Overweight penalty?

[EyesWideShut]

Think I might possibly know all of that?

The OP was talking about a situation where they add prop guards, decal, landing legs or some other attachment that takes the drone to 250g.

@ajkm, in your signature, I see you have some Transport Canada drone accreditation as an Transport Canada Advanced Ops RPAS Pilot & Flight Reviewer, and an ISED Canada ROC-A Examiner . Congratulations!

I would be surprised if you didn't know the Transport Canada RPAS regulations and the benefits of owning a mavic mini in Canada as @Kbviper stated. Basically as he said, the only regulation is fly safely and don't be stupid.
