Product material: plastic Product net weight: 22g Product list: tail wing*1, indicator card*1 Product color: gray Product gross weight: 41g Product size: L82.61*W70*H71.43mm Lock the battery to prevent it from falling off Prevent the for FLIP battery from accidentally loosening during flight, accurately protect the battery, and prevent the battery from falling off, losing, scrapping, etc. due to accidental impact. Accurate positioning and firm installation Easy to use, just press the buckle to easily remove the battery. Aerodynamic design The aerodynamically designed tail wing can help the fuselage cut off the airflow to reduce air resistance. Bottom heat dissipation holes for fast heat dissipation The air holes reserved at the tail form a convection channel, which uses the principle of hot air rising to accelerate heat dissipation and accelerate the heat dissipation of the drone during flight. Lightweight design does not affect flight The tail wing is made of plastic lightweight material, weighing 229, and the tail wing shape design, which not only protects the battery after installation, but also beautifies the fuselage. Smooth lines, handsome beyond the sky The design of the tail wing takes full account of the characteristics of air flow, and reduces air resistance through streamlined design, thereby greatly improving stability. Anti-fall protection, landing buffer The tail wing not only provides stability during flight, but also provides buffering when the aircraft crashes and lands on its back, avoiding damage caused by loose batteries falling off during high-speed landing.
