What is an inline flybar arm
When you say in line flybar arm are you taking about this? Just wondering, If this is what your talking about, I've never heard it called that before. I've always heard it called the birdcage or flybar stiffener.
If this is what your taking about, you don't need it. You won't see an differences in the way it flies, it's just something that can get damaged in a crash. It's more for looks then anything.
