  • steveo9007: Cheers Atom was just a thought for now as I plan on keeping it well in range until I get comfortable with controls and flying

  • atomiclama: steveo You can just plug a GPS puck into the FC and get the OSB to display the coords, record the VTX and when things go tits up you have the last known posistion. Whislt not accurate it is a good starting point. Or get the coords sent back by telemetry to you TX which will be more accurate as long as power is maintained to the quad and it is range with the TX. Just some thoughts.

  • steveo9007: Is there a post on here about the 433mhz telem tx ??

  • steveo9007: ok thanks shaw
    December 03, 2018, 20:31:44
  • shawdreamer: meanwhile the 433mhz telem option I mentioned gives you live fixes in realtime and not "delayed texts"..... plus it doesnt cost you credit everytime you request a gps fix (btw the tags sim card also needs to have credit on it :laugh:)
    December 02, 2018, 20:47:10
  • shawdreamer: and yes that does actually work..... I tried it for a laugh a couple of years ago ::)
    December 02, 2018, 20:45:09
  • shawdreamer: the tags do as you say use satellites to get positional fixes but they dont immediately report those fixes to an App, each tag requires a Sim card (same as your phone) which is used to "text" you the tags position..... in other words you could get the exact same effect by strapping a old smartphone to your frame with the google "where is my device" app installed
    December 02, 2018, 20:44:13
  • steveo9007: doesnt the tag communicate with the satellites and not via a data system, isn't it the user who owns the tag go via data to the app that can locate the tag ???

  • shawdreamer: plus, alot of the lower end trackers struggle with GPRS and often rely heavily on GSM data instead which is just not worth a sh1te when it comes to pinpointing a downed frame
    December 02, 2018, 16:23:30
  • shawdreamer: most readily available gps trackers are not really suitable for anything smaller than a 400 sized frame as the units themselves are often too bulky for anything smaller and larger frames often already have their own gps setups that can simply be outfitted with a 433mhz telem tx that would report live and accurate info direct to a ground station so there'd be no point in a sms type tracker

  • steveo9007: anybody fitted a GPS tracker tag to their drones if it gets lost and is need to find it

Mysteriously Bent Zenmuse H3-3D
« on: September 25, 2018, 08:37:00 »
I have a Zenmuse H3-3D (attached to a Phantom 2). I crashed it (into soft ground) a few months ago and Im pretty sure that the Zenmuse H3-3D gimbal is slightly bent. It's not clear how it's bent, but it would be clear if I could side-by-side a known good gimbal.
Unfortunately I don't have a known good gimbal, and nobody in my area does either.

I wonder if any drone engineers (dronegineers?) reading this might offer to repair (unbend) my gimbal for me? I understand that these gimbals are quite tough and respond fairly well to bending-out.

not expecting a free repair - will pay a reasonable rate.

This gimbal still works quite well, but when the camera carriage is swung in the Roll axis, it does not freely clear the upperworks of the gimbal. There is not enough clearance between the top of the camera-carriage and the bottom of the mounting plate.

I have closely compared my bent gimbal to various pics & videos but it's still not clear!! I am sure it would be obvious when compared with a good one though.

Welcome to the forum ~~

Are you able to post any pics to show exactly what the problem is?

Looks like the arm coming from the back round to the side is twisted therefore raising the side motor and causing your clashing issue.

Obviously I could be wrong but that's certainly what it looks like in the vid.

You could potentially twist it back but I believe it is made of aluminum on that gimbal so it may break off if its stress fractured already.
Personally, I would want to replace the arm but I'm not sure if that can purchased separately.

that is what I thought. it is not "noticably" twisted however.... As I say, it really needs to be side-by-side with a known good one to see what has bent I think.
Dave or John at Marionville (where I bought it from) said to just unbend it, he has unbent a few and they are pretty robust. I tend to agree and I certainly would have a go if I could be certain which bit was bent!

I would pay anyone that felt more confident than me to side-by-side it with a good H3-3D and then have a shot themselves.....

anyone?... anyone?

I'd say it is very noticeable! :smiley:
<br /><br /><br /><br />

I would love to be able to help you but I would not be confident it wouldn't break :(

It looks like it's cracked!

not cracked, at least not there - that is the edge of a ribbon cable.
SHould the suspension pin on this mounting interfere with the pan motion at one end? the instructions advise pinning only 2 of the 4 suspension rubbers, on the diagonal, which makes some kind of sense, but should it foul the gimbal?
