You have no idea how much you help me. I like how technically you get but make it so simple. Thank you

[@NS-niws]

saya harapkan di setiap videonya menggunakan keterangan sambil di praktek, dengan begitu saya bisa faham maksud dan tujuannya. terima kasih Mads Tech

[@ganeshcommn50]

Thank you very much for clean and detailed explanation.

[@mallikarjunse]

Hey Ian! You can still hard wire the safety button on Here2. Just match pin-out of switch on Here2 to switch on GPS1 port. Nice video as always! 🏁

[@MadRC]

Yea I avoided this from the point of confusing matters, as you say you can work around it. Tbh I hate the switch.

[@mallikarjunse]

@@MadRC Yes. I hate the switch too. Never used it till now 😂

[@richardcjoy]

Thanks Ian for this video. Planning on upgrading my UAV to the cube so this was very useful.

[@venturarealestate9918]

Great video on my favorite subject! Thanks!

[@mikeb5556]

I don't know why it took so long for me to find your channel. It's clarity and detail are just great and reassuring. Thank you - I have subscribed. I am about to use my first cube (orange) and I am putting it on my custom-build (on an S550 frame).

[@MadRC]

Thanks for the feedback and kind words.

Hi can you do a tutorial of how to put. Ardupilot on a Dji mavic series drone using a raspberry pi or anything else

[@bensonfilmworks7595]

Thank you for a very understandable tutorial!

[@octavianminescu]

Hi. I have the Hire1 GPS, and I want to buy another Herre1. Can I use two Here1, What will be the disadvantage of using Here1 instead of Here2?

[@Hdig892]

thank you for the help!!

[@yonijm]

Hi, I'm trying to calibrate the ESC 40a with the helelink and it's unsuccessful. Know a solution that can help

[@martinkeilloh1580]

more goodness from Mad's man cave keep it comming

[@roberteigenberger5064]

Like your vids, very informative. I'm interested in doing a similar build but I cannot find a frame like yours. Where can I get one?

[@MdFaiyazAhmedRME]

Hey mad's tech, your content is soooo good. I'm From INDIA. Can you please put a short video on your channel on "How to connect L9R receiver to Pixhawk 2.1 Orange cube. I have searched on the entire youtube and didn't found it. Thank You.

[@Cris_Izagui]

Nice. But, when de second gps is rtk, can i set use the second without issues?

[@markgiles8527]

I damaged my gps cable and do you think i could get a replacement? Nope. What I did see for sale was a cable for a second GPS unit. I ordered that cable and it arrived. It is the original gps cable with a couple of wires cut and removed. The the hell! Who's the bright spark that thought that one up? So now no LED on the button and safety switch turned off. No big deal. But just cutting the wires is just crazy if you ask me. Especially when i haven't yet been able to buy that replacement for the Main GPS and have back the LED and Safety Switch.

[@martinkeilloh1580]

Hi Mark,is this the one you are looking for www.3dxr.co.uk/product/pixhawk-2-gps2-port-cable-45cm/

[@aeronaughties]

have you tried amazon?

[@SayantanMazumder]

I am using PixHawk cube orange with herelink, my drone flies well but it dosent hover at centre stick position ,plz help

[@alvaroesosa]

Hey Mad, thanks for the video. In which cases do you recommend using 2 GPS modules?

[@MadRC]

really its down to if you want or feel you need GPS and or Mag redundancy, If I was flying high value payloads then i would 100% be flying dual.

[@MrNams]

I have “Pixhawk 2.4.7 PX4”, when I go to “Mission Planner 1.3.74” then I see there are two option to Install Hardware 1) Install Firmware -It has all Firmware Named as “Copter…” When I select “Copter 4.0.5 Official” then It ask for Platform,Version and Firmware. 2) Install Firmware Legacy - It has all Firmware Named as “ArduCopter…” I am confused how to proceed to setup my “Pixhawk 2.4.7 PX4”. Please help.

[@MadRC]

Legacy is NUTTX Bootloader, you should install the current with Chibios on your controller but Legacy will work as well on that.

[@MrNams]

@@MadRC Perfect, thanks I got it now.

