Medlin FPV Gimbal on iNav 7 // HOW-TO

[@jamescunningham541]

Of course 😂 because I finished mine today. Jb, your servo tab vid helped out huge. Now got channel forwarding working and taking a first flight tomorrow!

[@VadimBryksin]

to avoid servo skipping because the move is too long you can limit it in inav to some 70% of the servo movement, dont know exact number of percentage, but you just reduce the default 100 in the inav servo mixer to something lower

[@Mrcovert]

Back when the ZMR was the drone to fly we had a server tilt camera on it with a 3D printed mount and controlled by a servo output that would keep the camera level as the drone flew. Never connected it to head tracking like this tho.

[@MCsCreations]

Pretty interesting indeed! Thanks for the tutorial, Joshua! 😃 I've never thought I'd see a servo gimbal that smooth! Anyway, stay safe there with your family! 🖖😊

[@KanaBaradei]

JB there is an additional thing you can do with INAV while using a tilt camera. Instead of setting the servo to an RC channel, you can set it to the tilt gimbal function, that way it would behave as a stabilized gimbal (only in pitch ofc). Additionally, you can set the CAMSTAB function into the modes tab to select when the camera will automatically adjust the tilt. I'm guessing that if you combine all that with rocksteady, you can reach something close to an avata. I've been wondering how well this would work, could you perhaps make a quick video on it to show to the ppl? Thanks for the work you do for the community!

[@divingfalconfpv4602]

Use position hold mode to fly with cam stab

[@KanaBaradei]

@@divingfalconfpv4602 Yeah that was the idea, but i'm more concerned about the servo smoothness. Tried to search videos of ppl doing it but literally noone has

[@mxracingunlimitedltd7784]

@@KanaBaradei I mean it looks like the servo kit can do whatever you need, just need to make sure INAV keeps it centered to the Horizon first so it goes to center position..? It seems to be able to move plenty fast enough..

Hahaha… I’ve owned a couple of Audi and BMW and that working on a German car was bang on. 😂😂👏👌

[@koki.k]

Back in the days we had 3 wires for the fpv camera, and you could just cut them and make them longer :)

[@DaRoach588]

Interestingly the HDZerp Eco has gone back to 3 wire like analog... I'm excited to see if that continues in the future

[@tysk5729]

Ive thougt of this allot, and i think its a pretty big deal not underwelming at al I mainly fly in simulator, and being able to switch between a big angle and a small angle for slow flying and hovering would mean a ton off difference Being able to controll this with your head seems perfect, as controlling it with switches seemed to suck

[@defyent]

lol, i made this same concept 7 years ago. Different tilt design but same concept. It was more about having a variable camera tilt angle for racing. It worked okay. Cool concept to use it for filming.

[@swissfreek]

13:43 Ahhhh, bringing back my nightmares! First car was a '94 VW Golf. Literal step 1 of changing the oil filter: "Remove front clip." 🤬

[@justinmuller4809]

thats cool! but i'ld adjust servo endpoints : ) you are right about german cars lol.. escpecially the multi link axles from audi / vw pain in the ass, but they drive beautiful

[@JPspinFPV]

It's a pretty chunky tilt gimbal, but I get it. I ran into the same problem with the mipi cable and ended up just going with analogue. So much easier.

[@schweizerluchs7146]

Bigger servos are more precise, so I can understand the decision, oh, and for sure to support the weight of the GoPro.

[@JoshuaBardwell]

It's to support also the weight of the GoPro.

[@spylife8650]

​@@JoshuaBardwell I know this isn't about this video but wasn't shore how else to ask a question. I am new to flying drones. I have your 5" beginner build drone from like 4yrs ago when I am hovering and I give it 1/2 stick yaw it freaks out and climes like crazy for about 20 feet. Can you give me some pointers on where to start to tune this out?

[@OnPointDroneWorks]

Got one on my bench just need to make time to finish the build. Thanks for the video I will commit to making this happen soon.

[@PerseidArchimedes]

[@blackwater7183]

I've always tried to figure out how DJI does it with their FPV drone. They use a slim type (pancake/gimbal) motor that has a magnetic sensor and probably has a dedicated module to control it. There are only a few manufacturers who sell gimbals but it's servo based and for fixed wings.

