After determining the correct size drill bit, drill all of the pilot holes marked in the previous
step. Drill the holes completely through the stiffeners, doublers and keel. Mount the
servos to the keel as shown in Fig. 5-3 (note that the left/right cyclic servo is mounted on
the opposite side of the keel relative to the other servos) and install all servo mounting
screws. If any screws split the wood, remove the servo and apply a drop of thin CA to the
split area to repair the hole. Re-drill the repaired hole if necessary.

After you are satisfied that all servos are correctly mounted, remove them from the keel.
