Question about scaling down real world aircraft

I'm trying to make an RC model of the V22 Osprey aircraft. Now the real world Osprey has a max vertical MTOW of 8000 lbs, give or take.

If I am going to build a one twentieth (1/20th) scale place, is it safe or silly to assume that each of the two rotor hubs or heads will carry:

8000 / 20 (for scale) / 2 (per hub) = 200 lb of weight?

Or am I scaling it down completely wrong?