[@jpslaym0936]

This drone gets lot of grief but it can capture subjects like action in a more professional looking way plus 4k video with no gopro and can fly 85 mph / 15 mile range rather than 50 mph max like Avata 2

[@GiantAntCowboy]

@@jpslaym0936 Yea, I was “late to the game” and just recently got a couple used DJI Drones for my family & friends to play with, but I actually love them for various reasons. (Posted a video about it) Of course I lost one of them in the first week during a mountain surfing test… lol!

[@techstuff6829]

Camera drones and cinelifters use brushless gimbals as opposed to servos, which as you say requires a separate control module. Check out the SIYI A2 for a single-axis brushless gimbal camera, or the SIYI A8 for a three-axis brushless gimbal camera.

[@Rothammel1]

pls check out the packet rate: 64 / 128-pos: The bit depth is dependent on the selected telemetry ratio. For a telemetry ratio of 1:2 and 1:4 these channels are 6-bit/64 pos. For all other ratios, these channels are 7-bit/128 pos. The 7-bit/128 positions is 12.5% the resolution of 10-bit, and 6-bit/64 positions is 6.25% the resolution of 10-bit. This may not be enough resolution for a head tracker but definitely enough for flight modes, flaps, gear, etc.

[@jpslaym0936]

This is the one thing the DJI fpv potato can do that makes it useful for capturing action sports. Still a drone that distentegrates when it touches anything tho

[@ElementalGeneral]

Nice Camera Butter shirt!👌

[@techstuff6829]

Joshua, I assume you'd want to mix in a "GIMBAL PITCH" input along with the camera pitch override from the TX so that by default if you hold your head still the camera angle will stay fixed regardless of how the quad pitches, but if you tilt your head up and down it will "add" that to the stabilized pitch input to let you look up and down? Could even put CAMSTAB on a switch to enable the stabilization in flight?

[@carcomp101]

Hey @bardwell... why hasn't anyone come up with a 180 degree camera "fish eye view" that has processing on the headset to generate the head tracking? We certainly have the processor power to do it, and it would be much more robust than servos. It would also be fast. You could theoretically move your head and have instant feedback like VR. I've suggested it many times and the only drawback would be "forcing less than HD by only taking a portion of the 180 degree image... less than HD" but that doesn't sound like a very solid argument.

[@JoshuaBardwell]

Sounds like a great idea. Why haven't you invented it yet? Hint: the answer to why you haven't done it is the same answer why nobody else has done it either. Ideas are cheap. Execution is difficult.

[@lievenvv]

Caddx + Insta360 collab coming up?

[@ddegn]

I think using a fish eye view type camera would require too many compromises to make it worth doing. I think you're much better off physically moving the camera. "the only drawback" Really, you think that's the only drawback? Fish eye lenses have all sorts of problems. The image quality would be horrible compared with normal action cameras.

[@BiswajitBag-ur2em]

[@MarcDunivan]

Try 3-axis rotation...radio controlled model planes and helicopters use these. Motion Sic has many dogfight videos on KZbin using a 2 axis gimbal.

[@unknownryan4675]

Josh , love the video. You mention wiring directly to FC. By pass 5v. I had this setup because my thought as well was if FC crashed servo last of my problems. I just had a spiral of death I could not recover now did rth help and hopefully will find but thinking now I wonder how much pull the servo puts on FC and at 100 ft plus and high demand build with weight if that's begging for trouble to crash the FC underload. Hopefully I find but my 2nd build with the medlin I'm tearing apart to put in the 5v reg off main power. Can't afford another loss. No blame game here and maybe I took your video wrong but if you ment what I thought you ment u might want to edit this video to highly ad ise to use the 5v and not direct connect to FC to avoid this risk.

[@nabilalhusail4731]

1. What about Jello? Is soft mounting an option? 2. What about 360 camera? It would resolve the same problem by setting the focus in post

[@maddercat]

this video is great, finally a guide on how to do servos...does this work with betaflight too?

