With Propellers OFF and Battery Removed
Camera
o
If needed, replace gimbal dampeners (4) and dampener retainers/locks (2) if present. (silicone fill dampener NO leaks)
o
Inspect mounting rails on camera and aircraft for loose, damaged or worn rails.
o
Apply a small amount of graphite lubricant to a tissue and brush lengthwise on the gimbal rails if needed.
o
Slowly by hand rotate & check gimbal arms for smooth rotation and no damage.
o
Inspect contacts on the camera and pop-up contacts on the aircraft for wear and clean as necessary. Electronic cleaning solution
applied to a paper towel or lint free cleaning cloth is recommended. Use Care to not damage the pop-up contacts on the aircraft.
o
Remove the protective lens and inspect camera lens for any damage (scratches), clean with a microfiber cloth, inspect and clean
camera threads with a brush. Use care to not damage lens. Clean & re-install protective lens
o
Clean the outside of the camera.
Aircraft
o
Inspect Body for Damage (cracks, loose or missing areas).
o
Clean the louvered air vents of dust/debris. DO NOT blow dirt into aircraft body (electrical circuitry inside and the newer vents have
a fine filter bonded to the body and you will loosen or tear it).
o
Check motors by lifting each motor and adding some side pressure (to check for looseness). If any motor is showing signs of play,
tighten or replace.
o
Inspect each motor's wiring protective sleeve leading into the airframe for wear.
o
Clean each motor & arm of dust & debris. Give a slight twist to each arm & motor mount - verify rivets are tight. Slowly turn each
motor by hand to ensure no grit is inside and moves freely. If needed use canned air and a small brush to remove any debris.
o
Inspect each propeller for any cracking, stress marks, pitting, worn lugs on bottom etc.
o
With a propeller check each Quick Disconnect 3 (A) and 3 (B) for proper operation and propeller is Not loose in mount. Replace if
bad or questionable performance.
o
Check arm locking mechanism for positive operation. When the arm is raised it should "Click" in place and not be loose.
Replace locking mechanism as necessary.
o
Clean Front Sonar Ports, removing dust & debris and Bottom Ports if Realsense installed.
o
If RealSense is installed clean the front lenses and camera (pin hole) lens front and bottom of module.
o
Remove antennas from their sleeves and check for any wear or frayed wires.
remove and save for reuse.
o
Remove the landing gear servo motors and check contacts for wear, clean. Give a slight twist to each shaft and verify rivets are tight.
On aircraft check pop-up contacts for damage and clean with electronic contact cleaner applied to a paper towel or lint free cleaning
cloth is recommended. Use Care to not damage the pop-up contacts. Verify screw holding leg to servo (Landing Gear Seat) is tight.
If necessary apply a very small amount of graphite lubricate on the sides of the servo motor when re-installing.
o
Check landing gear foam feet for wear and replace if necessary.
o
Verify all screws are secure. Hand tighten if necessary. DO NOT overtighten as this can damage or weaken the plastic,
use a small amount of lock tight if needed.
o
Start aircraft and verify normal start up sequence and camera is level and facing forward.
o
If RealSense is installed listen to the cooling fan for unusual noise & observe for smooth operation.
