At first reduce the collective to minimum. To increase the rotor thrust, you have to “pull” the collective. Therefore for minimum collective you have to push the control down (that is the full acceleration position (!) of the thrust controller). Thus: Thrust controller to “full power” what means minimum collective. The engine is started with “}”. After few seconds the rotor starts to turn and accelerates slowly. Hold the stick and the pedals approximately in centered position. Wait until the rotor finish its accelerated (there is an instruments for engine and rotor speed, in the Bo105 on the left in the upper row). Then pull the collective slowly (really slowly!!!). Observe exactly the horizon. If the heli tilts or turns only a little bit, stop increasing the collective and correct the position/movement with stick and pedals. If you are successful, continue pulling the collective (slowly!). If the helicopter flies, increase the collective a little bit more and try to keep the helicopter in a leveled position. The main difficulty is it to react to an inadvertent rotating motion of the helis with the correct measure. Only three things can help you: practice, practice and practice. It is not unusual that the time one needs to get a halfway good looking hovering flight is to be measured not in minutes, but in hours. Note: The stick position in stable hover is not the center position of the joystick.
First reduce the collective to minimum. To increase the rotor thrust, you have to “pull” the collective. Therefore for minimum collective you have to push the control down (that is the full acceleration position (!) of the thrust controller). Equally, “full power” has the thrust controller at idle. Started the engine with “}”. After few seconds the rotor will start to turn and accelerates slowly. Keep the stick and the pedals approximately centered. Wait until the rotor has finished accelerating. For the Bo105 there is an instruments for engine and rotor speed on the left of the upper row.
 
Once rotor acceleration is complete, pull the collective very slowly. Keep your eye on the horizon. If the heli tilts or turns even slightly, stop increasing the collective and correct the position/movement with stick and pedals. If you are successful, continue pulling the collective (slowly!).
 
As the helicopter takes off, increase the collective a little bit more and try to keep the helicopter in a leveled position. The main challenge is reacting to the inadvertent rotating motion of the helicopter with the correct control inputs. Only three things can help you: practice, practice and practice. It is quite common for it to take hours of practice to achieve a halfway good looking hovering flight. Note: The stick position in a stable hover is not the center position of the joystick.
