3500Kv Outrunner Brushless Motor

490 Watt Ducted Fan Motor for 4 Cells

28mm diameter, 63mm long (excluding 10mm shaft), 3mm shaft, 3.1 oz, 3500 Kv. Motor comes pre-connected with 3.5mm male connectors. Design has cooling holes at the front and a ventilated aerodynamic rear section for good cooling and drag reduction. This is the replacement motor for our Su-34 and F-15 jets. Fits our 64mm fan (HLI34360710) and will produce more than 2.2 pounds of thrust when mated to a 4-cell lipo battery and a 45A controller. Actual current draw is about 33A on 4-cells. Front mount is 20mm dia. with 4 mounting holes on 16mm centers. Requires 4-2.5mm screws (not included). Rear mounting ring is about 24mm dia. and stabilizes the motor inside the fan. The main part of the fan remains in the cooling air stream.
