Step 2: Open it up
Step 3: Drill
Essentially, you should drill the holes in such a way that they create a square on the backside of each opening.
Step 4: The first motor
Insert the first motor into the handset opening that is on the opposite side of the jack, in such a way that the horn is facing inwards.
(The horn is the gear-like object attached to the servo shaft)
Step 5: The second motor
Zip tie them both in place using the holes that you have drilled in Step 3.
