Theory of a rotary take off?

I've commited lots of aviodomy in fixed wing - and was recently wondering about going for a rotary hour or two. Made me wonder about some of the differences. Take off sprang to mind - which foot gets all the effort?

Assume you are sat facing forward (always a good start) in a cheap piston trainer with manual throttle, advancing blade coming over your left shoulder. That would encourage the bird to yaw left when increasing power and pulling collective? So, a bit of right foot to get it back again? (or keep it there in the first place - with 'anticipation' being the key).

True/False? Any other bits to take into account when making that first transition from ground to air?

What about the rotary version of steep turns - I suppose "spot turns" would be more common in a vertibird? Does yawing towards the advancing blade cause any bigger (or lesser) drama than yawing towards the retreating blade? Rotor RPM and all that?

Does any of this make sense - or am I just gibbering?

I'd like to understand a bit more than the average muppet if I do go and blow Santas money ($350) on a rotary hour or two - and then, the follow up question - should I do two hours in a Bell47, Scweitzer or 30 minutes in a 206?
