Just sitting here at work imagining how to do a piro flipping auto..

Anyway, a lot of people piro nose left during aerobatics because its not so demanding on motor power (im not one of them)

Now correct me here if im off the mark but during an auto is the helis natural tendency to want to rotate nose right??
therefore to use less energy from the disc it would be crucial to do aerobatic autos while piroing right where every peco joule of blade energy is important???

Im thinking about ASz's freestyle flights at 2004 3DM where he pulled off a nice chaos auto but i cant remember if he changed from his usual piro left methods.

Anybody got any thoughts on these lunchtime musings??

When you do a piroflip with the engine, it is easier because you unload the engine when you do it with left piro. With a good tuned engine, it is no that big difference. Curtis usually piroflip with right piro.

In an auto it saves more energy with right piro, so you are completly right about that one. You can do it with left also, but it is a little more energy-saving with right piro.

But if you are much better at left piro, than right, I think that left piro in auto would be the best, since you are better at pitch management etc in left piro.

Just my thoughts.

i can do piro flips just fine to the right, and to the left, well, they dont look that great to the left, but i can do them both ways...i can also do piro flips within 20 feet of the ground no problems, and keep it in one spot...but when i tried them in a auto...boy its alot still trying to learn how to do them correctly in a auto...i usually slow the blades down to a nice slow rpm..probably around 1000rpm's and its hard to get use to such a slow head speed while doing acrobatics..but as they say, practice makes perfect.
