50 MINUTE flight with my cargo drone video (with only a 3s 5200 mah) AND WITHOUT THE CARGO BOX

Hi guys, there is my video test showing my first flight time test with my cargo drone, I get 50 minutes with a 3s 5.2 Ah, if you want to stay tuned about the project sign up the newsletter http://eepurl.com/cUJnJr  or just take a look to my site https://www.sandwichdrones.it/

I had some problems to upload the video without the speed 10X cause it was about 7 Gb, if you want to send me a pm and I will try to send it to you.

ps. a future prototype will be a hybrid so stay tuned!

I smell hoax 


With somewhat similar setup (3.2ah, I'm not crazy enough to parallel it with 2ah)  I get 15 minutes (quad w/o battery weights 1kg). 18 minutes with 4ah. 
By going seriously efficient I could hope for 30 minutes, but 50(!) - that's a completely different level where every gram would count, custom battery pack etc. (the level which is magnitude of order above "paralleling different capacity battery packs!")

I got about 54 minutes on quad with 3 axis gimbal and 10" props. But it was a custom made carbon frame and a custom made LiIon 4S battery:

Sergey you got an amazing result, what about Mah? , what is the frame only weight?
