Product overview
The YAHREE JT2826 KV1100 is a brushless propulsion motor for fixed-wing aircraft and VTOL UAVs, including F3A and 3D airplanes. Its 12-slot, 14-pole construction incorporates a long shaft, mounting cross, triple-bearing system and hand-wound coils. High-temperature-resistant arc magnets and insulated enameled wire are additional construction features. The motor measures 35.2+/-0.10 mm in diameter and 47+/-0.4 mm in length, with a weight of 168+/-5 g. It is an aircraft propulsion component; the ESC and propeller specifications describe equipment for integration.
The 1100 KV configuration recommends a 3S–4S LiPo battery, 2S–6S/80A ESC and 12×6 propeller. Compatibility also includes a Fixed Wing 60A ESC and fixed-wing 12-inch propellers. Maximum continuous current and power are 55 A and 632.5 W at 11.5 V; the 75 A and 862.5 W maximum is limited to 15 seconds. Thrust varies with propeller, voltage and test conditions: the 12×6 performance data reach 2390 g at 100% throttle and 10.9 V. Aircraft guidance spans 1.5–2.2 kg, with an optimized takeoff-weight range of 1400–1600 g.
