Product overview
The SF2306 is a brushless motor for RC aircraft propulsion in an FPV racing motor range. Its applications include DIY quadcopters, helicopters, racing aircraft and fixed-wing models. Two variants, 1750KV and 2500KV, have operating data for specific battery and propeller combinations. The 1750KV configuration uses 7×4E propellers, while the 2500KV configurations use 5045×2 or 6040×2 propellers. Both variants have operating points at 16 V with LiPo ×4 and at 20 V with LiPo ×5, tying their pull and electrical demand to the selected arrangement.
For the SF2306 1750KV, an operating point with LiPo ×4 / 7×4E at 16 V gives 1050 g pull at 21.8 A and 348.8 W. With LiPo ×5 / 7×4E at 20 V, the corresponding higher-pull point is 1250 g at 26.5 A and 530.0 W. The 2500KV variant has a 20 V operating point of 1480 g pull at 32.8 A and 656.6 W with LiPo ×5 / 5045×2, and 1580 g at 35.2 A and 703.0 W with LiPo ×5 / 6040×2. These figures describe individual motor operating points under the stated conditions, rather than aircraft payload ratings.
