> how much G do you think you can actually pull in a helicopter?
I've often wondered that. One thing that struck me about the R44 (maybe others too) is that it has no published G limit (not in the PoH anyway). Is this because you will run out of lift long before you break anything? Or what? Some helicopters CAN be looped - leaving aside the question of whether it's a good idea or not (yes, I do know it isn't) - meaning they can pull at least 3G. I asked my instructor at the time why there were no limits and he didn't really know. Yet every fixed wing aircraft, even if all it has is a 65HP engine, has published G limits.
