Trying to get a N1 gauge to work correctly in a helicopter. Yes it works, but on start up it leaps up to 50+% and when the fuel is shut off, instead of spooling down, it instantly drops to zero.I have tried using Helo-Turbine, jet and turboprop engines, but the effect is always the same. I suspect its something hardcoded into the flight model, and have scanned the air file and compared to other air files that I know have a functional N1 (B747, for instance) but cannot for the life of me see what could me preventing the N1 from working correctly.Any Ideas??Steve

Never mindFigured it outSteve:-))
