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 55 ­ 65A controller. The regulator advance should be set to 20° 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. 6, 5 / 910 8, 0 / 680 Safety Instructions 1) 2) 3) 4) 5) 6) 7) 8) 9) 10) 11) 12) 13) 14) 15) Use the motor for designed purposes only. 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. Every accident may decrease bearing lifetime significantly. We recommend entrusting the manufacturer with replacement of bearings. If you decide to replace parts by yourselves, then always use original parts and MVVS tools only. Please note that there is necessary to hold the airspace between the fixing ring and bearing of 0. 1mm +- 0. 05mm, if you decided to disassemble the motor by yourself. Check regularly the screws of prop driver and fixing screws of they are tighten enough. Change the prop driver after the motor crash. There is recommended to exchange the shaft after the more serious crash. [. . . ] . Motor Installation into a model It is possible to mount the motors in two ways into the model. You can place the motor to the front of the model or on the motor firewall (to model originally intended for combustion engines). The mounting holes span you see on the drawing attached. In addition, drill at least 6 holes at least 8 mm in diameter for cooling air supply, so that to be positioned directly opposite to inlets in the face of the installed motor. [. . . ]
