Hi Guy's!
To say the least where I fly in a open park with buildings a way's away and light towers for baseball I get turbulance when the wind blows. Now think of being in a room with no furnature, or people. The rotor wash will be dreadfull. Now add furnature and people and the risk has jumped 1000%.
I was breaking in an OS 50 yesterday in the front yard.... there was a little breeze but the cloud of exhaust hung over the yard 3 doors down.

The yard is caked with a slime of oil which is still there today. Just think what their living room was like!
I have had my near fatal episode so I know what it feels like.

P.S. it's 2 years since I started flying helicopters and there is nothing out there that brings more enjoyment in the hobby.
