T12 Jumper T-12 "how to" discussion

Well, I just got the Jumper T12 with the multiprotocol Module. I was able to get started in only the simplest functions. I'm reading posts, taking notes and watching Youtube video but I have a lot of questions and I don't see or understand the answers. I'll try to ask and take questions and post answers in this original post/blog. I'll even break down the points I've already learned below or direct you or I to a video or post with the answers or details. I'll see how it goes from here.

1. Youtube video's and reviews explain the basics.
minutes 5 to 12:30 buttons and basics

Jumper T12 OpenTX Transmitter Review �� (29 min 53 sec)
  • How to choose and install battery. A 2s Lipo seems to be best. I got a 2000MAH 2S from E-bay but it required a slight internal battery case mod to get it to fit. link here soon
  • How to turn on/off.
  • How to use the keys.
    ENTER and EXIT on left. (ENTER has long press option in some cases),
    on right UP and DOWN, MENU and PAGE MENU forward , (page back is long press PAGE MENU forward)
  • How to get int the RADIO MENU and the MODEL MENU.

Q. How to change / reverse servo or direction.
A. in the MODEL MENU pg. 7 locate the one to change, short press ENTER, then EDIT, go DOWN to DIRECTION, press enter to toggle INV, then press EXIT twice to get back and change more or exit again to complete.

There is a 2nd way to change by running the numbers from minus (-)100 to 100 and 100 to minus (-)100 but that seems to take a lot of time.

I be a beginner and got a Jumper T8SG Plus v2. I'm a linux type person and was able to figure out loading model files and changing parameters. I do not know diddly squat about mixing parameters and don't have the slightest idea how this is done. Modifying others files can be done and is more intuitive than Open Tx. The Deviation manual is Greek (figuratively). The Open Tx is Chinese (figuratively harder). I got a T12 and am glad I didn't spend money on the Hall effect gimbals. Talk about confusing, sheesh. I thought Open Source would be pretty intuitive.
I guess not. I have a model file I'll have to try to get into the T12 and I appreciate the files above. Perhaps I'll change my tune after I go through the files above. Kurt

It would be great to make a step by step procedure setup ( what and why ) for all people ( new bees ) that has no experience at all with OpenTX and with this TX
Radio setup ... Model Setup like frsky receivers ( D8, D16, ... )

First of all be sure to follow the instructions of what to put on the SD card. Using the SD allows you to create a model using what's called a WIZARD. This wizard will setup most of the beginning parameters autoMAJICally.

Anyone got the dimensions to the battery compartment for the T12? Or the measurements for a lipo or life you are using that fit fine?
