Figure 3-9. This is what our PDB looked like—we tinned a few
solder spots and added liquid tape for a layer of insulation.
Now press the PDB into place in the middle of the dirty frame
where it will be easily accessible by the battery lead, ESCs, and
any extras that need access to power (see Figure 3-11). There is
a 3-mm hole in the middle if you would like to also add a screw
for extra support. We found that the double-sided tape did a
very good job holding it in place and opted to not use one. If you
do use a screw, try using a small nylon screw and nut, which will
save on weight and also does not act as a conductor.
