- Akk recently released some extremely high powered VTX's, going all the way up to 10W. So it only seemed reasonable that I'd have to try one out (actually 2, as I also had the 5W version)

As you say, power isn't always the answer. Propagation characteristics of radio signals at specific frequencies are not going to change just because you are 'shouting louder'.
3GHz and 10GHz are used for maritime radars as they love to bounce off objects. Our VHF sets are supposed to be used at 1W for everything except emergency comms (25W). The propagation difference between those modes is barely discernable. The reason you have a higher power option is to try to drown out interference (other transmissions on the same frequency), it isn't suddenly going to start acting like an MF/HF signal.
I wonder if your home arrow was having issues because you were unable to go directly forward to begin with. • Notes from Betaflight…..without a compass, the quad 'learns' the heading of the quad from the direction of travel over ground from data provided by the GPS. The craft must be travelling at least 1-2m/s, in clean nose-forward flight, for at least several seconds, before its attitude can be correctly determined from GPS data alone. Always fly dead-straight after take-off, in clean pitch forward flight. If it is windy, fly directly into the wind, or directly with the wind, so that the flight path over ground matches the orientation of the quad.
Check that the arrow rotates and points to home after short period of straight flying like this.
Typically some 30-50m distance is required. If not, return, power cycle and try again.
Yeah - I kind of read it. Obviously BF wasn't ever designed to run on a car, and I wonder if simply adding a compass will give a proper direction. Which I might try on the 1.2G setup
@@CurryKitten I was wondering if you could just push the car along or hold it in your arms for the first couple of metres in a really straight line, and see if the accuracy is improved maybe? Worth a try before you swap out to one with a compass.
Reminds me of my old 100w CB Burner....
I found my old 500W 27Mhz burner out the loft still got it ...
@@mabbs2757 The good old days.
The best option for ground vehicles, analog vídeo is 1.3ghz and ELRS 915mhz. Using This set up I can get about 1km range . On the ground 10W 5.8ghz with obstacles it's the same of 5W or 3W. Of course digital has pretty good range but maybe not the same of 1.3 analog
Not sure if you watched it all the way through, but this was a point I made and the future of the car.
put a small compass on hood hahagahagahagaa AKK video is not as good as Rush Fov or speedy bee 800w Vtx ,, I use the speedybee 800 =w most the time without heatsink ,,super dependable last for years or the rush tank 1/6 watt with built in akg mic
@CurryKitten yes, BF AIO works!
Have a look at some of my vidoes, where I used a BF AIO to provide the arming signal to the Vista and O3 on my EDF and plane.
Kinda expensive way to use an AIO for just for the arming but it works!
I previously used it on my 64mm Rafale with BF AIO and Vista (crashed and burned last year) and recently my PA-18 Super Cub with BF AIO and O3. Had an 80mm F/A-18 with Inav with O3 but removing it and just using a BF AIO soon.
Very interesting idea indeed... I'm going to try something like that with rc cars! 😃
Interesting - so the Vista & O3 need an arming signal... to presumably start recording. There's a setting in Walksnail where you don't need a signal - I figured DJI would at least do the same. I have to say, that if you are going to put an FC in your planes for doing the arming, you might as well run iNav and have some decent OSD & flight modes? Whilst I find iNav a pain for rovers, it's pretty easy for plane setup
@@CurryKittenI’m new to Inav but it is more of a pain to fit the large Inav stack in a plane and getting the CG right with all the camera, gimbals etc, unless it is an AIO (not many AIOs are supported by Inav unfortunately).
What I found so far, the Vista can be powered without a signal (just turn off the low power mode option) but the O3 would need a signal (or get a Seeeduino to provide the signal but no OSD). Also, not all Inav OSD items are supported by the O3. So currently, I’m now using an O3 which gets signal from a BetaFPV SuperP 14Ch ELRS via a cheapish GEPRC G4 AIO.
I was thinking maybe trying a SMA Male Antenna Extender Cable Adapter Jumper RG316 20in 50cm would get that antenna up higher and definitely get better video reception
All that green foliage is like a giant signal sponge on 5.8G... The 1.2g setup should be better on far less power....🤔😏🇬🇧
Agreed - this is pretty much what I expected, but was in part for people that think you can just throw power at something to fix it
A much better test to do on the ground if you don't have a ham license😊
Does anyone do a 10w vtx in the 900 meg range? This looks like it would be suited for flying low over forested regions, or through the trees, or through obstacle courses without many drop outs.
