Centre both servos and attach horns and clevises. Insert into the rear of the plane as shown
below.
Make sure that the servos fit as deep as possible in this slot, but still move freely without the
clevises rubbing against the fiberglass. Try to visualize where the thrust tube will eventually
reside and make sure that there will be enough clearance between the clevis and the tube.
Alternatively, flip the pushrods and use the Z bend in the servos and attach the clevises to the
control horns.
