Weight is only one factor in all speeds to be determined.
Leaving props and engines out of it, configuration and construction matter.
There is little design difference between the Airdrome Morane and the Airdrome Nieuport 11 - except one is a high wing monoplane and the other a biplane with a bunch of wires hanging out all over it.
With the same engine/prop combo the VH is going to be higher in the Morane, as the sustained continous power that is healthy for the engine isn't fighting all the drag of the biplane.
But let's not throw props out; the pitch of a prop (climbing versus cruise) really do matter. If one gets the prop carved for climbing it's at the sacrifice of cruise speed....
VH is one of those things that come out for real in Phase I testing....
