If you have more than 2 blades you need an adjustable phase head if you want to go 100% mechanical because 90 degrees won’t work.

The way they flew scale with no flybar before electronic controllers was to set it up with very low cyclic and collective pitch. They used –2.5 to 7 (some were as low as +5) collective pitch. I don’t remember the cyclic angles but I think it was only a couple of degrees. If you set it up like a modern 3D helicopter it will instantly go out of control.

That was with large scale helicopters with lots on inertia to help stabilize them. With a 450 it’s just doing to be that much harder to fly.

You will also need some very heavy blades to increase stability. Scale guys sue flat bottom or semi-symmetrical blades.

My advice is to get a SK540 and load the scale code that's designed for multi rotor helies – you will be a lot happier with the results.
