KAVAN PRO motors are high-performance commutatorless (alternating, "brushless") fourteen or multi-pole electric motors with a rotating casing ("outrunner") with excellent electrical properties, sophisticated construction and top-quality manufacturing. Shafts made of hardened steel and high-quality bearings ensure a long service life, quality materials used for the manufacture of the stator and rotor also guarantee excellent performance parameters with high efficiency. They are low-speed, high-torque engines that handle large-diameter propellers and climbs without the need for a gearbox.

CAVAN FOR 7025-510
KAVAN PRO 7025-510 is a 28-pole AC motor designed to drive models with a flight weight of up to 5500 g and powered by a four- to six-cell LiPo battery. It is perfectly suited for models in which you would previously mount a 10-15 cc internal combustion engine.
Motor mounting: KAVAN PRO 7025-510 is designed for rear mounting; the mounting cross is an integral part of the engine. Use four M4 steel screws for fixing; engine bulkhead should be 6-8mm aircraft grade plywood.
Controller: When choosing a controller, be especially careful that it is a type designed to work with multi-pole motors (common controllers designed for 2-14 pole motors may not work properly).
Motor kit includes: KAVAN PRO 7025-510 AC motor with cables with soldered 4mm gold-plated connectors, propeller nut kit. You can download the complete manual for the motor here: AC motors KAVAN PRO 5050+ - Instruction manual
Note: Alternative designation according to the dimensions of the stator 6210-510.
