He's back!

Glad to hear someone else is experiencing the same issue. Mine jitters like crazy too. Thought it was just my setup..

You could totally fashion a little rear view mirror for that thing lol.

Nice work!

CADDX FPV just recently release their GM3 (and their GM1 & 2 axis as well) gimbal system that seems pretty much the same beside only for Walksnail system. Both systems looks pretty decent.

Great work Chad, been lookijg forward to this review mate👍🏼 Keep us posted with any developments, this looks like a promising product if they actually do care enough to support it👍🏼

Excellent work Chadd! It can be very difficult to get gimbals running 100% smooth for sure. Still learning myself after a few years of messing with the storm32 diy units. The mounting to the rc is as critical as anything else especially running high speed and off road. I've had the best results from bolting the gimbal to the chassis. Really, a riser from the chassis that's bolted to the chassis if that makes sense. If you feed some steering into the yaw it'll force the gimbal to look into the turn and still stabilize in yaw, but like you say yaw can be locked out. Most of my fast cars I only run pitch and roll. You could try mechanically locking the yaw axis just use a bit of tape and it might help with the left right shudder your having 👍🙌

Thanks Jipperr! HEQ replied and said they are working hard to fix the issue. I’ll try to lock the yaw and then mechanically fix it as well. Hopefully this doesn’t burn up the motor (not gonna lie I’m a bit worried about doing that). Will follow up! 🤙

lol using tape is exactly what I did after panning the whole thing with a separate servo. I realized that it does work but then you're not letting the gimbal get rid of any micro yaw jitters.. The truck I put it on is real stiff so it does a lot of that bouncing side to side that comes through in the camera quite a bit. So it seems like the only actual solution is a good 3-axis gimbal that allows you to trim the Yaw axis compensation limits without actually locking it out altogether. Or like you said, mixing the turn direction in with the Yaw which is a great idea.

That’s pretty sick. Might actually make me finish an fpv car build😎

FPV Cars are getting good these days!!

So you DID get the fireteam, nice! I'm glad another person aside from Jipper is on the gimbal stuff. There are still too many concerns I have before trying that out but it does look amazing all things considered. Is there any way you can see to simply disable the jitter axis? I would love to have it all setup so I could still look left/right up/down but I guess I would only need up/down stabilization for off road.

Hell yeah dude the Fireteam is awesome😎 I need a custom body (or plate) but that will come. I did use the “FPV Mode” that locks out the yaw axis (the jittery one) but it didn’t lock it well enough and the jitters are getting through. I’ll be sending some more info to HEQ to try to get this resolved, and hopefully change the name of this video (dropping the “Almost” lol)

@@ChaddRainsFPV Man I've been debating on the Fireteam for a while now.. It's like I already have 2 others a bit smaller but I want my third one to be a complete monster. Like big enough for me to put a dang articulating airsoft gun on it or something. That's a huge endeavor though so in the mean time something like the Fireteam would be awesome.. The main thing is though I wanted to be able to mount the O3 inside the body so it's a true FPV experience. Plus the roll cage for hard driving etc.. Haven't yet figured out a way to make that possible while also using a gimbal. Needs just the right dimensions on a truck... OR just need to butcher something and mod it out real hard. The way you have it mounted on top seems fine, it just sucks thinking about that amount of work put in if it crashes hard one day. The mounting on top also has that benefit of perspective though.. Just makes it so you can actually see beyond obstructions that are only several inches high. Complete custom body where the cam can sit high and it still looks like you're inside a cabin might be the best bet.

Really good review. Just got my hands on one of these and I don't have any jitter with new firmware but my yaw struggles with staying centered. It's always a bit off for some reason. Apart from that it's a great wee gimbal.

@ChaddRainsFPV I have ancient Hong Nor x2 Pro buggy with Hobbywing 6s 150A esc, speed wise can't say as I haven't measured it but probably around 50mph. Weirdly the drift is only present on new firmware with fpv mode on but old firmware has jitters. I guess drift can be fixed with another firmware update if they do release it.

@@BeyondGravityFPV Correct me if I'm wrong but I'm trying to figure this out. So basically it seems like when not locking the Yaw axis, it's relatively smooth and everything seems fine except for in certain situations when you get major twitches. However in FPV mode locking the yaw, you get the drift from home and it does the buggy twitch thing a lot more right? But this buggy twitch still does exist no matter what?