[@arkdronesandlife]

The LDX-218 Servo has a stalled current of 2.4 to 3amps. The Matek 5v regulator has a continuous load current of 1.5 Amps (Max.2.5A 5s/minute). Should we be at all worried about that?

[@xxstopusxx7120]

Hello guys since this is by far the most educated and smartest FPV community I would love to get a little help from you. I have the DJI Goggles Integra and I‘m looking to get some more range out of it. Do I need to replace the antennas on the goggles and my quads (Geprc Darkstar20, Mark5, Moz7) or is it enough if I for example just replace one of the two and which would you recommend? Thanks for any advice or tips you may let me know of🙏

[@emilpers1078]

This reminds me of Motionsic, but they can both tilt and turn. Looks better imo. But dont know if it will fit a drone. They were more for FPV planes.

[@raypeery6317]

It's a nice piece of kit. Printing a mount for a quad would be trivial.

[@MamayFreeride]

I've already built something like this. But I just wasn’t smart enough to get the power through the battery. Well, I connected it to LED contacts. Which, in principle, is the same thing as a PWM motor connector. p.s. What's going on? You don't need to buy Avata 2!

[@SkeezyFPV]

[@GarengPetruk]

Thank you Uncle. I have followed, as in the video. where I soldered the line wire from the Runcham DVR's H/L pin to the M5 pin. and in the servo I selected it using the video that uncle made. but because I wanted to use the arming button together with the button to record video on the mini DVR, I selected the servo, namely the RC Chanel 5 input and it was detected. However, the current problem is that the H/L button cannot record fully. Oh yes, previously I used a Radiomaster Pocket Remote and I tried input 10, namely the Play button at the bottom right of the Pocket Radiomaster Remote, but the problem remained the same, namely it couldn't record. My DVR has a blue flashing light indicating it is recording but there is no recording in the video file. are there any other settings in the servo?

[@revodrvr]

Can I add a point on the osd to show u where normal flying position is of the camera. Like a home point

[@SimoneAragno]

That's crazy! For you it's possible to mount INAV and this Gimbal on a GEPRC Cinelog 35 V2? I read on the gimbal website that they've a versione compatible with the Geprc, but i have absolutely to use INAV? And so, i can install INAV too?

[@y_us_12]

Hi Joshua! Could you answer the question that bothers everyone for years. How to transmit live audio with digital video like O3 unit.

[@Johow]

I built something exactly like this in 2015. I bought the Attitude V2 since it was the latest Sh*t back then. I think I had a DJI Naza on a 450 flame wheel!😝😝😝 Anyone remember the frame? It worked okay but I constantly had to recenter the headtracker, since it was drifting. I would crash my 7inch if I used something like this today. How do you know what the drone is doing, while looking around???

That's why the avata is so awesome.

Hey Josh, great video as always. Isnt it possible to link to the a reverse pitch channel, this way you can maintain the object in screen regardless of the speed?

[@techstuff6829]

That would be a good starting point, but you'd want the head tracker on top of that.

[@sebastianuhl]

Is there a sim for that gimbal setup?

[@runpuppyfpv5744]

I don't think you got those gears back together right buddy ! I'm thinking of putting inav on my chimera now

[@PollokPoochesDogWalking]

im definitely going to crash alot with that upgrade!

[@MaxSMoke777]

I keep trying to point this out, and dumb people keep shouting me down, but if you put half of a 360 camera on the front of a quad, and just broadcast a small portion of view to the pilot, related to where the pilot is looking, you could effective make a FULL GIMBAL camera view without any moving parts. You don't need moving parts to make a full gimbal-style view. It can all be done with software and part of a 360 camera.

[@JoshuaBardwell]

Ok good go do it. The reason nobody has done it is not because it's a bad idea, but because it's hard to do. Ideas are cheap. Execution is everything. When you have a working prototype, let me know. Otherwise, stop acting like your brilliant idea is being ignored by the unwashed swine.

How about doing this on betaflight?

[@TomFYouTube]

For years, I never understood why quad pilots especially those of us that aren’t interested in freestyle don’t put the flight camera on a servo and a heading hold Gyro? That way, no matter how fast you’re going you’ll always be looking horizontally... It could of course be disabled with a switch on the TX.
