Use for each motor plate 2 pairs of clamps, 4 m3 washers, 2 motorplate
position plates, 4 m3 x 35 bolts and 4 m3 locknuts, just tighten them
with your hands
Now you can mount the motor plates to the tube, and put the endcap
in the tube, just like on the picture, make sure your cables are
connected inside the tubes correctly or make sure the cables are
long enough to reach your esc. At this point you can tighten the
bolts. Do not overtighten the clamps can break when you over
tighten them a lot. Make sure the clamps are closed to eachother
left and right the same.
