  • 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 ??
    December 04, 2018, 07:56:49
  • 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 ???
    December 02, 2018, 18:18:11
  • 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
    December 02, 2018, 16:22:07
  • steveo9007: anybody fitted a GPS tracker tag to their drones if it gets lost and is need to find it

Motors - hawksky 1107 6500kv
Props - gemfan 2.5x52
Cam -foxeer arrow micro
Rx - frsky XM+
Lipo - tested with 850mah 3s, probably try 650mah, see if flight time is too short

Running butterflight latest rc. 8khz/4khz dshot600

<br /><br /><br /><br /><br />i want to delete<br />
Captured footage, will edit and post, very litterally maiden.
First observation - I don’t use 3s so I don’t have any lipos, except I have an old 850mah 3s 25c.
This thing eats it,
Fully charged, 4-5 seconds out the blocks at WOT and I am getting alerts, need better 3s lipos.

Otherwise smooth and agile, a little slower than my 3 inch vandal (jury is out on if that is the lipo) and quicker at changing direction, would be a brilliant indoor racer (don’t mean in the house) but need to sort out lipos to check out outdoor properly
