Buddy Boxing

[Pinecone]

I was trying to set up my X9303 and XP9303 to buddy box on my Vibe.

I set the X9303 as Master. The XP9303 as Slave. I used a stereo cable (mon would not do anything).

I started with a blank memory on the Slave, but when I hit the traine switch on the Master, the throttle worked backwards and the left front servo went full throw. Same thing if I copied the Vibe setup to the Slave and used that memory.

Reversing channels on the slave didn't do anything for the main channels, but I could reverse the Aux and get the Switch Glow from going into glow power on mode.

Any ideas on how to make this work?

Just tried it with a plank and everything worked right, except the elevator. And reversing the elevator on the Slave did not change anything.

Very wierd.

Set the trainer mode on the slave radio to [slave= p-link]
set master radio to master [p-link]
should work.

[rockjock3]

Yea. Reversing the slave controls should do nothing. The master is the radio that settings are drawn from. When I fly buddy box with a friend (just twice so far) he actually flies master with my radio (all the settings for my heli) and I fly with his radio (same radios).

[WayneBrown]

You can always copy the model into the slave radio given that the radio offers a PPM modulation. On two similar units, using the p-link should override the modulation settings in the slave.

[Pinecone]

How do you put an X9303 into P-link mode?

In Trainer I have the choice of Master or Slave only.

We just did this ALOT suddenly at our field. We used a mono cable and the following steps to "transfer" a copy of the setup to the slave radio. (neat stuff)



Power + on for both radios
Select model on the 'master' radio
Select empty model slot on 'slave' radio
exit model select screen and select "transfer" screen on both radios
"Master" radio sets up to do a "Transmit", insert buddy cable, turn off power switch (radio will stay powered up)
"Slave" radio sets up to do a "Receive", insert buddy cable, turn off power switch (again radio stays power up)
finally, slave hits the "start" button to receive the setup file, while "Master" hits start to Transmit setup file.
Magic happens

At this point, diconect buddy cable, turn radios off



Master turns on his radio and model, makes sure controls work.
Master plugs buddy cord into his radio (nothing happens)
Slave start with power OFF, plugs buddy cord in (his radio turns on auto-magicly)
Master holds trainer switch and slave tests his control over the model

Neat thing with this is the model name, switch assignments, trim, and mix settings make it over (coolest thing I've seen in a long time)

One of the heli elders had a plank kit and parts, I had the time to assemble and build, and since then we (the heli freaks at the field) have taken turns buddy boxing on the heli beater fixed wing. (Mostly I think the fixed wing guys find it disturbing the heli guys are "learning" on a Great Planes Reactor 70 3D (a third or fourth plane I'm told)

I cannot get mine to transfer ANYTHING with a mono cable.

I transferred all my models over from teh XP to the X in teh first place with a stereo cable.

If I try to do the Trainer thing with a MONO cable, the Master never transfers control. It seems like it doesn't see itself as a Master.

I wonder if I need to send it to Horizon?

[WayneBrown]

you need a stereo 1/8"cable if I remember correctly.
plus you gotta be quick with the button pressing. :)

[Pinecone]

OK, FIXED.

I called Horizon/JR. :)

In complete disagreement with the manual, to buddy box two 9303s:

1) Copy the model from the Master to the Slave, I have to use a Stereo cable. Both Txes OFF. When you plug into each one, you have to hold the top button to go into the menu where you can select the model. On the Slave, go into Transfer and select Receive. You can then select the model memory you want to save into on this screen. You cannot save into athe active model memory, so you may need to go to Model Select and change what is the active model.

On the Master, you have to select the model you want to transfer as the Active model, then go into Transfer and it should be in Send. If not select Send.

Hit the approprite button (read screen. IIRC the second from the bottom) on the Slave to put it in receive mode, the screen should say StandBy. Hit the same button on the Master and you will see it send, the percentage sent is on the right. The Slave should be showing the same amount recevied.

If you want to copy more, then select the proper memory on the Slave on the Transfer screen (NOT as the Active model), and the proper model to send as the Active model on the Master, and repeat.

2) Now that the model is copied, you turn on the Master Tx (turn on with top button pressed to select the proper model if needed). Plug the trainer cable into it (I HAVE to use a stereo cable, no matter that the JR trainer cable looks to be a mono cable).

3) With the Slave OFF, plug the trainer cable in. You can either turn it on with the top button pressed and select the proper model then turn off, or you can hold the button when you insert the cable.

4) DO NOT CHANGE THE SLAVE TO SLAVE IN THE TRAINER MENU. LEAVE IT ALONE.

5) The Master will control the model when the trainer switch is back, the Slave will control when it is forward.

It seems that all the 9303s have the older firmware without the cool P-link setup that the DX7 (and parent 7202) have. So you have to have both radios programmed to the model as the slave is sending everything (mixes, trims, curves, etc.) to the Master, which only transmits them. So this also seems to mean, if you have a JR 9303, you cannot use a simple cheap buddy box as the Slave.

[JimLerch]

Odd, the cable I use to connect my X9303 to my computer is a mono cable. I'm 99% certain the buddy box cable out at the field in mono as well.

I Will need to test the 6i slave with x9303 as master..... (insert time)

OK, just got back from that test. Short answer is YES, the DX6i slave to X9303 works, but you have to go to the trainer menu in the 9303 and set the 4 channels to "Slave." If you don't, things like split ailerons / elevator wont work.

So, 9303 to 9303 you need to Transfer the model, and leave the trainer menu with all channels on Master. The slave will be the unit with the power switch off.

DX6i to 9303, no ability to transfer model data, and you only get 4 channels for the trainer (slave) to play with.

At least it works..

BTW, I did use a stereo patch cable between the DX6i and 9303 as I couldn't find a mono cable.. If I find a mono cable, I'll retest.

Also, I know a DX6i -> DX7 works, So I'm going to assume a DX7 -> 9303 will work the same way.

I'd also guess, any Tx and a proper cable could be used as the slave with a 9303, but I'd love to know for certain.

Actually, I do this all the time. JR Quattro as slave, JR 8103 or 9303 as master. Works fine, even with CCPM helis. I'll check and see how I have it set up.

[Pinecone]

Please do. Because 9303 to 9303 it doesn't work that way.

And 6102 to 9303 doesn't work either.

I've done this with a DX7, set the DX (slave) as P link Slave.
it should read the settings from the 9303 and all should work correctly. It's been awhile, but it has been done by me.
