Product overview
The GEPRC SPEEDX2 2105.5 is a brushless propulsion motor for 3–4-inch whoop FPV aircraft and 4–5-inch toothpick and long-range FPV builds. Its flat motor shape and hollowed rotor top are intended to improve heat dissipation. The 2450KV, 2650KV and 3450KV versions share a 12N14P configuration, N52H ARC magnets and a stator measuring 21mm in diameter by 5.5mm high. Each weighs 21.0g and measures Φ25.65mm × 15.7mm overall, defining the motor's physical envelope for installation.
Mechanical integration uses a 12mm × 12mm mounting pattern for M2 screws, 150mm 22#AWG leads and a shaft specified as Φ3.0mm(in)Φ1.5(out). The 2450KV and 2650KV versions support 3–6S LiPo batteries, with maximum continuous power of 507W and 559W; their maximum currents at 5S are 31.7A and 34.9A respectively. The 3450KV version supports 3–4S, with 558W maximum continuous power and 34.9A maximum current. The package supplies one motor, five M2 × 6mm screws and five M2 × 7mm screws.
