novelty of it. I got it when 9303's first were interduced and wanted to try it out. I actually have an 8103, but it is installed in my Ulimate Bipe. I love it. I don't know if the CCPM program is activated on it, and I might give it a try on my Voyager50 IMZ since there are more setup sheets available for the 8103. I do like the 9303. It has a comfortable feel and the programs are pretty easy to use( except for the gov program ) Any other tips ?

JR9303/955 mCCPM
1 - throttle (from THR port in TJ)
2 - aileron
3 - elevator
4 - gyro
5 - TJ remote gain (from AUX port in TJ)
6 - collective
7 - gyro (remote gain)
On the 9303 I use channel 7 (labelled aux2) to control the remote gyro gain thru the "gyro sens" menu option. I also use channel 5 (labelled gear) to control the remote TJ governor gain thru the "governor" menu option. Assuming you have no inappropriate p-mixes active this will work for eCCPM as well. TJ calibration is a little tricky the first time you go thru it - lmk if you want info on that. To debug your issue I would unplug the TJ or set the governor remote gain to 0%. I don't have my TJ on a switch, if you do, check out what that switch is really doing.

Hi there ladymagic,

The TJ pro will still calibrate if you have the wrong servo plugged in to it, if you are a mechanical ccpm setup your collective servo and throttle servo behave in the same manner. I'd almost bet my own heli on it being a wire plugged in wrong somewhere.

Thank you COG!

I it nice to here from someone who is actually running a setup that is close to mine. You say that you dont have your TJ on a switch. How do you switch betweet RPM values? Do you have them mixed in with your Flight mode switch? Thank you though your post is extremely helpful! Anymore info you have concerning the TJ pro I would greatly appreciate. I am new to the use of Govs so I am all ears! Thanks again.

The TJ is simple but the directions suck and I had some trial and error before I got mine right. My setup is a 8103/TJ Pro.

There's four wires coming out of my TJ unit.

Sensor comes from the magnets,
AUX goes to GEAR on the receiver,
THR goes to the throttle channel on the receiver, and
SERVO goes to the throttle servo.

There's a couple other holes labeled ACC that I don't use and have no idea what they do.

In the radio there's nothing special on the throttle curve. My GEAR atv's are 70% on the high side and 0% on the low. This gives me 1700 or so headspeed when I turn the gear switch on and it turns the governor off when I turn the gear switch off.

The hardest part was actuating the gear switch on the radio, as it came disabled from the factory. I got to play in the manual and setup menu for an hour or so unlocking it.

There are tricks to making it automatically turn the governor on in stunt mode but I don't know how. But I have a working system and that's as much as I care to do with it. I like simple.

Hi Aaron29!

Thank you for your reply! You have given me some insight on what to do next. I also have an 8103 aircraft version, do you think that will work? I was looking through it's menus, and I didn't see any options for governor program. Do you have the heli version of the radio? Does it have a governor program?

Yes, the 9303 gives you free gov mixing for each flight mode. You can specify a different gain (speed) for normal, ST-1, ST-2, and HOLD. This is all in the "governor" menu option. 0% is turned off, any positive number increases the speed in a linear manner. Start at about 50% and go up from there.

Hey Ladymagic,

I was running a 8103 for many years and you can use TJ with no problem. There is no GOV function but you can use a PMix and mix
Aux 2 (TJ) to Aux 3 (Flight modes). You will want Aux 3 to be master and Aux 2 to be slave. When you click into idleup 1 or 2 TJ should kick in.

In the mix for point 1 or 5 (depending on your servo movement) I think I had that 0 (no TJ in normal flight) and then click the flight mode swith and the line should move to point 2 where you want to set this to the value of the rpm you want (I think I had -67 on my raptor 50 - TJ in idleup 1) and then if you click the flight mode switch again it will move to the next number and you can set your idle up speed there too (idle up 2) if you like to fly different rpms.

I just set up my 9303 and you have to turn on the GOV function in the dev select main menu. I put the Aux part of TJ into channel 5. I had to move my 401 gyro wire to aux 2.

I think that is it, if you go to the GOV function there are 3 settings there (unless you have activated the additional flight modes) and you can set your rpm there.

good luck

I have the 8103 heli version, but it also does airplanes and gliders. I think there's a heli mode for your 8103?

Your 8103 should be about the same as a heli version (in heli mode)except for the switch layout and ratcheting throttle action.

I don't have a governor function, but I don't need it. I just wired it like I described below and then set GEAR ATV's to turn the governor on and off. Tauscnc's setup was a little more exotic than mine. Mine is on or off controlled by the gear switch without automation. I leave the gov on always since there's little to gain from having it off unless you're setting up base curves or tuning an engine.

If all efforts fail try my setup on your 9303. You'd be bypassing the governor function but I'm sure it'd work.

By the way are there any local fliers up there with experience who can help setup the gov?

Hi Aaron,
No, there are very few heli pilots here in Minot. The hobby shop here is only just now starting to sell helis and heli spares. I only know of two heli pilots,but the are still in the learning stages and they don't even know why a gov is used.
