Hello Everyone,

My setup:
Raptor 50 FBL conversion from TT
JR xp8103
JR 7ch rec.
Throttle Jockey
BeastX FBL controller

Hello Folks!

Recently took my Raptor 50v2 Flybarless. I have everything setup and working well. I actually was just outside hovering the chopper for the first time( with a training gear) testing. My main question is that: now that I have integrated the BeastX into the setup, i have lost command of the throttle jockey governor. In my old stock setup I could control the throttle jockey with the gear switch. Now, with the BeastX I'm using the gear switch to enable\disable HH mode on the beastX. I tried flipping the flight mode switch N,1,2 with no change on the throttle jockey. I know this has to be something simple such as a TX setting... Any assistance appreciated! Thank you!

Hi

It's been a while since I've set up a throttle jockey, but if you are using the gear channel for gyro control then you can use aux2 and mix it into flight mode 1,2 on switch. check your JR radio manual for program mixing, I believe it's aux2-thro then set paramiters you want and select on what switch you want it to be activated on. I hope this helps!

Hey rednoseraptor!,

Thanks for the tip. So I've had a few test flights or hovers to see if the TJ is working. I have my gear switch turning on\off heading hold on the BeastX. That seems to be working OK. I have my control wire from the throttle jockey plugged into AUX2. I an disable and enable the TJ (the green light goes on and off and I can see the sensor light lit) but it doesn't seem that the TJ takes over at any point. I copied my old TJ ATV values from my pre-FBL model setup and have them configured as before. Once I spool up I never get the feeling that the TJ is engaged even though all indications look so. Once I take off the engine lugs a bit as expected to lift the heli. I remember when I actually had the TJ working nonFBL the engine wouldn't lug because the TJ was regulating the throttle to keep the headspeed dialed in. Does this make any sense what I'm trying to explain?

Thank you again in advance!

AustinHeli,

Is this how your 7ch receiver happens to be connected:

I think not, since you stated you're using the GEAR channel to enable/disable Heading Hold for the rudder. That tells me you have the gyro gain connected to channel 5 and instead of enabling/disabling Heading Hold, you really have two gyro gains -- one heading hold, one rate mode gain.

That leaves channel 7 to be hooked up to the TJ Pro RPM setting input. What in your 8103 is slaved to the channel 7 output, and how is that tied to the flight mode switch for control? What does the slider for that channel do in the MONITOR window when you flip the flight mode switch?

-----

Digging out my 8103, I see that you have three choices for INPUT in the "Input Sel" menu for AUX 2...INHibit, Pitch Trim (a knob), and the HOLD switch.

The Pitch trim knob is a bad choice, it's a knob, is in a really bad place to get to and you end up with only one value as set by the position of the knob. And it isn't slaved to the Flight Mode Switch.

The HOLD switch is a bad choice, you'll actually want to USE HOLD for throttle hold. I guess it would work, but the HOLD function becomes pretty much useless.

If you leave Input Select for Aux 2 INHibited, you can in turn enable the Gyro Sense feature, and set it to AUTO. This will connect the channel 7 output to the Flight Mode switch, and you will have two values available. One for Normal flight mode, one for the two Stunt Modes.

---

You could get creative with programmable mixes to run a governor setting out of channel 7 (the one you seem to want to control RPM with, and the AUX 3 which is the flight mode switch (channel 8).

Playing with the 8103, using AUX3 as the master, and AUX2 as the slave, it seems you can do stuff with MIX 1, MIX 2 and MIX 3 to get three governor control values out of channel 7, allowing you to get three separate RPM settings.

-----

I tried the following:

PMix 1:

AUX3 -> AUX2 (AUX3 Master, AUX2 Slave)
POINT H -> 0 (I actually set all points to 0 or INH)
SW: F-NR (Flight Mode, Normal, rear position)

PMix 2:

AUX3 -> AUX2 (AUX3 Master, AUX2 Slave)
POINT 2 -> 75 (I set Point L, 1, 3, H to 0)
SW: F-S12 (Flight Mode switch, ST-1, mid position)

PMix 3:

AUX3 -> AUX 2 (AUX3 Master, AUX2 Slave)
Rate: 0%
-85%

SW: F-S2 (Flight Mode Switch, ST- 2, forward position)
Offset: 0

-----

Using those settings, looking at the MONITOR window and the AUX2 (Channel 7) output slider, for Normal mode, I have an output of zero.

The POINT H setting in PMIX 1 allows me to set the Normal mode output value from 0 to 100, and the governor setting for Normal mode. Looks to be linear.

The POINT 2 setting in PMIX 2 allows me to set the governor RPM for idle up 1. 0 is zero, 50 is 50 and 100 is 100. Looks to be linear.

The Rate setting for PMIX 3 sets the Idle up 2 RPM setting. 0 selects 0, -100 selects 100%, numbers in between are linear.

In the Travel Adjust settings, I set both values for AUX3 to 0, although this doesn't appear to have any effect on operation.

The HOLD switch appears to do its thing, looking at the MONITOR window, and it also appears to change the RPM setting for normal and Idle up 2 to zero (disabling the governor in HOLD mode, but I don't think that's a problem).

-----

May not be the easiest answer, or the right answer, but it appears to be an answer that at least on paper, seems as if it would work with no unwanted behavior.

Thank you Dave for your answer and effort! I think this is what i have to do. Up until now I haven't used any PMIX for flying the heli. I don't have the experience to fly inverted or thrash the helicopter like most videos show. I mainly would use flight mode N to spool up, flip up the gear switch to enable the Gov, then flip to Flight mode 1(to keep the throttle up so the TJ woul stay engaged) to do all my flying. Been quite a while since I poked around in the setup menus.

I'm up at work now, so I will read through your comment tonight and see what I can come up with. I think I'm headed in the right direction. I will post back with my results and answers to your questions in a couple of days. Weather here in Austin is not the best - gusty winds and rain\overcast.

Dave,

In this picture I have posted(I haven't began to move anything yet) I have the thottle lead from receiver connected throttle plug on the TJ.

aux2 from the receiver is connected to aux on the TJ

the beastx instructions tells me to connect single wire connectors to rudder, gear and aux1 on the receiver. The other end of that wire connects to the beastx

my connections differ slightly from your posted picture? does that help your thoughts?

thank you in advance!

Jason
