I just purchased the 60 sized Cap 232, and it looks great! And I'm a skeptic when it comes to ARF's. Is this plane really 3 D "capable"? On the box it states 60-90 2 stroke, or 91 4 stroke, yet on the companies website, it states 91-120 4 stroke. Which engine would you guys recommend? Personally, I like the sound and torque of a 4 stroke. Thanks for your help.
