This is a re-edit of the original review video. I have removed mentions of "Dual LR1121 chips" because the TX15 uses a single LR1121 RF chip and does not offer GemX protocol.
Specifications
Item: TX15 Max Radio Controller
Size: 178*168*81mm
Weight: 672g (without battery)
Color: Red/ Black/ Gold
Frequency: 2.400GHz OR Sub-G 900MHz
Internal RF: ELRS 2.4GHz / Sub-G 900MHz
Supported Protocols: Express-LRS
Cooling Fan: Yes
Transmitter Module: Built-in ELRS
Built-in Flash Size: 4GB
MicroSD card* (Not included): 32GB/FAT32 (Inserting a MicroSD card will disable the onboard flash)
Antenna Gain: 2dB (transmit power adjustable)
Current: 875mA at max power output
Voltage Range: 6.6 - 8.4V DC
Radio Firmware: EdgeTX (Transmitter) (requires version 3.0.0 or later)
Module Firmware: ExpressLRS
Channels: Max 16 channels (Receiver dependent)
Display: 3.5-inch IPS touchscreen (480 x 320 resolution)
Battery: 7.4V 2-cell Lithium-Polymer / Two 3.7V 18650 Lithium-Ion cells / 21700 5000mAh Battery (batteries not included)

With the latest TX15 firmware the internal gyro is enabled. This means TiltX / TiltY can be used as a channel source. It can be used for things like pan/tilt of a camera etc. You can use offset to change the center position and curves to make a deadband at center etc. It can also be used to trigger logic switches, for example tilt in a certain direction to call out a telemetry value etc.
