| ptarp,
I've looked at your recording, your problem (which is the problem for most of newcomer to Piroflip including me when I first attempted this maneuver) is that you are trying to match stick input to heli movement, or break down the maneuver and try to interpret heli orientation and give corresponding stick input. In most of the 3D maneuvers, we have to do that, but for PiroFlip, in my humble opinion, that concept is very wrong!
In Piroflip, the most important point is to match the piro rate with your stirring speed (there are other things to make good piroflip, but as a newcomer, this is it). I always told other fliers that once you decide to
start Piroflip, the only thing you have to memorize is how fast the tail piros and just continue stirring the stick with the speed and DON'T look at the heli, I can even blindfold myself and continue doing Piroflip for a while (on the sim of course)! On the real heli, I can even do it even it is very dark, because I don't have to know what the heli movement, as long as I stir the same rate as it piros, heli itself will find its way to flip back and forth (with good control of the collective and different stirring radius, but that's advanced topic, you can kind of ignore this part for now).
As a first step, you can practice piro hovering, both upright and inverted, you can intentionally give wrong input and try to correct it back to stantionary piro hovering. Once you are comfortable with this, that means you memorize the piro rate (so that you can correct it back), and the next thing you have to do is just KEEP stirring WITHOUT paying too much attention to the heli!
We have a guy here trying to practicing Piroflip, he is a Mode 1 flier and we tried to convince him to convert to Mode 2 by showing how easy it is to do Piroflip with Mode 2 compared to Mode 1 on the simulator, wiht one guy controling the collective stick, we just told him look at the heli like it is other people flying it and jjust keep stirring. In ten minutes, he could do OK piroflips (of course with one guy help on the collective). Within that ten minutes, the only thing he tried to adjust himself is the stirring rate!
My suugestion
1. Do NOT break down the maneuver!
2. Faster piro rate is actually easier than slow piro rate, to start with make roughly 1 rev/sec
3. Number of piros per flip isn't really that important, and I found myself that doing several piros per flip is easier and prettier. I think your stirring is too big (remember the stirring radius controls the number of piros per flip). I only use roughly half or even smaller of the full stick to do piroflip (I don't use dual rate, only one rate for everything).
4. First start a piro for several turns and then start stirring, so that you can know the prio rate
5. Fly higher, so that collective control is not that important to begain with and you have enough altitude to let heli drop.
6. DON'T try to interpret heli orientation, look at it just to decide the timing for collective.
7. Once you start, DO NOT stop!
8. KEEP stirring like an idiot!
9. If you still have problem besides losing altitude and crash, adjust your stirring rate! |
