Actually, they work just fine for me. I mount them on a standard clear plastic flight stand and place that over the actual aircraft card (with which I execute the actual movement). For altitude, I merely use a number counter to indicate level placed on the card. K.I.S.S. Principle.
The models themselves are rugged once built, especially those that require brass wire for the struts.
If you like white metal aircraft and want some of the more exotic types of aircraft used in the Great War, I highly recommend Reviresco's wares.
John McEwan is a class act who has been a part of our industry about as long as I've been alive, and he's really something of an unsung hero of this hobby of ours, having introduced and/or promoted everything from 3D aerial combat using plastic model aircraft, 3D starship combat games using miniatures, sci-fi ground combat with miniatures, and quite a number of historical subjects for wargaming essentially ignored or neglected by other manufacturers.
I highly recommend his models and service, his WW1 aircraft kits being no exception.
