We hope that if you go to the trouble to answer all of the questions in the DPZ Safety Rating Estimator you will have a better understanding of the qualities of a consumer RTF multi-rotor. Your submissions are welcome to improve the database.
- These multi-rotors are safe for all levels of pilots.
- They have a weight below 50g (1.76oz) and pose almost no risk to physical harm or property damage.
- They have thrust below 100g and are not capable of carrying any significant payloads.
- They have extremely limited control range and must be flown LOS (Line Of Sight) within 50m (165ft).
- If they have a camera it is low resolution and lacks any transmission capabilities and pose almost no risk to personal privacy.
- They have no intelligence features beyond novel control types and stabilization.
- Our Recommendation is they are placed in the same legal category as small paper airplanes, nerf guns, and baseballs.
- These multi-rotors are slightly more advanced and require an informed pilot, but they are still extremely safe and lack the capabilities to warrant serious concern.
- They weigh less than 250g (8.8oz) and do not pose a serious risk to physical harm, property damage or personal privacy.
- They have a very limited control range less than 100m (330ft).
- They may carry low resolution cameras, short range FPV, and small payloads.
- They may have limited intelligence, including novel control types and Tx based RTH (Return to Home)
- Our Recommendation is they are placed in the same legal category as large paper airplanes, frisbees, and footballs.
Class 3: Semi-Pro
- These multi-rotors require a responsible and informed pilot.
- They weigh enough to cause limited physical harm or property damage weighing up to 2.0Kg (4.4lbs).
- They are powerful enough to carry small payloads such as high resolution cameras, gimbals, GPS systems or up to 2.0Kg (4.4lbs) of carrying capacity.
- They have an extended control range up to 1.5Km (0.9miles) and can potentially fly beyond LOS (generally considered 500m for this sized aircraft).
- They can have many intelligence capabilities and do pose a reasonable personal privacy consideration.
- They are the consumer class that is the most likely to get into trouble and requires careful and considerate piloting.
Class 4: Pro Grade
- These multi-rotors are professional quality and have advanced capabilities.
- They pose significant physical harm and property damage in the event of a crash.
- They are capable of carrying large payloads above 2.0Kg (4.4lbs).
- They have advanced imaging and intelligence features, long range transmission for video and control, and may require two or more operators.
- These multi-rotors should only be flown by advanced pilots.
