Kevin, first please join our FaceBook forum for 350 pro support https://www.facebook.com/groups/711455455567160/

From what you are saying, its my impression your GPS is working, but the radio is not setup correctly. the box come with a setup sheet for the radio, that will walk you through checking the settings, but hop to the support forum we have already answered this many times, and there is setup documents in the files section. :-)

I have set everything up checked and recheck...gone thru all steps over and over and having issue with GPS hold, RTH, round flight etc. None of these work. I'm getting 4 flashes showing good Sat coverage but the copter flies away in GPS hold, Return to home does not work copter just floats away into the distance. The radio settings were set up by Walkera. Any thoughts on what issue might be. Being new to this it was GPS hold that sold me on this unit as I felt it would be a great help learning how to fly and how not to crash. Thanks in advance for your help. Kevin

Bo Lorentzen

Hey Rory, you need to go into the menu and toggle through the video channels to find a channel with the video on. ;-)

Rory Hewitt

I just took delivery of a pro F7. my controller just has blue screen and does not show video and the iLook when connected just points straight up 90 degrees? Very frustrated! I am very new to flying and have no clue with settings on the controller. Can i get a file that will set all the settings?

Kevin Smith

Just wanted to say many thanks to Bo. I just purchased QR X350 pro with Devo F12E and I'm new to this hobby. Bo your vid's were a great help putting things together as well learning functions on controller. I have set everything up checked and recheck...gone thru all steps over and over and having issue with GPS hold, RTH, round flight etc. None of these work.

Hey John, I really don't recommend modifying the radio to center the throttle stick. I know some people have done it and some like it. but here is the thing, if you arm the 350pro and the throttle slip from you, it will instantly jump to 50% throttle. thats cool in the air while flying GPS, but not while sitting in manual mode on the ground. Until there is a significant "philosophy" change in the setup of the APM controller, its not worth changing the stick.

In the figure, as GPS supported flying become more and more the standard, center stick will probably be the standard for most products, but this require the software be written around the center stick. ;-)

Hi Bo, I like your instruction. I have a 350Pro with the Devo 10. I recently updated the quad from the Walkera site. It appears to be flying more stable in manual as well as gps. Do you have any opinion on setting up the left hand throttle to auto return to center position? If possible, would you have to change anything in the radio program beside removing the screw that allows the spring return to work the throttle? How does the phantom quad setup accomplish this position?
Thanks, John I live in Southern California, Thousands Oaks area.

Bo Lorentzen

@Byron, you need to go check out the Facebook group. here https://www.facebook.com/groups/711455455567160/

However. reality check... DO NEVER try to change low-battery-land to auto return to home... if the quad is about ready to land because it is out of power.. its a really bad idea to make it try to go home instead.. that is why it is auto-land on low battery.

Bryon

Hello, and thanks for the great information!

In the original post you mentioned:
1. turn off the low-power auto-land using any laptop. Gektor instructions link here......

but there is no link

This is the link i currently seek - how to adjust the low-power auto-land? Along these lines, out of the box can we change auto-land on low power to auto-return-to-home or does that require Mission Planner upgrades?

Bo Lorentzen

Hey Doc, you need to make sure its connected inside, but more importantly, the cable is probably missing, you need a long servo cable, plug it into AUX2 and then plug that cable into the fat cable you find in the kit. that is the start-stop control cable for the iLook+
Post the question on the FaceBook group I linked you to before. :-)

docBaliman

thanks bo! that's just exacticly what i have been doing for the past week...searching support forum on the net, but no luck so far...try my self to use the AuX thats normally assigned for starting stopping the camera, but nothing... so, if you have time-2-spare on any given sunday, besides watching NFL, I would really appreciate your help if u drop me a line -or 2- ;-)

thanks!

Bo Lorentzen

Doc, you need to pick a channel, like using the AUX thats normally assigned for starting stopping the camera. then you can use the switch on the remote. Its a bit more than one can explain in a blog post. you probably need to check out the 350pro support forum on FaceBook ;-)

Doc Baliman


Hi. There bo! The doc again!, i need help installing a simple and common micro servo to my walkera qrx350 pro. This is The second one (i take ur advice and buy a BNF brand new) and im installing a hand-Made parachute system, and i need to add a servo mechanism in order to make The parachute open!

I have The devo F7 controller, and The DEVO-RX703A receiver...

Can you please give me a hand? Thanks!

Bo Lorentzen

@ Sets, you need to follow the F7 setup instructions on the DVD that was included with your x350pro

Sets

hello,

i have a little problem in this model.

i bought one qr x350 pro and "DEVO 7" kit, then i bought walkera online site "DEVO F7" radio but unable to configure it.

do you have any config file or tutorial devo f7 configuration for walkera qr x350 pro?

thanks.

Bo Lorentzen

@ Doc. don't know what to tell you. the props on the 350pro have a anti-rotation design, they can not rotate, that means they don't loosen the screws during flight. accident investigation would have to conclude that the prop nuts were not firmly secured before flight. remember to check props before each day you fly. stuff happens.. they can be shaking against something in the back of the car while driving etc....
And STICK TO stock props, Matt & I have tested them a lot, the stock props are great props for the money. ;-)

That out of the way. Personally I would probably just buy a BNF 350pro, the $329 is a great price for anything that files. ;-)
BTW. keep in mind the controller, ESC's and motors, probably all work, and you can use all of it on a FPV build later if you like. or put it all on a cheap flame-wheel 450 frame.

Bo

doc Baliman

thanks bo!! unfortunately today i had a bad day...one of the propellers fall-off in middle air, and the quad came down like a rock!! crash & burn... Im still with doubts if I buy a new drone (339 usd), or buy each one of the parts separately and assemble myself, since the MAIN CONTROL ($229) apparently was not damaged….
WHAT DO YOU THINK... had to pay my newbie status on this!! :~)

Bo Lorentzen

Doc, check out one of Hobby King's self contained OSD's cost about $50. there are many systems on the market. these contain a GPS and a voltage monitor, you need to attach the gps and then run the video cable from the camera to the OSD, and then connect the video out to the VTX. finally you need to plug the power to the battery terminals so it can measure the actual voltage of the system.

doc Baliman

hi there bo!! when u say: "you would need to put inline a stand-alone OSD system. which is fairly cheap really."
can you please orient me where i can find this online for my walkera? thanks for all!!

Bo Lorentzen

Hej Joe, there is a CD in the kit, that one have the manual for the x350pro and also setup guides for several of the different DEVO radios.

Joe

Bo You were correct about the two pots on the gimbal. Thank you for your help.

Would you happen to know a good place to read or watch the set up for a Devo 10 and QR X350. I want to scroll through and confirm all of my settings are correct. Thanks again,
Joe

Bo Lorentzen

Hey Doc. In the current incarnation, the 350pro do not deliver GPS info.
you would need to put inline a stand-alone OSD system. which is fairly cheap really.

doc Baliman

HI THERE BO!! im from Chile, so first my English is not too good. I'm wandering if it possible to get an ALTIMETER MEASURE on mi DEVO F7 CONTROLER (with screen) from my QR X350 PRO? I would like to see in the screen how high i'm flying... thanks!

Bo Lorentzen

Hey Sarge, I rewrote the quick-start guide. link is on the top of the page.

Sarge
