I have a couple questions about an extra 300XL. I am thinking of buying one that has been modified with giant control surfaces and a lightweight design for 3d flying. Do extras in general snap roll when you pull up hard like a cap? does it nose tuck when full rudder is applied? those are the two symptoms i collide with and am very dissappointed with in my cap. Are there any other bad habbits the extra inherently has?
