As I've mentioned, Ive been flying this setup for a little over a year now. It would be perfect for scale jobs.
One thing you could do too, is weight the flybar heavy, and it would fly really scale too.

On a side note....
hobbyparts.com has fiberglass/plastic scale fuselages for the 450's. Hughes 500's, Bell 222, and even some nice agusta bodies. I've been thinking about building a scale heli myself...probably a hughes 500MD in solid black. You could pretty much build a scale heli for a little over 200 bucks...49 for the fuselage, and 156 bucks for the guts.
