Well I used the 30 and have no regrets! That is why they gave us a left stick
. I have really enjoyed mine and love the looks of it in the air! Mine came in at 14 and a half pounds and balanced perfect. The landings are a none event and other than the fact that it does not seem to like wind to much it has been a joy to fly. I am turning a 19x7 xoar at the moment but have a 20x6 waiting on the engine to finish breaking in.
And PS I have since added cockpit combing and a pilot to finish her off. I am also thinking of putting some combing around where I cut out for the engine.
