Evening all,
I've been toying with putting together a schedule of preventative maintenance measures to hopefully head-off any physical/mechanical issues at the pass and keep our tallies of landings equalling the take-offs. Comments, criticisms, additions and subtractions welcome.
BEFORE & AFTER EVERY FLIGHT
* Check condition of props (run finger along leading and trailing edges, flex both blades to check for hairline cracks);
* Check motor shafts have no free play (missing E clip? Loose bell housing screw? Bad bearings?);
* Check motors move freely when spun by hand;
* Check condition of battery spade connectors and data pins (level, free movement, clean);
* Check camera mounts are secure (and any other attachments, e.g. Flytrex core);
* When powered up and idling confirm no unusual noise or vibration from motors.
EVERY WEEK or EVERY 10 FLIGHTS, WHICHEVER SOONER
* Visual inspection of shell and other plastic components for cracking/damage (landing skids, camera mounting plates, etc.);
* Check tightness of motor retaining screws and shell retaining screws (both 2.0mm hex);
* Clean data spring pins and battery contact pads with alcohol and swab or proprietary electrical contact cleaner and cycle spring pins several times to check for spring weakness and full unimpeded travel;
* Plug in to Vision Assistant and check tx & IMU calibration state and all battery cells have good balance (repeat for all batteries);
* Check batteries for number of cycles and discharge per DJI recommendations if required.
EVERY MONTH or EVERY 40 FLIGHTS, WHICHEVER SOONER
* Remove upper shell and check state of all wiring - plugs fully seated, condition of all solder joints, condition of visible circuit boards and wiring runs, internals generally clean and no debris/loose items.
* Remove motors and check security of E clips, condition of bearings and general visual inspection.
* Remove rubber cover from Vision camera servol mounting point and check tightness of the small cross-head screw.
All thoughts welcome...
