Hello,
thanks for the tip.
I don't know how much rpm my props are spinning.
next year I am gonna use telemetry so I am gonna experiment with it.
Many people coach me and they never said my plane is going to fast in the downline. But when you can get the speed as close as possible is always better. For time in downline etc. The plus point of the upline is that there is sound of the motor and props. This gives a weird effect because people think my plane is even to fast in the upline. So I am definitely gonna experiment with it. But as now iam happy.

Maybe you already know but my english is not very good. Sorry when you dont understand some things.
