The Rocket Surpass range of brushless motors is precision-made using the latest manufacturing processes. The can is CNC machined from a solid billet of 6061 T6 aluminum, high-purity copper is used for the windings for improved efficiency, and oversized bearings are used for durability. The stator has super thin (0.2mm) laminations, and the rotor is then precision balanced for reliability, and ultra-smooth running at maximum RPMs.

The Rocket Surpass 3542-1250KV motor suits sport, scale, and 3D-type models. This robust motor suits LiPo batteries from 3~4S, and on test with a 4S battery gave 707 watts of power at 52A, making it a great motor for medium-size models. The motor is supplied with a machined prop adapter, complete with mounting bolts, allowing it to be mounted either way round.
