"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 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…See More

"Too true Andrew, hard to go past a heli if you need payload, ability to handle wind, endurance and vtol."

"@Gordon, even if it has a box it still isn't a 50min cargo drone because cargo has to go somewhere, not hover in the air.  This is the Achilles heel of multirotors where power consumption is at its lowest whilst hovering and rises from…"

"okay, if you look in previous comments, I said that the quadcopter with the cargo box is 1500g during the flight there wasn't ANY cargo box so the quadcopter flight weight was 1200g, a part of the changes I hope will be used in a future serial…"

"Nicolai, your saying that Graham has added 280g to your weight. Graham is in fact being generous, you have already stated the weight is 1500g. This means each motor must produce 1500/4=375g just to hover, this does not even allow any extra for…"

"you made this calculation by adding 280g at my flight and reducing the battery at 4.1 mah from 5.2 and not considering any modifications, but okay "

"That sheet states 23W at 65% with 13x4 prop for 370g thrust each motor, that's 92W for 4 motors for 1480g thrust. 92W / 11.1V = 8.28A which only gives 37mins using 5200mAh or 30 mins using 4160mAh (realistically 80% of 5200mAh). That you…"

Please tell us a bit about your UAV interest
I love everything that can fly, I started this hobby in 2012, and now I'm working on gps fully autonomous quadcopter,I want to create something that can help people in every day actions like carrying things.

New frame for my cargo drone and upcoming 4KG PAYLOAD test

Posted on July 17, 2017 at 12:30pm 2 Comments

In these days, while waiting for the waypoint navigation hardware, I'm working on the new frame for my cargo drone, and on the new box, I'm also planning for 4KG PAYLOAD test, after the first of 2kg, I've now got 580kv motors so I have better a thrust, if you want to stay informed on this project please subscribe to the newsletter: http://eepurl.com/cUJnJr  or take a look at my site: …

2 kg Test of cargo drone

Posted on July 9, 2017 at 1:00pm 4 Comments

Hi guys, in these days I made a successful payload test of my cargo drone (it's just a few seconds but it demonstrates that we can do it). Another news is that I'm working on the cargo box so I changed it with a more resistant one and now I'm working on the navigation system (based on waypoints).  ( sign up to stay informed on this project http://eepurl.com/cUJnJr   or visit our site  …
