It is entirely possible... negative pitch is used in only in a few helis and the amount is very small. The redbull helicopter is another stunt copter

 

Possible even if they just went to neutral collective while inverted if roll rate is fast enough.

 

bump

 

Actually note how the flight path is a high arc and at the peak they perform the roll? Maybe it is only neutral. If i were flying real helis i would love negative pitch (i think)...

 

Must have upward momentum to sustain altitude while rolling inverted. Inertia does the work where there is no negative collective.

 

That's normal here in Auss. lol

 

Yes we play hopscotch with the lightning on the way to work or school...

 

Ha ha ha... very true storm! Thanks for looking out for us you could have easily destroyed that car! Apart from Stom and Crash Heligod, these are other things you can encounter while living in australia....there are many more....

 

Ah. I was gonna say........ no Drop Bear??

 

We definitely get ours up here. I think I've already discussed our tornadoes.

 

Yeah tornadoes are scary! We get cyclones up north and there was a single tornado just last month. But NOTHING like what you guys get.

 

We had a seasonably unusual outbreak of tornados about 300Km from here last week.... big ones! And now there could be snow in the forecast. It's said... If you don't like the weather in Oklahoma..... wait a minute.

 

Well in Melbourne Australia its traditional to get 3 different seasons in one day. We can have hail in the morning and within an hour be pushing 20 + Degrees. And i have also seen the wind change directions 360 degrees at various times through the day. Amazing.... sounds like Oklahoma might also be a bit like Melbourne...

 

Being that were both situated on almost exact opposite sides of the planet and in latitudinally similar zones, I suspect our climates are similar, only on opposite cycles.
Getting nice and warm down there I bet.

 

Today was wierd.... severly overcast but around 29 degrees. It is warming thats for sure but over the last many years its been rather cool over summer comparatively. We are getting prepared for 44 degree days - we usually get a few over summer. Flying in 44 degrees will stress test the 380 thats for sure!

 

I had no idea anyone made these!

 

I want to attach one to my ceiling fan! I could sit and stare at it all day.
