Heres my next question (I know, I'm full of them).

How doess knife edge, effect top speed? In other words, are you better off holding close to knife edge around the course, or are you better off (speed wise) banking to a 45 degree angle in the straights.

My opinion is that straight and level flight is definately the fastest, however does all the aileron movement of 90 degrees for the turns and 45 degrees (to level) for the straights bleed off more speed than what you would have lost if you stayed in knife edge??

I'm not sure here. I probably stay banked more than I should, but not sure if the extra aileron movement is worth the gain (or loss) in speed.
