Range test

Hi all,

Feel like this is a really basic question but I'm struggling to find any obvious answers although I'm putting it down to it being subjective.

How the hockey do I figure/work out my TX range? I've got my failsafe set up but I still worry myself when I fly a bit of a distance. I come from practicing with a Hubsan X4 so range was never an issue on that as it used to get blown away going outside.

My TX is a Jumper T16 and my current RX is a FrSky R-XSR.

If we pretend it's a nice sunny and clear day with a flat landscape... what can I reasonably expect? I found this video below but that sort of distance seems insane! Is that really the range it could hit!?

I don't even intend on flying far but would just like to know.

Cheers!

The R-XSR has telemetry so your tx should have an rssi signal. You should be able to set a low rssi warning on your tx. If you are flying fpv then you can have rssi fig on the osd. You should worry when rssi goes below 50.
Normally there is also an rx range option in OpenTX that. I think puts out 10% power so you can physically do a range test in a field then multiply by 10 to give you range.

Just to give you an idea of range an r-xsr is a full range rx that should give 1km as long as there is nothing in the way or interfering with it.

Yeh I have it setup on my T16 and I've set it up to read it out loud when I hit a switch (which is handy). When I get my goggles through I'll be setting it up on the OSD.

Ok that makes loads more sense! I found that range test feature, walked off from my quad and couldn't believe that I was only able to get like 20m away until it started saying the signal was low! Multiplying it by 10 makes sooooo much more sense now! 

Thanks a bunch as always!

Happy to help mate.
You can set the t16 to read out rssi by setting the warning level. Then if it drops you will get an automated notification.

interesting video, thanks for linking it.  I was pretty surprised at the range on 2.4GHz - I read some of the comments & the verdict seemed to be the low background RF interference from the remote location & good model antenna placement.
