DJI Mini / Operating weight
Yes—some propeller guards put a DJI Mini above 250 g. The Mini 5 Pro guard discussed here specifically carries that warning. For any other combination, use the weight of the complete aircraft ready for flight, rather than its advertised base weight.
In Canada, less than 250 g and exactly 250 g are different categories. A battery, guard or filter can change the answer, so record the configuration you measured and reassess it whenever you change what the aircraft carries.

The Mini 5 Pro guard: check the exact instructions
SpeedyDrone’s DJI Mini 5 Pro Quick-Release 360° Propeller Guard product page says the aircraft will weigh more than 250 g after the guard is installed. It identifies the accessory as compatible with Mini 5 Pro and lists a firmware prerequisite; read the current product instructions and aircraft documentation before installation.
The listing specifies aircraft firmware v01.00.0400 or later, warns against use in windy environments and says propulsion, video transmission and obstacle sensing are affected. Read the exact guard instructions and current aircraft documentation; fitting a guard is a configuration change, not a general safety upgrade.
That statement applies to the listed product and model. It is not a measured operating weight for your aircraft, and it should not be used as proof that every Mini model, battery or third-party guard has the same configuration. Confirm compatibility and measure the actual flight setup.
A guard can be useful for a specific operating environment, but it is not permission to fly close to people or obstacles. Check the aircraft’s manual for limitations affecting sensing, flight performance, installation and conditions of use. A physical guard does not replace a suitable site or a cautious pilot.

Transport Canada states that the remote controller is not counted in aircraft weight, while equipment attached or carried, such as an optional camera or safety cage, is included. Its 2026 operating-weight explanation emphasizes the actual aircraft configuration during flight.
For a practical check, include the aircraft with the flight battery installed, propellers, any installed filter, guard, label or other item intended to remain attached. If you use two different battery or accessory combinations, weigh each one separately. Do not put the remote controller on the scale with the aircraft.
Use a scale suitable for small weight differences. Confirm it reads zero, follow its instructions, and repeat the measurement if the result is close to the threshold. Scale precision, rounding and changes to the setup matter. If you cannot confidently establish the operating weight, do not assume the aircraft remains below the threshold.
Scroll within the table to read every column.
| Configuration | What to record | Decision |
|---|---|---|
| Aircraft and intended battery, no added accessory | Measured weight and battery identity | Determine whether this actual setup is below 250 g |
| Same aircraft with guard or filter | Measured complete operating configuration | Reassess weight category and applicable rules |
| Different battery or other accessory | Separate measured configuration | Do not reuse a previous measurement without checking |
Measure each configuration separately; the table does not supply a weight for your aircraft.
Make a configuration record you can repeat
A useful entry identifies the equipment, the measurement and the resulting planning decision. Keep a photo of the assembled aircraft alongside the entry so a later accessory change is easy to spot.
Your aircraft weight record
- Aircraft and battery
- Record the exact aircraft and battery model.
- Avoid relying on a family name such as “Mini”.
- Installed equipment
- List the guard, filter and every other item carried in flight.
- Measure the complete setup together.
- Scale reading
- Record the reading, units and scale resolution.
- If rounding or uncertainty crosses the threshold, resolve it before treating the setup as a microdrone.
- Decision and changes
- Record below 250 g or at least 250 g, then identify the applicable operating requirements.
- Repeat after a battery or accessory change.
Do not subtract the advertised accessory weight from a different flight setup or treat a rounded display as a guaranteed margin. Record enough detail to repeat the measurement with the same equipment and scale.
What changes at exactly 250 g?
Transport Canada describes microdrones as under 250 g and small drones as at least 250 g. Its registration guidance states that aircraft weighing at least 250 g must be registered and marked, including an aircraft that reaches that weight because something is attached. Its pilot exam overview says pilots of drones with an operating weight of 250 g up to and including 150 kg must hold a pilot certificate.
The correct operation category and certificate depend on the proposed flight. A Basic certificate is not a blanket authorization for controlled airspace or flight near people. Advanced operations can require additional conditions, including an appropriate aircraft declaration and airspace authorization for the particular operation. Check the current Transport Canada categories and the exact aircraft configuration before planning the mission.
If an aircraft is registered for a heavier configuration, keep its registration and marking in order. Do not assume a particular registration workflow or safety assurance status for a modified aircraft without checking the current Transport Canada instructions.
Under 250 g does not mean unrestricted
Transport Canada says a microdrone pilot does not need to register that aircraft or obtain a drone pilot certificate solely for its microdrone operation. The pilot must still avoid reckless or negligent operation, comply with applicable restrictions and respect privacy and trespass laws. A microdrone is also subject to restrictions in restricted airspace; flying any drone at an advertised event requires an SFOC-RPAS. Review the microdrone rules for the current position.
Local rules and ground access also matter. Toronto park requirements apply separately from federal aviation rules. Read Toronto’s park by-law amendment for the park rule, and check the responsible authority for the proposed site.
Choose accessories by task, not weight alone
A practical Mini kit should answer how and where you intend to fly. Consider a compatible guard for the specific conditions described in the manufacturer’s instructions, spare batteries for the intended shooting schedule, and a suitable case for transport. Add a filter only when it supports the filming conditions and is compatible with your camera.
Before ordering, compare the aircraft model, accessory part and current instructions. SpeedyDrone’s Mini 5 Pro accessory collection is a starting point; product availability and compatibility should be checked on each listing.
If your configuration or mission requires a certificate, Drone Ground School and Drone Flight Training can help you prepare. Confirm course content and prerequisites. A training course is not itself a Transport Canada pilot certificate.
Frequently asked questions
Is exactly 250 g still a microdrone?
No. Transport Canada defines microdrones as weighing less than 250 g. Exactly 250 g falls at the start of the small-drone range.
Does a propeller guard always make a DJI Mini exceed 250 g?
Do not generalize across models and accessories. The Mini 5 Pro guard listing specifically says that installation puts that aircraft above 250 g. Check the product documentation and weigh your own complete configuration.
Does the remote controller count toward aircraft operating weight?
Transport Canada says the remote controller is not factored into the aircraft weight calculation. Anything attached to or carried by the aircraft is considered.
Can a guard make an otherwise restricted flight legal?
No. A guard does not replace the required pilot qualification, aircraft capability, authorization, property permission or safe operating plan.
Should I simply remove an accessory to stay under 250 g?
Choose the setup that is appropriate and permitted for the actual task. If the required setup is 250 g or more, plan for that configuration’s requirements rather than assuming a lighter advertised weight applies.
Choose accessories for your actual Mini
Start with the exact aircraft, battery and intended use. Match the accessory first, then check its effect on your operating configuration.
