Precise details: GEPRC SPEEDX2 1303.5 5500KV 2-4S Brushless Motor for Cinelog25 Cinelog 25 DJI O3 FPV RC Racing Drone Summary: The SPEEDX2 1303.5 motor is an innovative brushless motor with a lightweight design, unique appearance and good heat dissipation. With a lightweight structure, only 6.5g (90mm cable length).The outer rotor uses a blade design, which is exquisite and magnificent. The raised propeller platform has greater compatibility with the inverted mounted propeller models, and avoids the contact between the large-pitch propeller and the top of the rotor to cause the propeller to be unbalanced. A large area is hollowed out to reduce weight, so as to obtain good heat dissipation and efficiency, and effectively control the working temperature of the motor. SPEEDX2 1303.5 motor is made of high quality 7075-T aircraft aluminum material, which brings better strength to the rotor. Good magnetic circuit design, with stable linearity and efficient explosive power, brings pilots a super smooth flying experience. Perfect for pilots to build their own 2″ cinewhoop FPV drones. GEPRC is committed to providing pilots with brushless motors that are lighter in weight, faster in response, higher in efficiency and stronger in power. Specifications: Model: SPEEDX2 1303.5-5500KVConfiguration：9N12P Magnet: N52H ARC Stator diameter: 13mm Stator height: 3.5mm Shaft diameter: Φ1.5mm(in)2mm(out) Dimension: Φ17.35mm*11.7mm Lead wires: 28 AWG 90mm Rated voltage (LiPo): 2-4S Maximum power: 128.8W Maximum current: 8.7A Recommended ESC: 35A Mounting hole: 9mmx9mm(M2) Color: titanium color Weight: 6.5g (90MM wire length) Suitable models: 2 inch with propeller guard drones or 2.5 inch freestyle drones Features: 1. 7075 aircraft aluminum one-piece high-strength housing makes the motor more durable and crash-resistant. 2. The small size and lightweight design makes the flight feel lighter. The weight with the cable is only 6.5g (90MM cable length), suitable for building a 2-inch drone with propeller guard. 3. Rotos large hollow design has a large air intake, and strong temperature control so that the motor runs more stable. 4. N52H strong magnet, with low internal loss stator, the efficiency is significantly improved, making the endurance more durable. 5. The 1.5mm shaft is generally suitable for conventional 2-2.5 inch propellers on the market. Package Includes: 1 x SPEEDX2 1303.5 motor 6 x M2*6mm screws 6 x M2*8mm screws
