Yes, piro-flips are very "tricky".

And can be very expensive.............

The hardest maneuver to get over for me was using my right hand to pull my wallet out and enter the credit card number after a bad crash...

but honestly orientation is key, and learning to correct while pirouetting helps alot...

the sim will take you only so far, keep in mind the best learning will happen at the field where pucker factor controls alot of how much you actually advance...

its a risk to model, wallet and ego, but you have to push yourself out of your comfort zone on a routine basis in order to proceed.

showing a preference will only get you into trouble, 90% of everything is crap...

+1 for RM3

Can't beat the real thing!

I think the sim is great for orientation,
Hovering in all orientations, and traveling at various orientations.

I feel the sim fails on 2 levels,
1.Physics (tic tocs are way easier in real life and I suspect it's because of the way air pressure changes around the heli.)

2. As rm3 said, the pucker factor. If all you need to do is hit a button to get a new Heli, then what is your motivation for not crashing? Maybe if they made a sim controller that gave you an electric shock when you crashed?
Or perhaps if the sim presented you with a puzzle to solve before getting a new Heli.

What I've been doing is turning up the auto respawn time, so I'm "forced" to wait. But this is only as good as my resolve not to just hit the space bar.

Goblin! where have you been all my life?

Curt Youngblood did an instructional video a number of years ago. Initially I was disappointed that most of what he showed was the T manuvers, but later realized he hit the bullseye with that advice. I don't think the video is available anymore, but if you know what a T is....

That's exactly how I learned about the "T" basic overing maneuvers and I practice just about every advance maneuver the same way, I think most pilots don't realize how much they can benefit from practicing it.

Piroflip is one I just fail to grasp.
That is one "trick" with too much "turning"

Pirouetting hovering is what you need to master first, all you really need to use is back elevator at the right spot and that depends on whether the heli is right side up or inverted.