BF needs to travel in a straight line at a certain speed before that arrow works. Not sure the minimum m/sec but a car should be able to do it.
Yeah - I'd read this and thought I have enough speed to do it. The GPS I'm using actually does have a compass in it (although not wired) but I'll have to check if betaflight will actually use it for the home arrow
@@CurryKitten Lots of improvements in 4.5 too.
@currykitten, nice video. But it's not for me because of analog.
Is there a way to do the same but with DJI digital products? (i own a set of goggles 3)
Maybe mount a DJI Neo on the roof and test if that is a great way to have a mini drone and a ground FPV performer?
I understand. I was out flying yesterday and flew 2 analog quads before flying on Walksnail. It's when i wondered to myself why I was still flying analog :D Yep - just stick a DJI/WalkSnail/etc on the car and go that way. Again, I wouldn't expect particularly different results as 5.8Ghz has issues penetrating stuff like trees but the view would be a lot clearer
Cured me of ever getting nostalgic for analog FPV. How did I ever fly with video quality like this?
I find analog ok to fly... unless I've just flown on digital before hand and then I think everything must be broken :D
Immersion RC used to make the easy OSD... I have a few of them from the past and they still work for analog just fine
Well there's a blast from the past. As I mentioned I did think about using a older OSD, but I wanted to see what my smartaudio power was doing - that would be missing from the old stuff
i use a 1 watt rush tank in my crawler and can go 600 yds to woods clear but go behind my shop ,, terrible
Yep - 5.8 just doesn't like things in the way!
Great job CK ... Just a thought but how about trying it in a boat water is flat right ?
Water can be flat (unless you have waves) it's also very wet though - which doesn't play nicely with electronics. Would be something fun dto do, I wish there was a really nice flat large lake around my way, but instead we have quite a rough sea
Just a quick question? Why did you not mount the camera on a type of tower on top of the vehicle? That way you can see more of the ground you’re about to traverse in front of you rather than a “ Mouse In A Cornfield” viewing perspective?🤷🏻♂️
Whilst I don't mind something on the roof of the car, putting a large stick that really gives you a 3rd person view driving experience feels like cheating. I like the drivers POV, even if it's not that useful sometimes
@@CurryKitten I understand your point of view ( no pun intended) you wanted to go with the ,”If you were shrunken down to the same ratio as the RC vehicle how would it drive” scenario. I get it.🙂👍💯
Drone with repeater in the sky distance savior
Yeah - it's a nice way of extending range, but wouldn't be appropriate when we're looking to see what the increase in power can give us
You are mistaken that is't a VTX that's an Ofcom alert device.
Unless there are crews of ofcom people randomly souring the woods and fields - I think we're ok for this testing :D
@@CurryKitten yeah your not harming anyone where you are plus’s your on the ground worse possible transmission situation
Fantastic ride and testing, Wayne! 😃
I've never tried to run over big grass like this... It's really hard! 😬
I've been far, but I don't have much idea of how much, because I've never used a GPS... But it definitely sounds like a great idea!
Anyway, stay safe there with your family! 🖖😊
It is hard isn't it. Anything involving being that close to the ground it really quite difficult!
@CurryKitten There are 2 things that might help: putting the camera over the car, instead of inside of it... And a servo gimbal. Because then you can look up, down and to the sides.
i use a caddx ant aio camera on 2 servos to fpv crawl
I would have a pan tilt setup in this car, but my view is pretty restricted by being inside the cab
Camera on a stick would really help you out with navigation! Great fun video. I want to make a betaflight truck now!
Perhaps I should carry a small quad on the rooof so I can take off to inspect my surroundings :D
Looks like great fun. Thanks for the show and tell
Fun, if a bit disorientating, cheers :)
I love this stuff, Takes me back to my career as a teacher, god i miss it, exellent, !
We had to put 2 gps at each corner of an tc losi and this could calculate the drift and then the MSc students would scale it and run a simulation, was a brilliant project!
I love the idea of teaching things through practical experimentation - so much better than the plain theory
@@CurryKitten yep, i miss that career, i couldnt wait to get to work some days!
