MOFLY P-51D & MF-A84 690mm RC Warbird Replacement Receiver Board

The Brain of Your Precision Warbird

The receiver board is the central hub that processes your commands and maintains flight stability through the gyro system. Damage to this board from crashes or moisture can result in a loss of control or "unexplainable" flight behavior. This official MOFLY 690mm Receiver Board restores full 4-channel control and gyro stabilization to your P-51D or MF-A84, ensuring your aircraft flies as true as the day it was unboxed.  Ships worldwide.

Product Highlights

• Integrated 6-Axis Gyro: Features built-in stabilization technology that assists with leveling and wind resistance, making high-speed brushless flight accessible even in breezy conditions.

• FPV Camera Support: Specifically designed to work with the optional FPV camera and phone mount systems found on the MOFLY 690mm series.

• Standardized Port Layout: Includes clearly labeled ports for aileron, elevator, rudder, and ESC connections, making it easy to swap your existing components onto the new board.

Compatibility

This product is suitable for the following 690mm MoFly RC planes:

• MoFly P-51D 690mm Brushless RC Warbird (optional FPV camera & phone mount)
• MF-A84 690mm RC Warbird with Brushless Motor, Gyro & FPV Camera Support

Not intended for smaller 400–500mm models or larger 750mm+ warbirds unless clearly stated on the product page.

Install Tips

• Level Mounting: It is critical that the receiver board is mounted perfectly level and secure within the fuselage; if the board is tilted, the gyro will provide incorrect stabilization inputs.

• Antenna Orientation: Ensure the antenna wire is clear of other electronics and carbon fiber components to maximize signal range and avoid interference.

• Binding Process: After installation, follow the standard binding procedure for your specific transmitter to ensure a secure, interference-free 2.4GHz link.

Quick Q&A

Q: Can I connect my own ELRS receiver to the MOFLY P-51D Receiver Board and set up flaperons using its 2 separate aileron sockets?

A: Yes, it is technically possible via the board’s SBUS port, provided you configure the flaperon mixing yourself in your ELRS transmitter (EdgeTX/OpenTX).

The receiver board itself does not have a built-in flaperon mixing function—it simply passes through and gyro-stabilizes the two separate incoming aileron signals sent from your receiver. You must set up the custom mixing logic on your transmitter (assigning the roll stick for differential banking and a switch to deflect both ailerons downward as landing flaps). As long as you are familiar with setting up channel mixes on your ELRS radio, this setup will work smoothly.
