Hi Fred, for me the Quark was sublime, it has all the pedigree of being one plane to have in the hanger !
The Quark has also a very smooth flying pattern , which would make it very good for a beginners plane , but you must reduce the control surface rates lol
For in your face aerobatics I think 35mph winds would make the Quark come alive !
In 10mph winds she is smooth and accurate and for me a very good travel of lift in the light winds.
Sorry for breaking the elevator rods, I forgot how to fly on mode 2 lol
