- Onboard REALTIME Telemetry Cockpit Display | DJI FPV RC Freewing Avanti EDF JET | FIRST FLIGHT !
2nd improved flight here: • AWESOME FPV FLIGHT | O...
We have been a long time fan of the Freewing 80mm EDF Avanti as an aerobatic sport jet and it was about time we converted it to head tracked DJI FPV. We have designed our own smooth moving pan/tilt mechanism with a bearing and two servos that moves as the pilot on the ground moves his head. We use the FatShark External Head Tracker module but are also close to having our own 'Essential RC' head tracker. The flight footage is from 2 flights one of which was flying with Jason 8S powered Avanti which was difficult to keep up with. In future we'll have the same setup so can fly closer !
In this video we also tested out the RCGauges realtime telemetry display. It is available in either standalone or iNav versions. We purchased and tried out the standalone 2 inch version. Although functionally it works very well it is not viewable in the bright sunny conditions when we flew, much like any other LED display. We'll be using this LED display again when its not so bright on cloudy days or in the late afternoon. We will also try it in other projects especially in cockpits that can provide a lot more shade. Look on www.RCGauges.com for more information.
Note that to reduce the unfortunate flicker effect with the DJI FPV camera a Caddx 14MM ND8 filter should be used. This happens because of the mismatch in frame rate/frequency between the camera (60 fps) and the OLED (90 hertz). An ND filter on the camera forces the automatic shutter speed to be longer duration and this prevents most of the flickering. For the DJI FPV camera to have best focus the LED display needs to be 10cm to 12cm away. Ensure this can be accommodated in your cockpit layout. If not, then consider the smaller LED display sold by RCGauges.COM

What brand or model ND filter did you use with this?
@@MatthewTaylor3 Caddx
Paint the foam black, so the camera adjusts its shutter speed to allow less flickering from the screen. And you can also use a dark canopy as an ND filter.
Aha. Maybe just paint the foam around the display? OK. Will do that. Thanks for the advice.
@@EssentialRC The reflection of the sun makes the camera use a high shutter speed causing that undesirable effect from the screen.
Yes. I do realise that hence the ND filter.
@@EssentialRC seems like the filter didn't do much at all.. maybe cutting back the MHZ to match might be better... just my thoughts.. higher rez lower mhz..
A real working cockpit display! Woah!
I need this FPV in my life lol. I was interested in this hobby. But now, I am really interested in it.
That is SO AMAZING.
Brilliant.
Wow, respect. So cool 😮🤩
Ha! That's awesome, man!!
That is mental bonkers ! Bloody awesome
That was first flight and display wasn't that visible. This was much better. czcams.com/video/uaSn3-eYFTU/video.html
Awesome awesome video!
That is cool!
It’s so excellent more and more companies are making FPV displays now
Tooo cool, well done!
That was an early first attempt. Much better on this subsequent flight... czcams.com/video/uaSn3-eYFTU/video.html
Amazing!
Thanks!
Vanta Black is great for use inside of a cockpit with a headtracking camera. Great video 😃👍
That's a perfect setup!
Along with the end filter and black matte finish of the dashboard, I would suggest using a e-paper screen! You'll not get all the colors (you'll find tri-colors versions), but at sunlight it's perfect vision, no glare, and much less power consumption!
Thanks a lot for making me discovering rcgauges!
I suspect the guy at RC Gauges looked into that. Not sure there is a version small enough or programmable like this small OLEDs. I'm just a customer of RC Gauges demonstrating what I brought. I rely more on traditional FPV OSD now for my flying. These displays look good from a cosmetic point of view but aren't really good enough to help a pilot when he is flying.
Cool glasses!!! I realy love the decal!
This is insane.
Exiting to see how RC flight has evolved. We made a lot of noise in the 80’s. Nice flight and super idea with the instrument panel. Problems with it will get solved. Nice goggles too, perhaps try a holographic sticker on it so you can blink an eye?
amazing
impressive
Keep going !
That's the plan!
