KAVAN PRO motors are high-performance brushless fourteen-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 4345-730
KAVAN PRO 4345-730 is an AC motor designed to drive models with a flight weight of up to 3000 g with power from a four- to five-cell LiPo battery. Great for models like our EPP "Warbirds" and 1300-1400mm wingspan aerobatic models, SIG's Smith Miniplane, etc.
Engine Mounting: The KAVAN PRO 4345-730 is designed for both front and rear mounting. For front mounting behind the engine face, use four M3 screws that extend 4-5mm into the engine face. The engine bulkhead should be 5-6mm aircraft grade plywood. The rear mounting kit (mounting cross, rear mounting propeller carrier) is supplied with the engine.
Motor kit includes: KAVAN PRO 4345-730 AC motor with cables with soldered 4mm gold-plated connectors, rear mounting kit. You can download the complete manual for the motor here: AC motors KAVAN PRO - Instruction manual
Note: Alternative designation according to stator dimensions 3520-730.
