Offer the elevator servo into place on the underside of the hatch and temporarily hold in position
with the mounting screws. Fit the servo horn to the servo and mark the hatch where the pre-formed
slot has to be enlarged to allow full deflection of the servo arm – including trim range. Remove servo
from the hatch and use a Dremel tool or similar to open up the slot you have marked, Permagrit
tools are ideal to finish off the slot neatly.
Fit the elevator servo to the hatch, making sure all screws are completely tight.
Fit a suitable length extension lead to the elevator servo, it is highly recommended that a heavy duty
lead is used here due to the possible voltage drop due to the length of lead required. All extension
plugs and leads must be secured to each other during assembly, options include heatshrink tubing
over the plug/socket, vinyl tape, binding wire or one of the proprietary lead locks. Feed the
extension lead down the tailplane through the hatch aperture to the root. Screw the hatch complete
with elevator servo into place on the wing.