ESTA GENIAL EXELENTE , UN SOLO INCONVENIENTE , NO SE VE A LA LUZ DEL DIA
This is great Dom. I've been inspired by your projects and have an FPV EDF project underway. Going down the Inav path to get a good OSD integrated into the FPV view, but also means a lot more testing of the flight controller before taking to the skies.
It does but it's a must to be honest. So many advantages to it especially return to home, autopilot etc on top of the normal telemetry. Very important especially to cover the scenarios where you get lost or lose video or control signal. I've got a couple of Matek 765s that I'll be using on future projects. Will do a video on that soon.
@@EssentialRC Treasure them as I dont think matek is thr 765 any more due to parts availability :(
I heard that. No doubt there will be an alternative in the near future.
nice
Was great Dom, agree you should paint the rest of the canopy interior black. Brilliant flight thou and landing 👍🏻
Thanks! Yup. Will give that a go.
gave it a thumbs UP just based on the EYES looking through the goggles.
Since most of these cameras use shutter speed and gain instead of an Iris, perhaps a +9 neutral density filter would slow the shutter down enough to make out the AHRS screen. It's an easy test. Very interesting video! A micro version of what I want in my full-size aircraft!
You did watch the video?! I used an ND8 filter.
@@EssentialRC each ND step is cutting the light passing through in half. so a nd9 is much darker than a 8
David Windestal did a really cool cockpit that the hand was moved by the stick which was visible through the FPV.
I wanted to inquire if the improved version of this telemeter screen is available also I wanna know if you can custome made it based on request. thanks
I have tried this with a small android phone on board (there are many apps like efis ta) with DJI air system. Visibility of display was better than this, however sunlight was a challenge though (I had to cover the phone at all the edges with some success). The other challenge is the magnetic field that the brushless motor produced which cause erratic motions at the display). I tried some magnetic area covers which are so expensive and heavy. The better solution would be the using pusher motor plane to put more distance between the phone and the motor. Anyway, small andorid phones could be used to get an onboard display in fpv planes (of course even with the ideal conditions and settings the readings would not be so precise for the altitude and speed as it is gps based). Anyway, real time display with digital fpv for sure will make the hobby much more excited and safer…
I've been wanting to do this. Tried it in my fpv extra but with a plain OLED. It was lame, esp bc no data displays once armed. I have to get one of these
Outstanding, very difficult to land in FPV mode. Congratulations!!
Yes it was!
Looks like the instrument panel was a fail, at least in this video. I could never see it. I would think all you need is airspeed and maybe AOA indexer lights. Another thing might be a gauge with a needle that always points out relative bearing back to base. It would need a pitot tube for airspeed sensing and an AOA sensor vane. The bearing back to base could be via GPS. With airspeed and AOA indexer, you will be at the correct airspeed for landing and maybe can fly a stabilized approach.
This is absolutely insane and awesome! Are there any military fighter rc style that are electric fast and that I could outfit with this and head tracking fpv?? I want one so bad...
Where to buy this? Is it possible to adjust the barometric during flight in different location in case of long distance flight?
Real planes with glass cockpit have the same problem with brightness and contrast, the solution is to put a foil around the digital display, so that it casts a shadow over the image most of the time. By the way, tell your friend that the Artificial Horizon usually goes on the right side of the speedometer, seen from the pilot's eyes. Congratulations, excellent job!!
We solved some of the problem by using an ND filter on the camera to slow the automatic shutter speed. czcams.com/video/uaSn3-eYFTU/video.html
Hi, is the pan/tilt unit available for sale anywhere?
Freaking Koool viewer!!
Caramba!
I live the goggles, better than the Vision Pro ;-) These eyes look like the real ones :-)
does that website for the gauges even exist? can't find it
hi, this can be future low cost flight simulation for cadets in flight school =D
I 3d printed this same setup awhile back haven't used it yet
Great concept technology for RC jets. It was fun from RC pilot point of view, but could not see the monitor, unfortunately, would have been great. Understand it’s in the infant stages. Hope better future.
