Long range UAV link 100mw for 60KM was designed and tested

@Tom-fly are you aware of the issues with Pixhawk 4 and SBUS signal ? Check out the thread below before having a mishap. I’ll prowl into my P4 later on, searching for the means to disconnect the DSM path from the input pin.

No I wasn’t aware! that seems to be real naughty problem. I have used pixhawk 4 couple of months now and I didn’t have similar problems. But it is good to know that issue, thank you for informing! It is possible hardware combinations generate issues is different way.

Nice, Im shure you test Argentine beef too :wink: .
Yes I love the idea to have an specialized drone radio for diy entusiast like closed rtf , I appreciate the rubbers stick dust protection because I fly in dusty conditions so Im going to give them an oportunity, perhaps more difficult to use in our mode but not impossible?

Yeah looks interesting. For some reason however they don’t want to ship to Canada. So I hope the one I ordered got out of the country before I ordered it. I suspect it has something to do with the Postal Strike we had. Thats now been resolved but my guess is it was cause of that.

Well my overhaul and move to the Skydroid is getting closer to being done.
I just need to sort out the GPS connection and then calibrate the machine and maiden with the Skydroid system.
so getting there.

This should be fixed now in 3.6.3-rc1

Has anyone pulled the distance test?

Almost there, gotta do some ground tests. I moved Pixie and R12 to bigger platform.Btw, what is optimal antenna position for R12 ? In the last picture there are antennas pointing down…

Looking good Tom.
I have mine almost there. I solved a GPS issue this morning. Tossed in in the garbage and replaced it lol.
All thats left is to setup the OSD connection to the FC. Then I need to do my calibrations and then complete a few tests. Make sure the FPV video is working and then done.
That will likely be late tomorrow or Monday. But almost there.

Thank you for reply! You have already pushed M12L abroad and pretty succesfully, almosts all the continents has users for M12L so it has already covered world. We will make presentation tests and evaluations and M12L and its successor will gather popularity in uav/drone-family. I really like concept of M12L, it is very compact and easy to setup. And It is also very stable as well.

Poor gps, It has served very well so retiring it is very good choise. I’m currently using RC Chibios in pixie4 due problems informed, hopyfully that works. Usually betas aren’t very stable, knock knock.

yes, I installed that to pixie, usually betas and rcs aren’t good for serious usage. Lets hope it works…

Here a photo what I recived, Im impressed that all improvements comment in this topic where done :open_mouth: .Phone support is metalic and looks indesructible, I recive the two Rx antennas, the yagi, mode 2, and removed sticks rudders, first impression was high quality unit, I appreciate left joystick trim too, the 3 point in all switchs and specially small size with integrate telemetry too

The bracket can be rotated.

The copper tube of your antenna is far away from the metal and carbon fibers, ensuring that you can see one of the antennas directly when the aircraft rotates to any angle.

I hope someone can use the fixed wing for long-distance testing, because this product is not only convenient, but also more characteristic of long-distance testing

I can do a review like this on my channel if you still have any available for that. Here in NZ now we have warm weather and 15 hours of daylight :sunny:

I live on a large farm so I can test up to 3km at home, longer than that would have to be over ocean. My plane can’t travel 60km out, but 20km should be possible.

I noticed in my test of the FlySky there is a big difference between the distance the receiver can still receive some control packets, and the distance at which it is smooth to control. If you’re not manually controlling it every now and then you don’t notice this difference. Was your 60km test just in cruise mode and RTL like my test was? Did you have a ‘long failsafe’ type timeout that would enable the flight controller to keep going even when no signal was received for a few seconds? Yeah, I am still skeptical of the 60km claim :slight_smile:

Judging by the tracking number I should receive mine next week, if that’s the case I’ll put it on my 2+ hours endurance plane and see what it can do range-wise.

I read that 45 degrees each antenna was better, be shure that anything shadow signal with radio control, batt too.