[@gromitvt10]

When blending two Here3 GPS units on CAN is it better to keep them close to each other or far apart? I've got a large VTOL so i can have them close or far apart. Thanks

[@Steva909]

Hi Mads Tech, i constantly get large compass offset params, i dont see where the problem might be.. auto analysis show me that, please help

[@michaelkaplan604]

What is the difference between the Here2 and the Here+ GPS? Will they blend both together without any issues?

[@Rapsaj]

What happens to the craft if the GPS is set to blended and one gps outright fails. Will the craft still function or does ardupilot glitch/do weird stuff when that happens?

[@MadRC]

No it will just continue on the single. Think of blending like a mixer. It will mix the bad one out entirely.

[@shriramsuresh9435]

@Mad's Tech Is it possible to connect Ublox Neo 7m or Ready to Sky M8N GPS Module to pixhawk Cube Orange instead of Here Gps series? I connected the M8N GPS to Pixhawk Cube Orange GPS 2 according to the pin out of both GPS 2 port and GPS module pin. GPS is powered and LEDs are blinking but compass and location is not working. What params I should change? Please help me out. Thanks.

[@halilumutoymak8104]

Heyyy i hope u figured out your problem. Because i have same problem in there

[@michaelkaplan604]

Is there any differences in setting up the prams using 2 GPS’s were GPS1 is plugged into the GPS1 port(serial) and GPS2 is plugged into the GPS2 port (serial) rather than using the CAM ports? BTW I am using the KORE controller board.

[@MadRC]

Basically serial just works. On Can it’s just enabling the CAN and set the GPS 1 or 2 to CAN based.

[@PX7A4060]

Wouldn't energy consumption increase with 2 GPS?

[@kickfliph]

Hello there, Excellent tutorial. Question: I have a Pixhawk 1 and the internal GPS was working fine, but now I'm unable to have it fixed, is not picking up any satellites, I have not changed any configuration or parameter in the Pixhawk I have been flying it in open spaces trying to pick up any satellites but with no luck. At this point, I have no clue what can be happening if you have any idea that can help me figure what is happening I'll really appreciate it. Regards,

[@MadRC]

The original Pixhawk does not have GPS built in, has compass. Do you mean pre Pixhawk 1 ?

[@kickfliph]

@@MadRC Thanks for reaching out back. Yes, you are right!, the Pixhawk only have compass I mixed all up sorry I'm just a newbie :) now, I also have an external GPS/compass module connected to it, I have check the connectors port and I believe they are correct, the GPS in the serial port label "GPS" and the compass in the one label "I2C", in this point I believe that this external module is broken or not working correctly I crash the copter days a go and the GPS external got badly hit, maybe that's the reason why now it's not working. I'll order a new one once Install it I'll let you know how it went. Thanks for all your help.

[@kickfliph]

It was the external GPS module, I got the new one and now everything is working as expected.

[@michaelkaplan604]

When using 2 GPS’s can you set one up on the serial port and the other one on a CAM port in blend mode?

[@MadRC]

Yea absolutely

[@aeronaughties]

anyone working on a 4g link for pixhawk?

[@johntadley4323]

Hi Mad man , what would be the best solution to have gps set up sending information over bluetooth .any videos you recommend, im new to all of this .don't require autopilot just the gps position that will show on an app for bait boats

[@MadRC]

Ahh ok a man after my own hart. I used to build bait boats and used many over the years. I used to modify some of the Angling technics ones like the Microcat and Procat. In fact an little thing you may not know is my user name on many forums is Mad_Angler1 for this very reason ;). I see a nice mirror there. Ok down to business so you want to haven your location, the best way you can do this is get an a cheaper FC with GPS and WiFi module to transmit. While you may not want to go full FC use there are lots of benefits such as waypoints and the ability to send it back to the same place. Sadly you can’t just transmit the GPS from these controllers as it’s pure GPS data.

[@johntadley4323]

@@MadRC thanks for the info , I will be using an app (carp pilot) that accepts wifi or Bluetooth. Wanted to use bt740-sc as my wifi is tied up using a raymarine on the boat . If I connect the tx of the fps to the txi of the bt740-sc would this work?

[@aumgnfeig9367]

Why does Hex only sell GPS units with IMUs and processor boards, when all their flight controllers have triple redundant IMUs anyway? Seems like a waste of money.
