The MultiStar Razor 40A Tower F4 is an excellent way of combining an F4 Flight Controller with 40A ESCs. This tower helps keep your drone or multirotor balanced as well as cutting down on ugly wiring. The boards come with standard 30.5x30.5mm mounting holes for easy installation in most frames.


At the heart is the F4 Flight Controller with an STM32F405 MCU for quick processing speed and an MPU-6000 SPI Gyro for a quick response. Couple this with Betaflight firmware for easy setup and configuration. The FC comes with integrated OSD and microSD card reader for saving flight and black box data. There are easy plug connections (cables provided) for connections to different types of receivers (SBUS, PPM, Spektrum), FPV camera, video transmitter, buzzer or LEDs with 3.3V, 5V or 12V power.


Connected directly to the Flight Controller is the ESC and Power Distribution Board with BLHeli_S firmware for superior throttle response. It supports Oneshot125, Oneshot42 and Multishot as well as Dshot150, Dshot300 and Dshot600. It also has a built-in current meter which displays directly onto the OSD. The 40A ESCs will provide all the power needed for most 170-450 multi-rotors.


This is an outstanding package for any drone or multirotor user and will get you set up and be flying in no time.

Really good FC

Aug 28, 2021

I have this FC in two 7" long range frames and one 5", I really like this FC.
One thing I can complain about is it is "plug based" FC not "solder pads" BUT it comes with lots of wires so it´s not a problem at all.

Really love this stack with 40A ESC 4 in 1. I have this stack on two 5" racer's, one 7" frame and currently building 450 mm frame with this stack.
One thing I would like better is direct solder on patches but you get tons of wires with plugs to get the setup done.

Good quality flytower

Mar 19, 2020

This is a very nice flytower set. It has a solid connection between ESC and fly board. No cables, but a direct connector. Great! I hate all those cables on drones. I have build this set in to a new drone and it flies very well.

Good FC

It is a very good F4 FC with a Powerful ESC and OSD. Only thing I m missing is a PWM Input for my old spectrum RX.

Connectors, makes the build fast and simple. It's a pinned stack, some might not like that. Love the current sensor and 40A is plenty for everything I fly. Had zero problems with both of the stacks I bought, I do wish it went up to 6S though.

Got this for my first build. It was very easy to install, and it came with all the wires needed.
Installed in a 220mm frame with EMAX 2205 2600kv motors. Three months in and its still working flawlessly!
