manufacturer. Propeller is mounted on motor by a central bolt M10x 1 and six screws around the

perimeter of the flange.

5. First start of the motor

Properly attach the motor to the model or the test stand using all four screws. We don´t recomended

long running on stand due to vibrations, which is another than in case of mounting in the fuselage. If

you use testing stand, do not screw the engine hard, for example on a steel weldment, but always

use at least a wooden board, etc., but not the silentblocks! Connect the ignition source (4.8 - 9V, min.

capacity of 1500 mAh). Connect the fuel tank.

If after about 5 attempts, the engine does not start, repeat the procedure again

Note : ignition is equipped with a security protection function, because if it is turned on and the

motor is more than a minute at rest, the ignition is switched off. In this case, it is only the ignition off

and on again. For more information see the instructions of electronic ignition.
