Overview and Specifications:


Mode 2: left hand throttle

the T12 version does indeed support Crossfire and in CRSF mode with LUA script support
and most importantly WITHOUT any hardware modification for end users.
The T12 platform is shipped with the JP4-in-1 Multi-protocol module.
such as the TBS Crossfire or any other compatible 2.4ghz JR Module, Analogue or Long Range UHF system,
the T12 is ready to rock out with its socket out!
A standard LCD screen was used along with the T8SG V2 butter smooth V2 gimbals.
The T12 comes standard with a neck strap and AA battery tray.
Can also be powered with any LiPO or LiFE battery of a compatible size.
( Which means that users do not need to source their own uncommon sized Li-ion round cells or a round cell charger.)
The T12, when paired with the Jumper JP4-in-1 offers seamless intergration between the OpenTX software and module
meaning protocals can be accessed and selected directly from the software GUI.
Crossfire users can setup their equipment via the OpenTX LUA scripts.
