Hi Bryan. When it's calm out I set the idle to as slow as it will reliably go. That way I can do a little slower, closer in style of flying. To me the larger props just seem to make the model steadier with fantastic acceleration if you need it. If there is wind, to accommodate a further out, larger style, I bring the idle trim up a few clicks as the braking can be too much. I don't play much with changing props for conditions as I think having a very consistent set up is better then making changes at a contest. But if you really need speed put a 22x22 on the front along with the rear and it really goes.

Glad to see you are liking the Contra. I was sold on it over three years ago with the first flight. There has certainly been a lot of development and lessons learned in that time. I currently have 2,400 flights on the Contra in 4 different models. I wish I had paid more attention to getting the model right when I first started using it. But now with what I have learned it's an easy switch in any model.
