Re: A little light - in fact it's not
That's not on the low side for drones these days, even many professional drone users are dumping larger rigs, going to the Inspire, Phantom and Mavic.
The Mavic is the go-to drone for consumers (sub 1kg) and so is the cheaper Spark (even lighter still). The latest ArduPilot drone, the Skyviper is under 250 grams.
Remember, the purpose of the testing is to assess the risk from consumers as licensed operators would be operating within the law.
