Description: The Holybro FETtec FC G4 features the latest STM32 G4 MCU with math accelerator for the ultimate in-flight performance, onboard OSD for KISS flight tuning, 2 dedicated BECs for 5V and 16V switchable power, DSHOT2400 outputs for support of up to 8 motors, and dual 20x20 and 30x30 mounting holes.
Note: Currently, the Holybro Fettec FC G4 does not support BLHeli_32 ESC Configuration via FC Passthrough and BLHeli_32 ESC telemetry/current reading. An Betaflight Flight Controller is needed to configure BLHeli32 ESC Setting.

Tekko32 F4 Metal 4in1 65A ESC
F4 MCU @150Mhz / Metal-Cased MOSFET / PWM output up to 96K / 4~6S / BLHELI32 The all new Tekko32 Metal is the first 4in1 ESC in the market to adapt the fast F4 MCU. Powerful & reliable metal-cased MOSFET 4in1 ESC with smooth control and quick response.
Features:
New & faster F4 MCU @ 150Mhz (compared to F3 @108Mhz & F0 @48Mhz)
PWM output up to 96K (default 48K)
Metal-cased MOSFET for excellent heat dissipation
Massive on-board capacitance for noise filtering at 2068uf
3 oz copper PCB design to allow bigger current and better heat dissipation
Separate drive & control circuit, this broadens the current capability of the drive circuit while reducing the electrical interference to the control circuit.
Specification:
Continuous Current: 65A x4
Burst Current: 75A x4
Supports 4-6S battery
Supports DShot 150/300/600/1200 & MultiShot/OneShot/Proshot/PWM etc.
ESC telemetry Supported
Onboard analog current sensor
No output BEC
BLHeli_32 firmware
1000uf 35v capacitor included (highly recommended for 6s setup)
Air flow for the ESC is very important if you want to run this 4in1 in high current. The battery wire (from Lipo to 4in1 ESC) should be at least 12AWG and well soldered.
I really like this radio but I had a gimbal stick pull out without any pulling on it. I've had this happen with other name brand radios so it's not a surprise or let down. A little super glue and right back at it. It feels great! I love the full sized gimbals! I have the zorro and the boxer but I think this one is the right fit for me.
Handy as a second transmitter for travel, tiny whoops, etc
Surprisingly good for the price especially with ELRS. It has just enough switches that I can do most of what I can with the TX16S, and it's so much easier to throw in a bag and go. My only wish is that I could put the thumb-grippies style of stick ends on it easily (and still remove them for storage), but maybe someone will come up with an adapter or similar. Next step is to try a Gemini ELRS nano module and see what kind of range is possible on that.
