Next, screw the 4 motors onto the ends of the carbon arms, using the M2 nylon screws. Orient each motor
on the frame so that its wires are directed inward at a diagonal angle (Photo 2), and insert the screws from
above. Note that the carbon is drilled for more than one type of motor base plate, so there are some extra
holes.
Take care not to bend the motor wires right where they join to the motor, because they can be
damaged.
Fasten each screw with an M2 nylon nut under the carbon, and tighten
gentle finger tight only
.
Once all 4 screws are in place, add a second nut to each for reinforcement (Photo 3). It is crucial not to over
tighten the nuts, otherwise the screws will be damaged. Although metal screws would be stronger, the nylon
screws will pull out in the event of a crash, usually preventing damage to the motor or carbon frame. They
also save significant weight.
2)
Attach the 4 motor speed controllers (ESCs) to the carbon arms, using the black cable ties provided.
There are two holes in each carbon arm, to thread the cable tie through. The ESC should be oriented
with the red, black and yellow wires directed outwards towards the motor, and positioned just outside
the inner black spacer post (Photo 4).
3)
Next, connect the motors to the ESCs. There are three connections to make for each motor, and the
connectors simply plug together. After making the connections, fold the wires neatly and fasten them
with a cable tie (Photo 5).
Make sure that the motor wires are not rubbing on the silver rotating
part
, especially the black section where the wires join the motor (see Photo 23 on page 16).
