Thread: Velocity Loss From Summer to Winter.

Sounds about right too me. I dont loose as much but do loose some. It works with helicopters as far as density goes well. Higher the air density the better the engine and blades perform. They bite better air causing resistence of sorts. Same with anything flying thru air.
I would look at another powder if your worried about it, but 2810 is still good enough for a 6.5 to 700 odd.
