Many of us may be used to helicopters in other sims and may be just applying full throttle and letting the governor ‘take over’ and control the engine.
The Aerofly r22 is more realistic than that. If you have a physical throttle axis bound you can slowly apply power until the needles are in the green and you will still have physical travel left to adjust rpm in flight. This models how the r22 correlator works in real life (just without the physical feedback).
If you have been applying full throttle at startup you will notice your manifold pressure is higher than expected and your rpms are high and not in the green arc.
This is nice attention to detail IPACS. Well done
