To install the horizontal stabilizers you first need to install two 12” servo wire 

extensions in the fuselage so that they extend from the radio compartment to the aft 
openings.

．

There is an option to use one servo or two servos for the elevator. If using one 

servo, the 2 parts of the elevator need to be connected by the wood block with glue as 
shown below. The picture is for illustration only. Actually, the connection of the 2 
parts needs to be performed in the fuselage after the hinges are connected.
