RE: Tower Hobbies Razor 3D GP/EP ARF 52
I still haven't flown mine so I can't say - but I usually put 30% exponential in as a start and use triple rates all on one switch. I know some pilots who use none on their 3-D rates as they say they need the fast response and others who use 60% on their 3-D rates to make the response more managable near neutral point. So I guess it's a personal thing.
