The maximum speed is 400 km / h (PLEASE DO NOT FLY FASTER, OTHERWISE TERRIBLE THINGS WILL HAPPEN), if you accidentally did this, go to slow motion as fast as possible and wait until the speed drops below 400 kmh.
You can use two ways to fly - trottle (turns on the engine) or flapping your wings(VTOL up, down, up, down, up, down, and so on until your finger gets tired).
You can change the angle of the wing by using trim up. To caw caw, use the brakes.
To take off, use the trottle, then you can turn off the trottle and use the wings.

The common raven (Corvus corax), also known as the western raven or northern raven when discussing the raven at the subspecies level, is a large all-black passerine bird. Found across the Northern Hemisphere, it is the most widely distributed of all corvids.
It is one of the two largest corvids, alongside the thick-billed raven, and is possibly the heaviest passerine bird; at maturity, the common raven averages 63 centimetres (25 inches) in length and 1.2 kilograms (2.6 pounds) in mass. Although their typical lifespan is considerably shorter, common ravens can live more than 23 years in the wild.
The brain of the common raven is among the largest of any bird species. Specifically, their hyperpallium is large for a bird. They display ability in problem-solving, as well as other cognitive processes such as imitation and insight.
Linguist Derek Bickerton, building on the work of biologist Bernd Heinrich, has argued that ravens are one of only four known animals (the others being bees, ants, and humans) who have demonstrated displacement, the capacity to communicate about objects or events that are distant in space or time.
