Erik Does that will modify the original Jon's recommendation to start an engine ? Get the external Air compressor resources The engine will spin up to a maximum of about %25 N2 (%5.2 N1) This simulates the action of a pneumatic starter.- After reaching %15 N2, Cutoff to False Thanks -- Gérard http://pagesperso-orange.fr/GRTux/ J'ai décidé d'être heureux parce que c'est bon pour la santé.

And only if defined, otherwise it will not affect precious behavior.
