Narrative:

I took off from a parking spot near the hangar between 2 rows of aircraft. While taking off I noticed that the rotor downwash was moving the nearby parked aircraft. I turned away but the parked aircraft, got some more of the downwash. To avoid this problem I should tow the helicopter away from parked aircraft before flying.