@@Magneticitist Let me try to clarify this a bit, stock firmware vibrations on pitch and twitches on yaw. Fpv firmware only yaw has twitch. Both fimwares try to follow centre on yaw, there is no way to really lock yaw, it aways moves to some degree. On fpv its more limited to how much it travels but it still moves (not to mention it has like 5 degree fee movement both directions so it struggles to centre). In general i have tested this gimbal for several days recently and few times it tottaly lost level, like gyro didnt know what was happening. Strange and it definately needs tweaks from firmware side. Also it would be great to have more options like how much power goes to motors speed of the movement in angle mode etc.

There is only 3 signal wires from the gimbal, and one is a black ground wire. There is only one “4 wire harness” with red, black, green and yellow. The ez start manual shows where to plug this in at 🤙

Hey do know if this thing would work for me using Crossfire? I use mainly 8ch diversity receivers with the PWM adapters but on the controller I've got the Crossfire Lite module using the DSC port and PPM. I already bought it but now I have to figure out if I need to change my controls up to use it. Also, where can I buy one of your arming circuits?

@ChaddRainsFPV

9 күн бұрын

Shoot me an email and I’ll make sure you get one. But yup you have a couple options with crossfire. Technically, you can use the 8ch PWM adapter, and the gimbal can use 3 of those channels directly off of your receiver, just like that. But you can also take set crossfire receivers to output sbus, and some other converters do Sbus to PWM. You can actually tap right off the Sbus line and the gimbal has a port for that. So if you needed 8 channels on your rig, plus the gimbal, you can do that (11 channels, basically). Hope that made sense brother, typing this out while partying with the fam hahah 🤙

@@ChaddRainsFPV So I got this thing earlier and just finished setting it up and I gotta say I'm pretty happy about it. I drove it around the living room a little and was surprised how stable it is..The calibration process was a little iffy but it managed to basically look where I wanted it and allow me the movement control. I guess I can't complain that there might be some jitter issues considering how easy of a setup process they made. Sucks that it's dark already cause I have to wait til tomorrow go to try it out in the woods. IDK exactly how they want to lock the YAW but I just upgraded the firmware. How did you go about calibrating? I already had it all mounted so I sort of just awkwardly tiled the truck around, having to sometimes manually move the yaw by hand to get it to look a certain way for the calibration. Just sort of held a consistent straight forward direction on it for that calibration hoping it would make it a centered home. Only problem I've seen so far is it wanted to very slowly drift by tiny amounts to the left when I have it just sitting there. It's easy enough to hit a 'Home' button to bring it back any time I want but IDK what causes it. In that regard I suppose one easy fix via EdgeTX (if it allows it) would be to mix in that Home channel being pressed basically any time the steering or throttle channel is used and just get used to only looking left or right when stationary. Anyway I got it all trimmed and running like I had my rig before but just with this badass looking gimbal and I can't believe how easy it was.

Hi brother. I have already emailed you but not sure if its in your junk box. Kindly check when you can. I am posting what i found here so others can learn as well. I am going to be buying these products today so please guide me.

Also, i would like to buy the armer from you to arm the dji air unit. My question is do I still need to assemble if I buy the walksnail unit? I will be putting these on a traxxas xrt or buy a smaller rc like sledge or something. Thanks brother for any help you can give.

I just shipped all the units from our last batch, so I’ll be responding to emails in the next couple days. Thank you for being patient! I prefer the O3 and DJI Goggles 2 or Integras. But they are only compatible with each other. You can’t use Walksnail with DJI, and vice versa. I will be testing the Walksnail GT to see how it is as soon as I can!

Thanks for sending this over! The fix for the Caddx gimbal doesn’t perfectly translate to the HEQ, but I’m sure there is something to be learned by both companies from this fix. They are both trying to lock the yaw axis, and resulting in jitter. It looks like Caddx has a work-around (that kind of limits the use of the gimbal and requires some fancy configuration to be done, as per BonafidePirates video). I think both companies could implement this in the their app, so you could toggle this as a setting and not require any input to the gimbal or special configuration from an FC. That is my hope, anyway!
