I don't doubt that.

It was the particular formula behind the link. What made me think twice about it was I checked a couple of sport/pattern planes and the TVo came out low. For instance a Bridi Chaos .60 comes out to .7. That seems kinda low. I mean it's designed for aerobatics and should have a strong TVo right? I don't doubt the formula works. I wanted to know how it applies to sport r/c planes.
Thanks
