Hello everyone,

Today I bring you the new version of the OMNIBUS F7 and the brand new Typhoon 32 4in1 ESC. For the specs this should be a perfect combo option, the very best and high performance micro-controller F745 ARM and the latest Blheli32 ESC firmware. I’ll divid this review into two sections, firts I’ll show you the flight controller and after the ESCs. So let’s see what we have here.


I’ll skip the unbox chapter because this FC came in a simple antistatic bag without any cables or connectors, all you get is the flight controller.

This is the revision of the first F7 version keeping the STM32F745 processor, just for the processor we know this will be a high performance flight controller. Plenty of power, this processor will let the developers to “spread their wings” of imagination, one of the downside to use this processors is his size, placed at the center of the FC it takes around 50% off the 36x36mm PCB size. This processors bring another great feature that we lost on the F4 flight controllers the capability to inverte the UART signal by software, so on F4 FC you only have one UART for Sbus because the other ones are not inverted, in this FC you can plug your receiver into any UART using the Sbus protocol. On this board you only get 4 motors output, 4 UARTs and one SPI or 3UARTs, one I2C and one SPI. The UART 7 is speacially used for the ESCs telemetry.

Unlike the first version this FC has over the huge F7 processor a system that soft mount both gyroscopes, yes Airbot introduced two gyros on this tiny PCB featuring the old and well known MPU6000 and also the ICM-20608-G a newer version of MPU6500, this last gyro has the capability to sample at 32kHz, much higher sampling than the old MPU6000 that sample only at 8kHz. Higher sampling isn’t allways a good thing, because can capture more vibrations and send this inputs to the motors causing even more vibration. So Airbot tried to soft mount the gyros to reduce the vibrations introduce by all the other things on the quad, like motors, props and so on. Besides we have two gyros on this board, we only can choose one at a time and not a merge of this two to work like redundancy.

This board also as a AB7456 IC for OSD and card bay for blackbox record, to power the VTX and camera you get a voltage regulator capable of 5V at 1A not so much amperage, but should be enough to power everything you need.

Typhoon 32:

This 32 bit ESCs are the brand new ESCs from Airbot they support DSHOT 1200 with BLHELI_32 firmware, support 3S and 4S lipo input, provide voltage output to the flight controller and have 30.5×30.5mm mounting holes. The package contains the ESC’s and two capacitors, one 2200uF and one 450uF. This ESC’s are fitted with 4 current sensors, one for each ESC, providing us 4 telemetry outputs (SWK) to connect on the F7 flight controller at the UART7. This feature allows us to configure at the OSD the ability to see the current at each ESC, but  we don’t know if the current sensor is calibrated or not and it’s not possible to configure. Mounting this ESCs on a quad is very easy, soldering it’s really easy and the PCB has the best quality I’ve ever saw in quad products.

At the beggining I had problems to put the quad on the air, problems not related with product but with the Betaflight firmware. The version 3.2 betaflight had some issues with the F7 flight controllers so I couldn’t ARM the quad so I took some time to finally test it. The latest version of the Betaflight already solved the protocol issues so now the communications with the ESCs can be made through DSHOT1200. I have to say that in the flight controller aspect the gyro ICM-20608-G don’t worth the try, I soft mounted the flight controller, the gyros on the FC are also soft mounted and I get vibrations on the flight, once I changed to the MPU6000 almost all the vibrations were gone. Everything else on this FC is working really good and the OSD built-in is defenitly a must.

The Typhoon 32 are loaded with many features and with the latest firmware, the form factor allow us to build a really clean quad, but the side power input doesn’t work very well in every frame, so my adevice would be to creat a newer version with the power input to the back and the motor output through the sides. At the moment I’m not using this ESCs because during the first flights everything worked really well, but after maybe 20 flights the ESCs started to desynchronizing and the motors warmed too much. I hope that my unit is a defective one, because it’s an unit a bit expensive and if bought it I would be very upset.

I want to thank to Airbot for the opportunity to test this combo.
