You need a sportsfinder. If you can't buy one a suitable wire frame guide
would be easy to make.
The KO Rapid I have was designed as a press camera for fast action photos
without having to worry about focus. It works great that way. With
rangefinders users were expected to know and use depth of field. Often we
just set the distance and the viewfinder was only used for framing.  A guess
of the distance was usually sufficent. With a 90mm, f3.5 lens everything is
in focus from 50'. Stop it down and everything from 10' or less could be in
focus. There used to be tables for the depth of field and books showed how
to calculate it.

How low do you fly ?
