In defense and clarification. "aiming" is when the plane flies where ever you point the prop, ie; flying on the Prop. Yep, you can fly some electrics on the prop too, but I'm still flying the slower park flyers, and they fly "on the wing", ie; if there is not enough airspeed they stall, and no prop on a slow flyer will pull you out. It is either drop the nose, or hit the ground.
Full Agreement on the turbulance of trees, and the effect on electrics, or slow flyers. You can launch or ROG into the wind, and find that that same wind is rolling over trees, and blowing you right back onto the runway.
Another "wind" thing I find is that I launch in the school yard where there is no breeze, then get my Tubby Cubby up about 50 feet or more, and wow[img]i/expressions/face-icon-small-shocked.gif[/img] is there a stiff 10 MPH or so breeze "up there."
