The Skyrover S1 sold for $236 on Amazon at the end of August, against $759 for the cheapest DJI Mini 4 Pro kit on DJI’s US store. Both prices come with a catch. The FCC has proposed stopping new S1 sales, and DJI’s US store lists every Mini 4 Pro kit as out of stock.
FlightBrief has not flown either drone. The specifications below are each maker’s own.
The S1’s FCC problem
On 17 July the FCC proposed banning further imports and marketing of equipment from nine companies. The list includes the S1’s aircraft and controller, filed under the company WaveGo Tech. Owners could keep flying them.
If the FCC adopts the proposal, sales stop 30 days after it is published in the Federal Register. Comments closed at the end of August, and the FCC has not ruled.
The FCC also proposed a $25,000 fine on WaveGo in July for not answering an FCC inquiry. The S1’s FCC filing says it is made in Malaysia. Security researchers have linked Skyrover’s hardware and app to DJI’s systems, DroneXL reported; neither company confirms a tie.
The Mini 4 Pro’s stock
The Mini 4 Pro was authorised before the FCC added foreign-made drones to its Covered List in December 2025, so it can still be sold and flown. DJI’s US store lists it at $759 with the basic controller, $959 with the screen controller and $1,099 as a Fly More Combo. All three showed as out of stock on 14 October.
Since 3 September, imported consumer drones under 25 kg without thermal cameras have also carried a 25% US tariff.
The specifications
The Mini 4 Pro has the larger sensor, 1/1.3-inch against the S1’s 1/2-inch, and shoots 4K at up to 100 frames a second against 60. DJI lists 20 km of range on its O4 video link and obstacle sensing in every direction. Skyrover lists 12 km and sensing forward and down only.
The S1 claims the longer flight, 40 minutes against 34 for the Mini 4 Pro’s standard battery. Both take 48 MP stills and weigh under 250 grams. DJI states hover accuracy of +/-0.1 m with its vision sensors; Skyrover publishes no figure.