This was first attempt. It was better after we used an ND filter on the camera to slow the automatic shutter speed. czcams.com/video/uaSn3-eYFTU/video.html
is it possible to use bigger monitor with it??? and is there any higher quality improvement for this???? this is exactly what I need similar to a GA aircraft instruments. how much is this by the way?
Read the video description
Nice, where buying the complete telemetry system?
try painting the surfaces between the camera and screen. It will reduce the reflected glare and increase shutter times without the dimming effect of the filter.
This is pretty inspiring footage. Can anyone tell me what a setup like this (FPV plus RC plus plane) would cost to put together?
FPV goggles/camera (i.e. DJI but could go cheaper analog) £800
RC jet + batteries + receiver £700
RC Gauges display £250
Transmitter £100+
@@EssentialRC thanks mate!
Maybe look into e-paper displays? Or non-emissive LCD, like old Tetris machines
👍
You need the area in front to be black, and also a partial cover over the screen so it doesn't get washed out from the light
Tried that and it didn't help much Fred. Was improved by adding an ND filter on the camera to force slower shutter speed. This is a later video with better result but its still not readable enough to help the pilot. I rely on FPV OSD now. czcams.com/video/uaSn3-eYFTU/video.html
Is it visible at all during FPV because you can't see anything on the recording?
On that first flight not that good. I had to add an ND filter to the camera and it was better for the 2nd flight but still not that great. czcams.com/video/uaSn3-eYFTU/video.html
Would like to know your cpl setup, also antenas on DJI goggles!
Hi everyone,
could You please give me the right link where I can buy these display ?
I desire to placed on my Duo Discus scale 1:3
Thanks a lot for everyone anserw me
Ciao Matteo
It's in the video description!? 🙄
Great flight ! But it seems like the instrument panel is unreadable. It blinks a lot. Could you read the panel? Qustion II: In the panel, do you have more room for a map, or compass that will show you the direction for the take off point?
As I said in the video the display is not viewable in direct bright sunlight. Would be true of any other OLED. I will show soon it being used on a less sunny day and the results will be a lot better.
The problem I referred to was not the brightness but the blinking. Does it blink in your headset? And second question is can a compass that will show you the direction to the "air-port" can be installed ?
@@dorond6088 Even with the added ND8 filter it still blinks a little but it is better with less sunlight. The compass on the display shows the direction back to home. No need to install anything else. The 'standalone' version of the display comes with a compass.
Thanks. I'm dreaming of doing this with helicopter like the MD500 (Where the feet are "hanging outside"......).
Maybe fire a rocket or two.....
Where can I get that gauges display ?
Details in the video description
@@EssentialRC literally the second after I posted this comment I went to the description and found it but forgot to delete the comment. Thanks!!! Keep up the amazing videos!!!!
where U got the Hud panel?, Is really cool!!!
Link is in the video description
You need the canopy or it’s not cool
What I would do is make a realy, realy long black mat, rectangular hood around this monitor, so no day light can easily reach the monitor. It will be like the way all aircraft cockpits are inside; dark. I see you've made this round black shade, which looks realy good. I would keep that round shade & also install the rectangular hood also, & see what happens.
Tried various options and none really helped other than using a Caddx ND filter on the DJI camera to force reduction of its shutter speed and flying on a cloudy day. The latency of the data being displayed is quite slow as well. It's not really good enough to help me as a pilot. I now use Matek flight controllers so I get fast accurate telemetry in the OSD in the goggles. Hoping soon that it will be customisable and recordable.
Hi how to buy this, where ?
Hi all realy nice smaller hub, for the vison on board try to color cockpit in dark, but don't leave it white, to much white reflex !
analogic instrument to mesure Light "exposimeter" tell you how the best light to see display, at home it's differnt to sunshine, and litte black par-reflex to avoid direct light on the screen
...And in the next episode I will demonstrate an ejection seat for the camera...
