Instructions
Thank you for purchasing the E-ite® 10- to 15-Size
Electric Retracts. These self-contained units are
powered from your model’s receiver and do not require
separate servos.
The retracts are supplied with coil struts installed, plus
adjustable axles, wheel collars, Allen wrenches and a
3-into-1 wire harness (for the tricycle set) or 2-into-1
wire harness (for main gear set). The nose gear unit is
steerable and has a slot in the sliding steering arm to
prevent binding of the steering cable when retracted.

Installation
1. Test t the retract unit in the wing or fuselage to
determine the strut length and axle location. Cut the
strut to length using a cutoff wheel in a rotary tool.
2. Make two at spots on the end of the strut with a le
and use a 2.5mm hex wrench to secure the axle to the
strut. Apply threadlock to the threads of the retaining
screws so they do not loosen from vibration.
3. Install the wheels on the axles. Slide the brass wheel
collar onto the axle and secure it using a 1.5mm hex
wrench. Apply threadlock to the setscrew to prevent it
loosening due to vibration.
5. Install the retracts in the model using the screws
provided with the kit or those of your own choice. A #4 x
1/2-inch wood screw works well. You will nd the main units
require the use of a 100 degree countersunk woodscrew
while the nose unit requires a button head woodscrew.
Radio Connections and Operation
1. Plug the connector from each of the retract units into
the 3-into-1 wire harness supplied with the retracts.
4. Mark the retract mounting hole locations on the rails
using a pencil and drill appropriately sized holes for the
hardware you intend to use.
Nosegear Steering
Connect the steering pushrod to the steering arm on the
nosegear.
2. Plug the single lead from the wire harness into the
gear channel of your receiver. An auxiliary channel can
be used if the gear channel is occupied.
3. Before operating the retracts in the model for the rst
time check that there are no obstructions in the wheel
wells that could impede operation of the gear.
4. Turn on your transmitter and receiver. Use the gear
or other assigned switch to activate the landing gear
and check that it operates correctly.
5. If the switch direction is opposite of that desired, use
the reversing function in the transmitter to change the
retraction direction.
6. If using a 2.4GHz radio, once you have set the
correct servo direction be sure to rebind the system
before ight.
