.........You also want to watch the speed on the A-4. I don't think you want to take her too fast,
+1, it's real easy to push this airframe past the limit, p-70 + left stick in the ON position too long = folded wing

(all my fault, not the airframe)
this airframe is also VERY sensitive to CG changes, a 1/4" can make all the difference in the world of a great flier and a brick.
