Going upwind n turning will slow you down versus going downwind, which will speed you up. I don't see anything wrong with slowing down a bit, or speeding up, it helps with your situational awareness. You can continue to make continual adjustments to maintain speed, however, as long as the chopper remains in trim you're doing ok controlling the chopper. I mean, it's not as if you're gonna get a speeding ticket or a ticket for impeding traffic. Main thing is to fly the chopper, IMO
