"I see, I misunderstood owing to H2, which mean hydrogen in chemistry.
All up weight (AUW) means total weight of your drone. I will take a look on your website. Thanks a lot"

"Even non-Solo items shippable to non-North America cost too much, Shipping cost as more than the item price.
No choice for shipping method. I paid 108 dollars shipping cost for 91.16 dollar of IRIS+ parts and 2 LiPo."

A Gas engine and generator provides DC power, is it correct?
How powerful gas engine is using in the quad rotor?"

"Thanks Philip
I have ordered IRIS+ and some parts on Feb 28, but it is still in process for shipping. No shipping track available yet.
It says 'Solo only ships to US and Canada.'
What I am missing?"
