I too buildt it with quad flaps although I was advised to use the full span ail first until I
get comfortable with my new 2nd plane.
Quad flaps can always installed later.
Didn't listen and on the fifth flight i played with the mixes. The plane handled different
and much faster responding in rolls, loops and turns with flaps to elevator mix and
ail/flap to elevator mix.
Forgot to turn the mixes off before turning into base leg and overcontroled the plane,
it turned too fast and i lost orientation.
I guess I better fly without any mixes for a while until i get more comfy with the stick('s).
Exponential is also quite useful.
Good Luck.
