Navio 2 build and first flights!


(Ronildo Braga Junior) #24

Hi ogulbrandsen

First congratulations for your both projects.

In a previous project you did use a “custom” battery. At this new project I think you are not using anymore. Can I ask you what is your feedback about that “custom” battery and why you did decided to not use anymore? I attached the image below.

Warm Regards.

Ronildo

I soldered and built a battery for long flight times out of 20 Panasonic 18650 cells. 4S5P, 17 000 mah, around 930gr. Should give 60 minutes of hovertime.

Hello ,

Ole could you tell us where did you find those landing legs ??

Hi, the batteries works great for slow flying quads that can hover for around an hour. For faster quads you need lipos.

BTW, for my first quad I was using the Panasonic 18650, they have a max C rating of 1-2
I’ve later tried the Sanyo 18650, that are rated at 3-4 C, same weight and mah, These are better if you decide to build your own battery.

The lipo in my lates quad has a C rating of 10. I just wanted something faster and something that had better capacity to lift things (gliders etc). (Racing quad that flies for 5-10 minutes need batteries with 40+ C rating)

I think the Sanyo batteries are the best good option if you are designing a light frame that can hover for 30m+ and where top speed is or payload capacity is not important.

How much is the 4g service?


(Ole) #31

That obviously depend on your network provide, connection speed and dataplan.
I use a normal dataplan from Telenor in Norway with a special APN to give me a public IP called internet.public
(the use of the APN is free with Telenor)

Just a question on this. What is the C rating of your battery pack in that configuration?


(Barry Bolton) #33

It is a pitty there isn’t a step by step guide to this

Hi, the battery is: 8Ah 6s 10c battery at 960gr http://www.elefun.no/p/prod.aspx?v=29659

Ole,
I’ve been admiring your work and have a question about one of your setups. One of your quadcopters ran on a 6s battery. In one entry here you said you provided power to the Pi/Navio2 by way of both the power module and an external BEC. Can the Navio2 power module handle 6s voltage? I thought it was for up to 4s Lipo.
Thanks,
Paul in the USA

Hie Ole…
Can navio 2 can be controlled by rc controller and by internet at the same time ? Like if i want to control it with controller then i switch on the controller and control it ; and after that i will give the gps co-ordinates and it will automatically reach there on its own and without using rc controller.?

Hi Ole,

My name is Lucy and I write for The MagPi - The Official Raspberry Pi magazine. I’m keen to cover your Raspberry Pi quadcopter in our magazine, as a Project Showcase or as part of a feature. Can you email me please lucy@raspberrypi.org. All the best. Lucy

Hi there !

Navio 2’s Compass has only one direction as you know. In this case How did you locate your Navio
according to backward ? How did you set your drone while your navio 2 is in oppsite direction ?
Could you help me ?

Thanks in advance :slight_smile:


(George Staroselskiy) #40

You can just change compass orientation in a ground control station. COMPASS_ORIENT is the parameter you’re looking for!


(Beytullah Durası) #41

I couldn’t find COMPASS_ORIENT Section or where to write. Could you tell me where it is located?


(George Staroselskiy) #42

Open up Compass settings in a gcs of choice and select compass orientation.but I guess you need to change board orientation. (AHRS_ORIENTATION being the parameters to modify)


(Beytullah Durası) #43

Hi! Which Air frame type did you choose for your drone on MP ? I am not sure about choosing V-Tail or Quadrotor x Type of frame on Mission Planner. Thanks for your help.
