For info, I have tried all the master-slave combinations between the the various transmitters I have.

I wanted to let my son fly in trainer mode tomorrow morning, but now I may have to risk handing him the single transmitter.If you remove the tx module from the student transmitter, it is my understanding that the 2 9xs will work in buddy box mode without any hardware mods. To download the video, you must first provide the video’s URL or web page link and then choose the appropriate format and resolution. Channel 1 will now be set to output from the aileron stick on the master, but from the channel 2 from the student if you switch the TRN switch.

Cross-platform support, scheduled downloads, audio extraction, proxy configuration, fast download speeds, video conversion, bulk downloads, and more features are available. This is less flexible than the previous method as you have to configure expo and mixing for the student inputs to match the master controls. I'm sure the anwers are on this forum, but each thread contains dozens or hundreds of pages, makes info a little hard to find. What does happen is the BL does not light unless the power switch is on and this is not done when it's a trainer TX. Thought I would post these in case any of you have an intimate knowledge of the 9xr pro and can observe anything that looks out of place with my particular model….I can say for sure that the 9XR and 9XR Pro work well in the buddy box role and are very good all round transmitters. Justo antes de completar tu primer pedido, tómate un momento para comprobar los cupones que tienes, con ellos te ahorrarás aún más en 9 x buddy. That's my initial guess… Im just uploading a video to vimeo to post here and see if you guys might be able to help me get this thing working. Guess I'm wondering if I would then have to crack open the 9xr pro and start soldering that too, to get them to work.
