V-tail Frame for the Hubsan X4 Quadcopter

V-Tail quad-copter frame using the Hubsan X4 board. All motors were upgraded to 8.5mm coreless motors. It has a very sharp and responsive Yaw control.

Stock props can provide enough lift but only at 80% throttle. Exchanging the back stock props with bigger ones will improve the performance. My current setup is listed below:

• Front prop: Stock props
• Back prop: YD717 props
• Board mounts from the bottom of the frame
• Back motor wires may need to be extended to reach the board

Additional Information:

• Tilted (dihedral) front motors: 5° to the center
• Front wing angle: 150°
• V-tail angle: 120°
