Also, apart from this, there is an English quick start guide that folds A4 paper, but it didn't say much.

Switch and antenna replacement / repairAfter using for about half a year, knob part of the toggle switch: SwG assigned to Arm suddenly fell off. So I bought 2-contact toggle switch from Amazon and replaced it (blue switch in photo). In the case of Jumper T12 Pro, switch with a size of about D8mm x W13mm x H10mm for switch body and diameter of 6mm for screw part fits perfectly.
Also, I dropped the radio and antenna broke, so I bought 2.4GHz whip antenna (SMA connector) from Amazon and replaced it. Total length of the antenna for 2.4GHz is different from that for 5.8GHz.
AG01 MINI CNC Hall Gimbal : gimbal replacementHere, We will explain the procedure to replace Jumper T12 Pro gimbal with AG01 MINI CNC Hall gimbal (RadioMaster) . However, this work can cause the radio to malfunction in the worst case. This site does not mean that we recommend replacing the gimbal. Please do it at your own risk.
This gimbal has been developed for over a year with engineers and FPV champion pro-pilots from around the world. All parts are CNC machined from aluminum, and ball bearings provide a smooth and accurate feel.
This gimbal is compatible with RadioMaster Zorro, TX12 series and Jumper T12 series. It seems that Jumper T8SG, which has the same body shape, can also be used.
However, in the Jumper T12 series, the chassis is thin, so the module bay interferes a little. Use a hot knife or similar to scrape off the contact area.
Gimbal is the key part of the radio. Flying FPV drones, in particular, puts a lot of force and abuse on the gimbal, so the all-metal AG01 gimbal is safe to use. The screw diameter of the stick end is 3 mm, the same as the original.
RadioMaster AG01 MINI CNC Hall Gimbals for TX12 & Zorro (RadioMaster)
If you want to install AG01 MINI gimbal on something other than RadioMaster Zorro, you need to attach the screw that comes with the gimbal to number 3 screw hole in the figure on the gimbal used for throttle in advance. For more information, please refer to "Installation for Zorro & TX12" on AG01 MINI CNC Hall gimbal product page (RadioMaster)
