======
I'm having difficulty setting up the training mode on two transmitters - a 9xr Pro (the student transmitter) and a 9xr (the trainer's buddy box)
Please correct me if my understanding of the scenario is incorrect.
We have a new flyer (me) who has a plane and a transmitter, but he's scared to fly the plane on his own because he knows he'll crash it. However, we have a good flyer on hand who offers to stand in as trainer. The student's transmitter is bound to the receiver in his plane, and the trainer removes his module, just so it can't get in the way of anything. As he can't transmit, we'll call his control the Buddy box.
The normal settings on the two boxes are ...
Code: Select all
Student Trainer - all his models use
1 Thr 1 Rud
2 Rud 2 Ele
3 Ele 3 Thr
4 Ail 4 Ail
The trainer then sets up...
Code: Select all
Dummy model
1 Thr
2 Rud
3 Ele
4 Ail
OK, so we go flying. The student seems hell-bent on doing a bit of ploughing, and the trainer decides he had better step in. He flips the trainer switch and takes control of the model. But it must surely be the trainer who has programmed into the buddy box which switch he wants to use?
I have been watching a video on setting up both controllers, and it seems that all the setup, even which switch to use, is done on the student's box.
I have been through the video several times, but I can't make it work. I think this whole exercise would be easier for me if I understood the mechanics of how it works - which box is doing the transmitting, and which box is programmed for training mode. The video at https://www.youtube.com/watch?v=gpu0lCbnynU starts off by saying "I'll show you step by step how to use the 9xr as a trainer" - but then it seems to me that he sets up the 9xr as the student box, because the other box doesn't have a module in it.
What is the principle? Does the trainer program into his buddy box the configuration of channels he will be controlling on the transmitter, or does the student do that, and the information is sent to the buddy box from the student's transmitter? I would assume the former, as the trainer may have whatever followed the stone tablet, and the student's 9xr pro should not make assumptions about the buddy box's abilities. One assumes, however, that the buddy box can be manually programmed. I assume that the student transmitter is the slave in this scanario, and the trainer's box is the master? And how do the two boxes know which is which? - Just by which one gets powered on first?
I'm pretty sure my cable is working, because when I switch the buddy box on and off, the calibrated signals in the student transmitter all change - but they don't change when I move the sticks on the buddy box.
There's a forest in front of me. Can somebody point out where the wood is?
