Commercial use of drones in farms and other agriculture
Hexa with Hobbywing X8 motors
Hii am building a hexacopter with1.) hobbywing x8 motors2.) flight controller pixhawk PX53.) battery 12s 22Ah4.) wheel base of around 1800mm5.) estimated weight around 17kg without payloadi am looking if anyone has already tuned this type so i can get a head start. looking forwardthank youMike

That's great - perfect for my fixed wings! Go Tesla ;)
You should say that the NCR20700A cell at 20A has his capacity down to 2800mAh
and the rated 3300mAh capacity is only for 0.5A load.
These cells are not for heavy UAV but for ultra efficient UAV, it is a different thing.
Cristian , I have work with Li-on batteries and I do not completely agree to what you wrote about.
- These are not "real" 6S packs since the maximum tension of Li-on battery is not the same of Lipo batteries, look at the graph belòw , the blue line fit best scenario.
- The pack capacity in real world is not 21Ah , looking at the datasheet by Panasonic it is quite clear that the usuable capacity correspond to voltage low as 3 volts, so lets say 3100mAh if you have 1C discharge rate, blue line.
These type of batteries can be used on drones with very high efficiency and low Ampère draw, should be around 1C during hovering so 2C during normal flight.
I have done some maths , and the example you gave with 70' flight 5kg AUW works only with a quad with 26" propellers and a 1200 grams payload.
Copters with "normal" props around 15-17" will raise the Ampère drawn and make these batteries type more and more difficult to use because of their maximum 3.1 C rate of discharge.

Got all that you need.
As you, we are passionate about drones and agricultural applications. At the moment, we have developed a low-cost camera that would let you know about health of plants and crops through NDVI multispectral analysis. The good news is that we will launch it by a crowdfunding project in Kickstarter. Here there are the main features of uSense camera.
To drive our product to the right market we would like to know your comments and thoughts regarding the next questions:
1. Type of uses that you will do it with a camera like that.
2. What are the features that you will love add it?
3. How much you will be willing to pay?
Thank you for your comments, we appreciate the time and any link that you think could help us as well.
If you want to know more, don't hesitate to contact us!
Cheers,

Hi Silvio
@Martin Hill Compliments, your LED is amazing! What flight controller do you use? we're super interested in testing that vehicle with VOLTA 4Gmetry (http://diydrones.com/group/volta) - write me silvio@voltarobots.com and we will arrange something for sure! Once again, it's one of the most interesting projects I've seen here!
1 hr Endurance, 3-5 amp battery, 400g payload, camera gimbal, FPV, Low vibration, crash survivable, Helium recovery and storage after each day of use
All for <£1000

If anyone is interested, I'll process some imagery for you using Pix4d. I'm not setting out to be a data processor, but I'm spending a lot of time in the program and just finished setting up a new server for processing our images.
The weather is crap right now and I'm tired of playing with the same old data sets. If you have some you'd like to share, upload the unedited files to drive/dropbox and PM me the link.