Exciting setup. Did you ever consider putting the display back in a black box? Think of an unfolding laptop hood for outdoor use. Stoping direct sunlight and leaving only indirect sunlight would improve it. And since the pilot's "eye" is in a known position it should see through the box quite well. I am also wondering if you made a front 1/2 canopy out of curved card stock, perhaps everything inside the painted flat black if you wouldn't be able to see the screen. You'd be shading everything you can't see through anyway and the screen would be the brightest thing in that background.
Experimented with a hood but the bigger I made it the more it reduced the view. Adding an ND8 filter to the camera helped a lot. This was a later flight with that setup. czcams.com/video/uaSn3-eYFTU/video.html
@@EssentialRC In the view, the cockpit totally frames your display. If the hood were carefully shaped to only take up this visual space (not outside the edges of the foam in the view) you'd still have a straight shot at the camera. You had a little hood in the last shot and the screen view though still unusable was much better. I'll go watch your link now. Thank you for the response. Liked your video.
I have a display on order fro Gui! It’s been stuck in customs in Chicago for two weeks. I can’t wait to get it! Can you share where I can get the head tracking camera gimble set up you mentioned was available on eBay?
Link in the video description
No longer available there🫤
You should have a black shroud around screen reaching all the way to the camera lens so that no ambient light reaches the screen. Obviously don't cover the entire camera with the shroud but as much as needed to display the screen clearly
Great but then I wouldn't be able to see anything else. Problem partially resolved with an ND8 filter. It looks better in this video. czcams.com/video/uaSn3-eYFTU/video.html
An eink display would be perfect
It would maybe be better to have the screen information appear on the video feed instead of sending it to the screen. Have it like a helmet mounted HUD. The lack of exposure controls means you're never really gonna get it to appear in day light.
Agree. We call that OSD. More recent projects use that as the data is displayed almost instantly and is very clear.
I thought that too. That’s exactly what drones in the army have.
I was just talking about doing something like this to my Habu!
firstly place non relfective black tape over the white areas nearest the display to reduse sun relfection and light glare... the second pivot to the camera should be redesigned or camera moved forward to reduce pan tilt issues as well as allow it to be mounted inside an encoled cockpit and running two drinking straws as air inlets heated to bend and aimed at the top of the camera controller and a venturi type exhaust port cut onto the foam will provide ample cooling I would love to test this product and help evaluate a Version 2 I can also provide my updated camera mounting STL file so you can print and test out yourself included is also an STL with cooling ducts that can be placed into the foam body to provide cooling to the cockpit area and a venturi type exhaust port that can also be mounted to the body of the fuselage to use vacuum to expel hot air from the internals.
I've learned as long as your inlets are smaller than your outlets AND/or the outlets are located in an area of lower pressure (most areas of drag or air layer separation) air will be sucked into the inlet and out the exhaust port. Respond and I will send my designs. I wish they had a way or sharing photos in comments lol.
Nicely done! Does it has any purpose?
It's cosmetic really. The telemetry does not get updated quickly enough and isn't clear enough for it to be useful to a pilot flying FPV. Better to use a proper FPV OSD system.
the first Thing i do,is on the next Fly to check if there is a real Pilot or only a Cam and the Pilot sit at Home and drink some Win and fly with FPV all to Hollyday.
Full tutoril for ...head tracker set up😄
A visor / shield over the top and sides of the screen would help the visibility a lot.
Tried it and it didn't actually.
Given that the frame rate difference is the only major issue with the screen, it would interesting if the screen's frame rate could be adjusted to suit different FPV camera setups.
RCGauges said it can't and that limitation is typical of those types of screens
@@EssentialRC That's too bad, perhaps a company or someone in the community will find a workable alternative. Never know, could be sooner rather than later :D
You put a flashing light beacon on the field.
7:28 Glare Shield like real aircraft?
Please do it again, can't see
What's the point of a telemetry cockpit display, if you can't read it due to the sun light?
