With the addition of a hacker c-40 10t and model/sport c/f 395 blades I can do very fast loops and reasonable rolls.With the head speed@ 1900 I get only about 4.5 mins.air time.With the set up I'm using any wind up to aprox.10 mph is possible.When the wind is any more than that it is'nt any fun,so I get out my Nova.There is enough pitch range to climb out inverted also.
