4pcs/lot BETAFPV 1606 2550KV/1550KV 4-6S Brushless Motors with 1.5mm Shaft Diameter for 4-5 inch Toothpick RC Quadcopter

1606 series motor is a smooth running, high-quality lightweight 4-6S motor! The 1550KV version is suitable for 6S power systems, and the 2550KV version is ideal for 4S power systems. Combined with high-quality 35A AIO Brushless FC, it will give your drones a strong power to fly more flexible and more durable. Highly recommend using it for the 4-5 inch Toothpick Quad, such as TWIG ET5, TWIG Mutant 4'' and X-Knight 4'' FPV.

Bullet Point

• 1606 motors are more durable, which will give you a longer flight time. 1550KV is a 6S motor, you can get 5:30-7:00 flight time in 4-inch quadcopter and 2550KV is a 4S motor, you can get 4:10-6:40 flight time in 4-inch quadcopter. 
• Both of 1550KV and 2550KV version motor only weight 15.17g for 1pc, for the weight-sensitive drone fans, this is a better choice for you to DIY your own toothpick quad.
• Suitable for the 4-5 inch Toothpick Quad, we recommend using 5125/5020 propellers with the motors to get the excellent power effect during your FPV racing.
• It retains φ1.5mm shaft design instead of thread shaft for saving weight, which means it needs M2 screws to lock props, while most of 4'' props are locked with nuts in the market.
