Meaningful answer

seeing this is an Interesting discussion. and everyone is refreshed on Centripetal and Centrifugal and torque forces . not to mention a Couple of Coupled moments.

Could some one help me on this one.

I am using my toy (DID I say toy ) Helicopter. RC.

here are the Specs.

Rotor Radius 27.5cm (oops. thats Rotor Radius, not diamiter my Boo )
Rotor RPM 2600
Weight at tip 5g

Given these. I am trying to get a meaningful answer.
I am Using CF = M x Vsquared over Radius.
I get a Tip speed of near 270kph
and when I get an answer using
5 x 269.547squared over 275
I get 1321.01
what dose that mean ?? IE what is the pulling power of the 5g weight on the Axis of rotation ?
is that 1.321kg or 131g or is my use of metric wrong or >>>??? ...
Please help me get a Meaningful answer