It was disappointing in this video. I did improve it a lot by using a Caddx ND filter on the camera but still not to the point where I would rely on it. This was a while ago. I use DJI OSD now. There's a hope we'll be able to customise that in the future to be a more realistic HUD. The cockpit display was a little laggy anyway. OSD telemetry is almost instant.
czcams.com/video/uaSn3-eYFTU/video.html
dont you have this info in your headset?
Yes but this is more scale and was fun to try.
What is the range of these planes? Flying time as well as how far away they can be from the flyer?
The limitation is visual range.
@@EssentialRC so the remote system has a very long range? As well as the FPV?
@@corvetteZ3r Depends on the system used but can be up to 10km apparently. In UK by law we have to stay within visual range though.
@@EssentialRC oh okay. Not sure of the law in the US. I really want to get into the hobby it would be super cool to fly over friends houses!
So many reasons for that being a bad idea 😆
How can i buy this little Display?
rcgauges.com
Is that a real airspeed indicator
No. GPS ground speed
A small sun shade for the display
No. That would block rest of view. ND filter added to camera for this flight czcams.com/video/uaSn3-eYFTU/video.html

Link for the gauges?
www.rcgauges.com
..I meant to say paint the surfaces matt black.
We did. It didn't help much. It was mostly improved by using a Caddx 14MM ND8 filter. czcams.com/video/uaSn3-eYFTU/video.html
It needs a shroud. Nice set up though.
Haha that goggle decal is so creepy.
Just put a shroud around it
If you built a little hood over it you could see it maybe better
Tried that and it didn't unfortunately. It will be better in a closed cockpit or in less sunny conditions.
Mhh... The potential _is_ there but man does it _not_ live up to it... I skipped through parts of the video and may have skipped over it but why can't the Screen be set to a lower 60Hz if 90Hz is its upper limit? I imagine the DJI Camera having a 60Hz upper limit with downward adjustability would mean it doing like 15-30-60Hz? If the Screen were to run at a _constant_ 60Hz then even with the Camera switching between modes should have it run at a synchronous multiple of 15Hz whereas with 90Hz it'll only ever run synchronous at 1/3 of the time. I mean... The obvious choice though would be the use of an OLED Screen that doesn't have a TFT like refresh rate.
Also maybe consider adding a considerably far into the cockpit extending canopy over the screen to create a shadow box around it?
If done properly it shouldn't impede vision with the camera but _may_ help with visibility... I mean... Cockpits in real fighter jets have them soo... yea? 🤔
Something else that is bothering me is the location of the Tilt Axis on for the FPV Camera... Why is it so far off the camera housing near the base of the Pan Axis? Wouldn't you want it to be more in line with the housing of the Camera and thus more closely resembling the motion of a _Head_ tilting up and down instead of going full Giraffe lowering not only the Head but _also_ the Neck and all? 🤨
You're right but it was first attempt. The camera shutter speed is automatic so we forced it to be slower by using an ND filter. I experimented with a hood but it didn't help much when travelling away from the sun on a cloudless day. Regarding the pan/tilt...I didn't design it but it works well enough. I rely more on OSD telemetry in the FPV goggles now. Faster refresh and lower latency. Here's a later attempt with the OLED display. czcams.com/video/uaSn3-eYFTU/video.html
Can’t see anything due to light
Improvement on this subsequent flight when we added ND filter to the camera lens czcams.com/video/uaSn3-eYFTU/video.html
How about integrating the display as a head up display instead. That thing is useless. You cannot see anything on the display if it’s too bright.
paint interior in black not white , here dont work
Damn, can’t see jack.
Yup. Difference in shutter speeds was the main problem. Better in later videos but not perfect
kkkkkkkkkkkkkkkkkkk BLACK SCREEN
Wa is cji
Change the frame rate on the camera 😉
I think you mean shutter speed. We added an ND filter to force it to be slower as it is automatically controlled by the camera. Improvement after that. czcams.com/video/uaSn3-eYFTU/video.html
@@EssentialRC an ND filter will make it worse. What fpv camera are you using? Are you recording on the goggles?
Дисплей только мешает. Все что надо и так есть.Я не увидел ни одной информации на дисплее. Черное пятно.
