How to learn to hold a constant piro hover
Did my first nose in hover today first with my 450 then my 550. Overall it felt pretty good to break through that fear barrier and it is acually not that hard once you do this (the practice in phoenix kicked in once the fear went away). It was so much easier with my fbl 550 (I think I will definitely convert my 450 to fbl now).
Anyway I want to start learning to hold a constant piro hover on the spot. I am crap at this in phoenix and not confident to try this with my real helis. I gradually get more and more out of control and can't correct unless I stop pirouetting. Does any one have any tips about how to learn to do this?

Try it a bit faster first (but not too fast, 4-5 seconds per piro) and correct when it's tail in/nose in/side to you. You can stop for a second in each of these orientation as well.
Other than that, practice and and don't give up - it will come and it's worth it, it will teach you a lot.

It's just practice and as said, don't be afraid to stop at each "quarter" to correct.
Personally I have found that breaking each maneuver down into chunks makes it a lot less overwhelming and easier.

Yep- just practice tons and you'll get it. Like a lot of techniques with flying helis, eventually it will just magically click and you'll wonder why in the heck it was so hard to learn.

Thanks also. On Phoenix, there's nothing to it for me. Just give rudder and viola but in real life, it doesn't work out as well.

id recommend upping the setting that makes the heli less stable. i forget exactly the setting but in there somewhere you can make the swash more randomly unstable. more realistic that way.

Adding random gusts works as well.

Or get a mCPx, I can hold my Trex600Pro in line pretty easy, but the mCPx is all over the place, I figure when I'm able to keep a steady pirohover with that thing, I cant do the rest in the blind

I'd suggest you look at how the heli's attitude matters in a hover and how that attitude changes constantly as you pirouette.
Let's say you start with tail in. The heli is tilted slightly to the right to counter the sideways drift. You yaw clockwise 90 degrees. Now here's the Big Secret: The heli will not be tilted right anymore but forwards, resulting in a left/forward drift. Why? When you yaw the heli, the mast will not change its tilt direction (sufficiently) but will remain its tilt direction. Rudder has (next to) no effect on tilt, that's where the cyclic enters. So, you started with the mast tilted to your right. You yawed the heli 90 degrees and the mast will still be tilted to your right while the nose is also pointing to your right. The tilt is therefor forwards. With no right tilt, the sideways drift will kick in again too. You need to constantly correct the tilt to keep the right tilt while keeping the tail-nose axis horizontal. The tiniest cyclic inputs will do. For a CW yaw, you need to add a tiny bit of back/right cyclic. Back, to cancel the upcoming forward tilt and right to add the "new" right tilt. For a CCW yaw, the heli will end up with a backwards tilt and no right tilt so: A tiny bit of forward/right to cancel the backwards tilt and add a "new" right tilt. Now, this is simplified a great deal. The heli will not be all well behaved so you will need to correct and arrest any drift constantly but, I hope this can be a starting point. The key is to be ready for the changing attitude and to make tiny corrections all the way. Some say start fast, I would say start slow. Start so slow you have time to observe and react and last but not least, to understand why the heli wants to shoot off once you yaw it around. In any case, keep practicing and good luck.

.....make sure your COG is good - forward / back and left / right

I've been able to do piros on my MCPX. Well, at least until it got suck away by a strong gust of wind. I did notice my orientation was slight off neutral. |

Thank you. Your observations are what I noticed in real life and why the my heli has a tendency to drift to the and pitch downward on a slow piro. I had thought the problem was the piro was too slow and more rudder would fix that (at least that's what I do on Phoenix). But, it looks like it needs a little bit of cyclic adjustments as well.

Ha! Same here. So easy on the sim. In real-life it starts to drift.

I learned the same thing by accident when learning on my FP heli. I vary the amount of back/right or forward/right cyclic based on how fast I'm doing the piro. I've done it on my CP doing fast piros but not really slow ones. Would it be the same principle?

+1. Thanks for the great explanation, LN400.
