[. . . ] The rear motor cover is equipped with three connectors 3. 5mm in diameter for connecting the motor to the controller. In case the used controller is fitted with connectors of different diameters, or its female connectors do not adhere firmly to the motor connectors, replace them with those supplied as motor accessories. Use of incorrect connectors may cause damage to the motor and controller. Replace any two supply cables if the motor rotates in the opposite direction. Use high-quality chuck adapters of 4mm inside diameter for gripping the propeller. If an unsuitable or poor-quality adapter is used, the rotating propeller may slip off and cause serious injury. Drive Optimisation By means of correct choice especially of propeller, accumulator and controller parameters it is possible to change driving unit properties within wide range and thus flight behaviour and attained flight time. Use data mentioned in tables as guidance for your decision-making. In case other propeller is used than that mentioned it is necessary to check max. Use the controller that will supply current values mentioned in specifications with reserve. We recommend use of the 22 ­ 44 A controller (depends on the motor type). The regulator advance should be set to 20-25° or higher and frequency to 8 kHz. As to supply accumulators do not exceed max. discharging currents because there is a danger of destruction. Do not overload the motor unnecessarily because there is a danger of damage or deterioration of performance parameters. If the motor operates within the range recommended in technical specifications, its lifetime is limited by mechanical endurance only. Suitable combinations of propellers and supply sources ­ see the table "Area of application" Motor Maintenance AC electric motors are not maintenance-demanding. The same applies to MVVS motors as well, as maintenance only involves keeping the motor in dry and clean condition. If no accident happens, motor service life is only limited by lifetime of bearings in hundreds of hours, depending on flying style and loading. Wear of bearings shows by increased noise and radial allowance. [. . . ] Check attachment to the motor bed regularly. Immediately replace damaged propellers or propellers that touched the ground!Never stand so that parts of your body are in the plane with the rotating propeller. Apply the same principle for bystanders. [. . . ]
