Description

The EMAX Mini Magnum 2 Flytower consolidates core flight electronics into a single, robust 20x20mm mounting package. Its F4 flight controller, powered by an STM32F405 MCU and an MPU6000 gyro connected via SPI, delivers stable, low-latency processing for Betaflight or ArduPilot firmware. The integrated 5V/3A BEC provides clean power for peripherals, while the on-board OSD allows for in-goggle telemetry display.

The 35A continuous-rated BLHeli_32 4-in-1 ESC is built with high-quality MOSFETs on a 3oz PCB, capable of handling the high current demands of modern 5-inch 6S setups. The ESC’s physical footprint extends to 37x32mm to accommodate large capacitors for clean power delivery. The integrated VTX operates on standard 5.8GHz bands, is FCC compliant, and features TBS SmartAudio for convenient channel and power switching directly from your radio transmitter.

Key Features

  • Unified Flytower Design: Pre-assembled stack simplifies wiring and reduces build time for 20x20mm frame compatibility.
  • High-Current BLHeli_32 ESC: 35A continuous (40A burst) rating with support for DSHOT, MULTISHOT, and ONESHOT125 protocols on 2-6S LiPo.
  • High-Performance F4 Flight Controller: Features STM32F405 MCU, MPU6000 SPI gyro for precise flight control, and integrated OSD for telemetry overlay.
  • SmartAudio VTX Integration: Built-in 5.8GHz video transmitter with 25mW/200mW selectable output and MMCX antenna port, controllable via TBS SmartAudio.
  • Robust Power Delivery: Includes an on-board 5V/3A BEC and large low-ESR capacitors on the ESC for stable voltage under high load.
  • Compact Yet Capable Footprint: 20x20mm mounting pattern with an expanded ESC baseplate (37x32mm) for enhanced thermal and electrical performance.

Applications

  • High-performance 5-inch FPV racing drones requiring a compact, powerful 20x20mm stack.
  • Freestyle quadcopters running 4S to 6S LiPo batteries with high-KV motors.
  • Compact 3-inch to 4-inch micro builds where space is limited but 6S power is desired.
  • DIY drone projects seeking an integrated solution with FC, ESC, OSD, and VTX to minimize wiring.
  • Builds utilizing ExpressLRS or Crossfire receivers for long-range or competitive racing.

Frequently Asked Questions

What is the maximum recommended motor KV for 6S use with this stack?

EMAX specifies a 1700KV motor limit for 6S operation with the Mini Magnum 2 stack. Using higher KV motors on 6S may exceed the ESC's current and thermal capabilities. For 5-inch builds on 6S, motors in the 1700-1900KV range are typically well-suited.

How do I control the VTX settings?

The integrated VTX supports TBS SmartAudio. Connect the SmartAudio wire from the flight controller to your receiver's telemetry pad, then configure the VTX table in Betaflight. This allows you to change channels, power levels (25mW/200mW), and band directly from your radio transmitter's menu.

Is the 20x20mm mounting pattern compatible with all 20x20 frames?

Yes, the stack uses standard 20mm hole spacing. However, the 4-in-1 ESC board has a larger physical footprint of 37x32mm. Ensure your frame has sufficient clearance below the stack to accommodate this larger baseplate and its components, such as the capacitors.

Does the flight controller support ExpressLRS receivers?

Yes. The F4 flight controller has dedicated UARTs for serial receiver protocols. You can wire an ExpressLRS receiver to any free UART RX/TX pad and configure it in Betaflight using the CRSF protocol. Ensure you provide 5V power from the flight controller's BEC.
