[Flightgear-devel] YASim propeller fix

2003-10-18 Thread David Megginson
I've fixed the YASim code so that you can set the starting RPM from the property tree -- that means that it is now possible to start YASim propeller planes with the engine running, just like we do with JSBSim planes. This is a minor convenience on the ground, but it is very significant for in-air
