Head Speed for 450 5 Blade Head

[sockrim]

Hi All,
I have the option right now to build an Aerodyne MD500 running mini titan mechanics. I am in the process of purchasing the drive system and was wondering what head speed I should be looking at?
I will be running a CC ICE50 governed, and I am looking at the Scorpion 1630kv as I want to run 6s.
It is a 5 blade CopterX head, and the blades are the Copterx scale plastic/glass reinforced 320mm blades.
Tail I am not sure about yet, I will work on this once the head speed has been decided.
It will also be electronically phased and stabilised by a BeastX-Version 2 at this point.
What are your thoughts on head speed range?

i ran mine at 1900 and it ran great. but....your going to need to speed up the tail quite a bit. do a search for it. theres plenty out there. you could go with 4 blades and not have to worry too much about tail authority. but that 5th blade just messes everything up. good luck.
