BM31 F22 Tail Fin Set Vertical Rear Tail Wings for Dual Brushless RC Plane

Restore Directional Stability, Eliminate Yaw Wobble, and Repair Crash-Damaged Tail Wings

A cracked, torn, or missing tail fin on your BM31 F22 Raptor RC Airplane severely destabilizes high-speed directional tracking and aerobatic maneuverability. Flying a dual brushless jet with damaged rear tail stabilizers causes erratic pitch and yaw oscillations, forces the 6-axis gyro system to overcompensate, and increases aerodynamic drag during high-speed stunt maneuvers. Attempting to glue deformed EPP tail foam rarely holds up against high airflow pressures and alters the jet's natural balance. This official replacement BM31 F22 Tail Fin Set completely resolves aerodynamic instability. Molded from high-density, crash-resistant EPP foam to original factory scale dimensions, it restores razor-sharp directional control, optimal pitch balance, and sleek stealth fighter aesthetics.

What’s in the Box

• 1 x BM31 F22 Tail Fin Set

Key Features

• High-Density Flexible EPP Foam: Crafted from ultra-tough, crash-absorbent EPP material designed to withstand high-speed impacts and resist bending.

• Factory Scale Stealth Profile: Engineered to match the exact aerodynamic curvature and twin-vertical-stabilizer profile of the BM31 F22 Raptor airframe.

• Optimal Gyro Efficiency: Provides clean airflow guidance across the tail section, allowing the onboard 6-axis stabilization system to work with precision.

• Lightweight Performance Build: Preserves exact factory Center of Gravity (CG) balance without adding unnecessary tail weight to maintain 360° stunt agility.

Installation Tips

• Removing Damaged Tail Fins: Carefully slice or detach the damaged tail fins from the rear fuselage sockets using a hobby knife, taking care not to tear the main fuselage foam body.

• Aligning Replacement Fins: Test-fit the new tail fins into the pre-molded mounting slots on the BM31 F22 fuselage to confirm a straight 90-degree vertical alignment.

• Applying Foam-Safe Adhesive: Apply a thin, even layer of foam-safe glue (or specialized EPP adhesive) along the insertion base tabs and press firmly into the fuselage slots.

• Pre-Flight Surface Check: Allow the adhesive to cure completely; inspect the tail assembly from the front and rear to verify symmetrical alignment before taking off.
