Mmmm... it does seem like an awful lot more money for not a lot more. I'm sure it flies very smooth, as most brand new helicopters do.
I think the fact that it sounds like a 'proper' helicopter, and not a tractor is the appeal to most people.
It's a shame the Frank is still clinging onto the (universally hated?) t-bar cyclic system. Surely a proper cyclic wouldn't put that much more weight on?
Does anyone know if the R66 is "belt driven" like the R44?
