Available in 4in1 and ELRS versions

Here are the tips for you to choose 4in1 or ELRS, reviews by OscarLiang

"If you can’t decide between ELRS and 4in1, I’d probably go for the ELRS version. It’s going to be the major RC protocol in the near future as it’s so powerful and affordable, with a wide range of tiny and inexpensive ELRS receivers available.

One reason to get the 4in1 is if you only want to use other protocols such as Frsky D8/D16, but these are kind of obsolete and slowly phasing out. Or if you are buying an external ELRS module for the radio, then it also makes sense to get the 4in1 as you don’t want to have another ELRS module onboard doing nothing. An external ELRS module might have the advantage of higher maximum output power of up to 1W. But honestly the internal module’s 250mW is plenty for FPV pilots, giving you miles of range in ideal conditions. "

Optional V4.0 Hall Gimbals and AG01 Gimbals

V4.0 HALL GIMBALS

Standard version with V4.0 Hall Gimbals, same chipset as the AG01, optimized hall sensor circuitry, improves center point positioning and temperature stability. Stick travel, self-centering and stick tension are now externally adjustable.

Optional AG01 GIMBALS

AG01 Gimbal is fully CNC milled for ultimate precision with quad ball bearings for a smooth and precise feel. Featuring front-accessible tension and travel adjustment for easy fine-tuning.

Flat & Raised Grips Included

Both the raised and flat versions of the rear grips are included allowing you to customize the feel of your TX16s MKII right out of the box.

Built-in dual speakers

External Module Bay
