CARB ICING
The onset of carb icing is likley to be masked initially by the governor compensating for power loss by automatically opening the throttle.
The flywheel effect achieved with a propeller bolted to the engine will give you plenty of warning of ice-induced power loss. The prop will also continue to turn the engine for you while you finally decide what has happened, pull the carb heat out, leave it out and hope that the think will pick up again.In the heli we dont have this comfort, it will likely quit without warning.
I enjoyed the R22 and found myself using more heat than necessary. However, I would rather suffer a slight power loss and excessive fuel consumption than risk engine failure through carb icing.
I have found the contributions here very useful indeed thank you and feel more confident as a result.
I hope to be flying my new Raven 2 within the next couple of weeks and plan to be very, very careful with it.
