EMAX F4 Magnum Six in One Tower System
  • Building a high performance FPV quadcopter for racing or freestyle has never been easier.
  • This tightly integrated systems packs the FC, ESC, RX, VTX, PDB, CURRENT SENSOR and OSD into neatly stacked boards that can be easily serviced or upgraded. The pinned board interconnects offer a clean wire free look and the compact stack can fit even the tightest builds with easy.
  • We have carefully combined some of the best FVP technology in our arsenal into a tightly pre-assembled package that offers the fastest way go from starting a new build to FPV Flight!
  • 6 in 1 Main Board – F4 FC + Betaflight OSD + LC Filter + 5v Regulator + Blackbox + Buzzer  
  • The heart of the flight control systems is a powerful STM32F405 MCU and MPU6000 gyro flashed with Betaflight for proven rocksteady flight stability. The integrated LC filter with 5v/3A voltage regulator means clean power for all the FC/OSD components and other attached boards such as VTX, RX and FPV Camera. Betaflight OSD with easily customizable layout of vital flight information and ability to change FC flight parameters. Blackbox flight log recorder with 16mb flash memory. On board buzzer for battery level warning or lost model finder functions.
  • 48 Chanel 5.8ghz Switchable Power VTX Board
  • VTX allows for easy change of VTX channel/band via push button.  Also transmit power is switchable from 25mw to 200mw. Included is a lightweight 5.8ghz dipole whip antenna or 80mm extension cable with SMA connecter for use with your own antenna.
  • Frsky XM+ 16ch Sbus Micro RX Board
  • Genuine FrSky XM+ receiver is included with 16 channels with RSSI. It possible to connect other brands of Serial or PPM via the dedicated RX pads.
  • Bullet 30A – 4 in 1 ESC + Current Sensor Board
  • The ESC system is comprised of 4 x 30A continuous Bullet ESC’s using top quality MOSFETs and running BLHeli_S firmware. Your choice of protocol: DSHOT, Multishot, Oneshot 125. The onboard current sensor monitors mAh consumed and pass the information to OSD for an accurate way to monitor battery level and peak power consumption.

    I’ve now built two Tokio X quads with this tower and in short, I love it. Fast build, well laid out boards, and the betaflight software is great. I especially like the built in OSD. My two gripes are the solder pads for the bat could be bigger and spaced apart, and the antenna mount does require Bondic to “glue” it to the board it its totally unusable. If you like a fast build, integrated components, and the ability to have an OSD in your googles including PID settings using your radio, get one.

    This is a great stack! It made for a quick build in an Alien Frame and was easy to configure and tune. It flies better than my KISS Alien. It is a much neater build too. Care must be taken to secure the video antenna with liquid tape to prevent it from snapping off. Also, be sure to protect the stack from twigs or crashes.
