Instructions Piccolo Brushless Set
Remove the brushed electric motor, but leave the white motor connector hang free from the Piccoboard, as
it will not be used anymore for the Brushless Set. Before you mount the brushless motor, you will have to re-
move material from the Piccolo chassis to allow for enough room to be able to adjust the gear mesh properly.
Now mount the motor to the chassis and make sure, that the three motor leads are on the right side of the
helicopter.
Connect the male connectors of the motor with the female connectors of the controller. At this point the con-
necting sequence is of no importance. Should you realize during a test run, that the motor runs reversed (it
should run clockwise) you may switch any two of the three leads. Connect the 3-wire lead of the controller
and the 3-wire lead of the Piccoboard to the included Y-adapter and this adapter to the throttle channel on the
Piccoboard receiver. Pull the center lead (red) of the controller lead out of the plug and insulate it (electrical
tape), as it will no longer be used and would only cause interferences.
Now connect the battery leads of the Piccoboard and the brushless controller to the JST Y-adapter to supply
both components with current. The last step is to mount the controller to the chassis by using double face tape
or a tie wrap. Secure the controller as shown in the photo below and make sure, that none of the leads can
touch any moving components such as the main gear.
Before flying your Piccolo, you will have to program your controller first (follow the instructions of the brushless
controller). When programming ALWAYS remove the motor pinion to avoid inadvertent operation of the main
rotor system.
