Hello, I've been receiving some warnings in my default helicopters on FSX (I have no addon helicopters), and as soon as I start the flight, a warning starts flashing on the panel about "ROTOR LOW RPM". This generally means that I can't get off the ground whatsoever. Any help would be greatly appreciated.

if its the Robinson you may have to wait for the rotor to match engine speed - when they settle down the low rpm light will go out - can take a few moments. If you start with auto engine start keys then just wait until low rpm light goes out.The jet ranger I have forgot - use the Dodosim ranger - more real.All the bestdmb

Thanks for your help! I'm considering the Dodosim Jetranger- looks amazing!

I don't know whether you're aware, but the throttle lever on your controller usually is hooked up as the 'propeller axis' i.e it becomes the collective pitch control, with a second slider devoted to the throttle. This second slider is used to bring the rpm up to the correct rpm (usually a green arc), with lift being provided by gently increasing the collective pitch.Yes - the Dodo Ranger is still the very best helicopter on the market. The authenticity is head and shoulders above all others.

If you get the Low RPM warning on any FSX Helicopter, just hold down CTRL+F4 and it will sent max RPM and clear the warning.
