The throttle equivalent of helicopters (collective) is typically
controlled by a lever on the left side. Unlike aircrafts, this
lever has to be pulled to increase 'collective' input. I'm not
sure if I did it the right way, but here is a working patch to
add a "throttle-reverse" property that should be set for all
helicopters.
