The answer to this one is no. Yes a plane does have to be traveling at a certain speed in order to lift into the air. But as long as the aircraft maintains that speed it can either climb or descend. The speed merely determines how fast it climbs.
the flaps on a plane increase drag and they create lift so the piolt can fly the plane at a lower speed.
Because it's speed generates lift on the wings.
The first plane was the experimental Ball X-1.
ultra sonic !!
The X-15
Yes there is a specific fuel needed to fly a RC Plane. This fuel is: Rapicon Max Power RC Airplane Fuel 15% You can buy it here: www.amainhobbies.com
A complete change in the "laws" of physics!
Because of the speed that the plane flies.
About 600 mph.
Normal jet airliners fly at around 550 mph.
The time of flight to fly from Italy to Dominican is about 15 hour if the plane is flying at 400km/h. It all depends on the speed of the plane.
