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.
Right away, this is the best 65mm Whoop I know. Not even close.
I ordered two, one is more or less stock, just the PEEK motor screws and V3 cockroach. The second is upgraded to 0702 27000kV but will go back because I like the 25000kV more because of smoother throttle response and perfect betaflight tune.
Now the but:
1. On both quads I had to replace the BeeEye for a spare one because both are out of focus.
2. the yellow props were way too loose and very brittle. I lost two on my maiden. Black, blue and red are very tight (too tight for such a fragile prop) but if you get them on without bending them, they will last.
3. why does the quad not come with the lighter frame right away?
4. PH2.0…. You know the drill.
On that price point, even after the frame and PEEK upgrade I can forgive these quality issues. Especially considering the great tune and quality FC and motors. But be sure to order a replacement cam and props right away.
This was kind of a late night lark. I'd seen this upgrade for the Mk3 for a while and pondered whether it was a gimmick or not, and I'm pleased to say it's a genuinely good upgrade. It has reduced the noise of my Mk3 considerably. I haven't noted any significant increase in print quality, but the old drone of the bed is gone and that's completely worth it.
