# Introduction

n Standard UX5 toolkit n Orderable parts n Removing parts from service The Trimble UX5AerialImaging Solution Maintenance Guide provides instructions for customer maintenance oftheTrimble UX5 aerial imaging rover and launcher. Customer maintenance is required to keep the UX5 in good working order, and to replace parts that are designed to take the impact oflanding, in order to protect the more expensive parts ofthe UX5. Check the UX5 and launcher after each flight to ensure the equipment is in good working order, referring to the instructions in the Trimble UX5 AerialImaging Solution UserGuide. Perform any maintenance required using the procedures in this maintenance manual. Ifyou note any issues not covered in this guide, contact yourTrimble distributor. Note –Allprocedures describedin thismanual applyexclusively to the Trimble UX5 aerialimaging rover andlauncher.

### Steps WARNING – Before performing maintenance on any part of the UX5 aerial imaging rover, always make sure that the UX5 battery is disconnected from the aircraft:

1. To disconnect the push rod from the outboard elevon: a. Position the ball link pliers with the large U-shaped side between the elevon horn and the push rod.

Trimble UX5 Aerial Imaging Solution Maintenance Guide 102 UX5 maintenance

b. Close the pliers and align the extrusion on the inside ofthe pliers with the screw.

c. Apply force on the pliers until the plastic part ofthe push rod detaches from the metal ball.

Trimble UX5 Aerial Imaging Solution Maintenance Guide 112 UX5 maintenance

2. To remove the bottom servo housing: a. Turn the UX5 body upside-down. b. Unscrewthe two screws from the bottom servo housing using theTorxT8 screwdriver.

c. Remove the bottom servo housing.

3. To remove the servo assembly from the UX5 body: a. Gently push the servo from the underside ofthe wing and out on the topside ofthe wing. b. Disconnect the servo connector by pushing down on the locking clip and pulling the two

Trimble UX5 Aerial Imaging Solution Maintenance Guide 122 UX5 maintenance

pieces apart. c. Clearly mark the removed servo as a scrap item.

4. To connect and insert the newservo assembly: a. Turn overthe UX5 body so that it is right-side-up. b. Connect the newservo assembly to the electronics ofthe UX5 body. Make sure the locking clip is secured. Note – Make sure the connectorclip haslockedcorrectlyin place. The locking clip is essential forsafe operation asitprevents the connectorfrom coming apart duringflight.

Trimble UX5 Aerial Imaging Solution Maintenance Guide 132 UX5 maintenance

c. Install the servo assembly into the UX5 body from the upper side, making sure it sits flush with the wing surface. 5. To position the connector: a. Turn overthe UX5 body so that it is up-side-down. b. Position the connector so that the wires going into the foam sit tidily inside the opening of the grey plastic and the wires on the servo side are left free. CAUTION – Poorly inserted wires might cause damage to the wires. This can lead to mid-air failure, resulting in damage to the UX5.

6. To close the bottom servo housing: a. Insert the bottom servo housing in the UX5, making sure that the servo wires are not squeezed between the two housing parts. b. Hold the servo in place using the spring clamp. Make sure that the clamp is positioned in the middle ofthe servo housing (the middle ofa line between the two screws is a good reference) without obstructing the servo arm. c. Use the calibrated torque (0.55 Nm) TorxT8 screwdriverto attach the two screws without

Trimble UX5 Aerial Imaging Solution Maintenance Guide 142 UX5 maintenance

tightening them. Finish by tightening first the rear screw and then the front screw.

7. To attach the push rod to the outboard elevon: a. Position the ball link pliers with the large U-shaped side at the push rod and the small Ushaped side on the other side ofthe elevon horn. b. Close the pliers and align the large U-shaped side ofthe pliers overthe plastic part ofthe push rod.

Trimble UX5 Aerial Imaging Solution Maintenance Guide 152 UX5 maintenance

c. Apply force on the pliers until the plastic part ofthe push rod attaches to the metal ball.

8. Check the elevon trim. To do this, you must run the flight checklist in the Aerial Imaging software and perform the Check elevon trim step ofthe checklist with the newservos. Note – Ifrequired, use the Torx T6screwdriver to adjust the elevons. The outboardelevon shouldbe leveled with the inboardelevon (less than 1 mm ofoffset).

WARNING – Before performing maintenance on any part of the UX5 aerial imaging rover, always make sure that the UX5 battery is disconnected from the aircraft:

1. To remove the eBoxfrom the body ofthe UX5: a. Use theTorxT10 screwdriverto remove the screwofthe eBoxfrom the body.

b. To remove the eBox, pull the pitot tube holder (do not pull the pitot tube) so that the eBox pivots around its back. 2. To disconnect the three cable connectors running along the bottom ofthe eBox bay: a. Remove the cables from their cable duct. Note – Do not use sharp tools toperform this action. b. Forthe power cables, pull the connector parts apart. Forthe signal cable, push down the clip and then pull the connector parts apart.

3. To remove the drive unit from the body: a. Use theTorxT10 screwdriverto loosen the three screws that attach the motor housing to the body.

b. Gently push the two capacitors ofthe motor controller backward through the tail ofthe body until the drive unit loosens from the body.

Trimble UX5 Aerial Imaging Solution Maintenance Guide 202 UX5 maintenance

c. Remove the drive unit from the body and then mark the drive unit as a scrap part.

4. To attach the new drive unit to the body: a. Insert the three cables from the new motor controllerthrough the tail ofthe body into the eBox bay. b. Gently pull the red and black power cable further into the eBox bay until the motor housing slides overthe tail ofthe body. Do not pull on the signal cable.

c. Fasten the motor housing onto the body with the new, coated TorxT10 screws and washers using the 1.2 Nm torque screwdriver. Make sure that the plastic washer is on the side ofthe motor housing. You may need to push the drive unit slightly to align it with the screw holes.

Trimble UX5 Aerial Imaging Solution Maintenance Guide 212 UX5 maintenance

Note – Do not use the old Torx T10screws anddo not use the normal Torx T10screwdriver. The 1.2 Nm torque screwdrive makes a clickingsoundat the moment the screwis tightened to the correct torque setting. 5. To connect the connectors ofthe three cables running through the eBox bay: a. Connect the connectors. Forthe power cables, make sure to connect the black wire to the black connector and the red wire to the red connector. Forthe signal cable, make sure the clip is well secured. Ifthe cables are too long at the rear ofthe eBox bay, push the motor controller a few millimeters back toward the tail ofthe body. b. Insert the cables into their cable duct. The connector ofthe signal cable fits into the cavity nearthe wiring box. Once this is finished the cables in the eBox bay should look like this:

6. Check the following: The red power cable is connected to the red connector. c The black power cable is connected to the black connector. c The signal cable connector is well-secured. c All cables are inserted into their duct. c All three screws attaching the motor housing to the body have a metal and plastic washer and are tightened to the correct torque. c

7. Insert the eBox again and fasten it to the body using theTorxT10 screwdriver. 8. Go through the flight checklist and make sure the motor is emitting a sound after arming the UX5. Disarm the UX5 immediately afterthis check. WARNING – Do not leave the system armed. Once the system is armed, the motor can start, causing parts of the UX5 to move. This can cause personal injury and/or damage to objects from moving parts. 9. Scrap the old drive unit and make sure that it does not return to service.
