Safe troubleshooting

- Remove the propellers before inspecting a damaged arm, motor or airframe.
- Do not power or charge a wet, swollen, crushed or unusually hot battery.
Consumer aircraft diagnosis
Independent diagnosis for DJI Phantom 4 Pro, with clear advice on repairability, parts and whether repair is economically sensible.

Reported symptoms
Legacy parts, batteries and software support can be limited. We confirm a viable and economical route before chargeable work begins.
Try the safe steps first
These steps are deliberately limited to safe owner-level checks. Stop if the aircraft has impact damage, water ingress, a hot battery or anything that could affect safe flight.
Clear service choices
Choose a focused LDR bench check or a recorded service with certificate. Any repair, parts or delivery cost is explained and approved first.
A practical health check for a drone that needs a second opinion, a pre-season check or a clearer repair decision.
This is a focused bench check, not a strip-down, repair, official manufacturer report or certificate of airworthiness.
A fuller recorded inspection for owners, operators, used-aircraft purchases and fleet service files.
The certificate records the checks completed and findings at the time. It is not an official DJI report or a regulatory certificate of airworthiness.
£49 and £99 are base prices per aircraft. Parts, repair labour, delivery and manufacturer charges are separate. No additional work starts without your approval.
Prepare for service
We will confirm whether the controller, batteries, charger or payload should travel with the aircraft. Remove storage media and any data not required for the job.
Return delivery
We confirm the final carrier route before payment. Do not post a damaged, swollen, recalled or overheating battery.
Return delivery
Eligible UK parcels are returned using Royal Mail Special Delivery Guaranteed by 1pm. Select the final packed weight and the compensation cover required. We confirm eligibility and the final charge before payment.
Include the aircraft, batteries, controller, case and packaging.
Choose a level that reflects the aircraft's current market value.

DJI Phantom 4 Pro service questions
The physical LDR Basic Bench Check is £49 per aircraft. The LDR Service & Certificate is £99 per aircraft. Initial repair-enquiry triage is free; parts, repairs, delivery and manufacturer charges are separate and require approval.
Our current support position is legacy support. We confirm tooling, parts and the viable route before chargeable work starts, and we do not claim manufacturer-authorised status.
Record the exact warning, remove propellers before a visual inspection and do not power or charge a damaged, wet, swollen or unusually hot battery. The checks below are deliberately non-invasive.
Eligible UK parcels can use Royal Mail Special Delivery Guaranteed by 1pm. Packed weight, compensation, battery condition, value, size and postcode restrictions determine the final route.
