The correct terminology is "Pirouetting Flip"..There has been a variation of it called the "Chaos". Maybe there is one called Pyro (and does exist) but to date I have only heard pyro referred in the Heli World by Kontronik, they called their motors that.
Piro-Flips involves stirring the cyclics. You are correct when it comes to synching the rudder with the input of the cyclic. At first you are correcting with the cyclic while feeding in rudder and collective. If you record on your SIM session while doing piro-flips and watch your stick movements, they look like inputs rather than stirring. Over time, it will transform into a stir. You are mixing the controls to flip, rotate and level simultaneously.
As most maneuver are being learnt, you have to consider the away maneuver. So I would suggest this:
- Pick left or right rudder
- Initiate from upright tail in
- Initiate when nose in inverted
- key off tail when upright and the nose when inverted
- with the above orientation, you can stir @ 12 o'clock
- this will push heli away
I will warn you, this is different than a full stir pirouetting flip. The above is half and than half. So you will not achieve an upright to inverted back to upright piro-flip with one complete stir but you will be able to do a pirouetting flip. To tell you the truth, not all everyone piro-flip the same, stir the same or look the same That is something you can refine later on as you get the hang of it.
But I would suggest learning Traveling Pirouettes so you can level and control the heli before stirring the cycles. Being comfortable with pirouetting circles is important and you have to learn to correct at multiple points. This puts the Heli in the most awkward orientation (same as in pirouetting flips). This way, you can fly through the piro-flip maneuver. If you could consider the piro-flip is gateway to many advance 3D maneuvers..than prerequisite maneuver prior to the piro-flip ... so make these maneuvers the driveway to the gateway of 3D Land.
I have mentoured young and old ... it all depends on your level of commitment, dedication, attention to details and how well you take in advice (given it is properly dispensed). Don't be discourage, it may take awhile to get the hang of it. It took me about 3 months to piro-flip but years refining it. I choose to go with left and right which later helped me achieve more options when transitioning to other maneuvers. Hope this helps, if not ... always free to PM me!
