The DJI Mini 2 boasts a top flight speed of 36 mph (57.6 kph) with a maximum flight duration of 31 minutes. It can fly as far as 10km away in perfect conditions. What is the DJI Mini 2 return to home height? Initiating an RTH (Return to Home) command on a drone will prompt it...
When driving a car it is important to know how fast that car is going. The speedometer gives a instantaneous speed reading of the vehicle at any given time. Knowing the units the speedometer is displaying is very important. Driving in an area with a posted speed in kph and reading the ...
Considering the speed at which a skydiver is typically free falling -- about 120 mph (193 kph) -- and the lack of options if something goes wrong, a parachute rig needs to be incredibly reliable. There's a lot of popular interest in the fine art of parachute packing. It has all the...
Taking a suborbital approach, California-based aerospace firm XCOR is working on Lynx, a two-seat commercial aircraft designed for high-altitude, supersonic flight. If successful, Lynx will cruise at more than 2,500 mph (4,000 kph) to an altitude of 62 miles (100 kilometers), then descend...
The five-to-10-speed transmission on most cars allows them to go 110 mph (177 kph) or faster with an engine-speed range of 500 to 6,000 or higher rpm. Diesel engines have a much slower operating speed than gasoline, and that goes double for the massive ones used in locomotives. The...
