turn onthe autopilots stabilizer channels (srry can't remember the English name) and practice by hovering close to ground, and try taxiing around the base, because it has wheels you can do this.
Also, remember that it is harder to fly with many heavy bombs and missile, the normal loadout of 40x С-8Ком (S-8KOM) and Вихрь/Vikhr and is fine. What mjeh said is about the rest of it.
There are some good videos explaining the physics of the rotor blades, and how to not kill the blades... just don't go over the speed limit of the helicopter with your set loadout, and don't pull to many G forces and you will be fine.
More than anything the Ka-50 takes practice, but it is definitely worth it as is a very good attack chopper and extremely fun :thumbup:
