not all of the mfr engines use premix, the 787b has a metering pump
how'd you find this out?? also was it to do with rules at le-mans that they couldn't premix?

wow, ok thats news to me, i always thought it just ran straight premix with no MOP..

which moves as fast as the engine can rev!
It would never be able to keep up free reving in neutral.. still very impressive none the less..
I'm still friggen trying to design a circuit to work like this.. My thoughts so far are using the cas output to drive a PWM circuit.. easy.. BUT, how the hell do you tell it to 'move back' instead of extend? I'm now considering two motors, one to extend and one to draw it back, just need two differently design PWM circuits..
hehe might go ask some of the electrical engineer lecturers some more.. they'll know..
I think its a great idea, and the mechanics of it are quite simple, just the electronics will be a **** fight.
