Taranis x4r-sb poor range
#1
I have to admit that I have went over to the dark side. I just ditched my flysky FS-I6 and got a taranis instead. I must say that the upgrade was well worth it! 

I have stated earlier that I didn't like the taranis but that was after trying it for a couple of minutes and it was not my quad, so I guess I didn't get to enjoy the taranis to its full potential. I must say that my flysky has got a lot of abuse the last year, so I would guess the pots in the gimbals has done it's job, but with the taranis it was like flying on rails compared to the flysky where I felt I had to always do some minor corrections when I was flying. I also find it much easier to fly smooth with the taranis.

But now to the problem. I feel that the X4R-SB has poor range. Several times today I experienced that failsafe kicked in and one thime the quad even fell out of the sky. This was not a problem with my flysky. I guess I was about 150-200 meters away at the most and sometimes failsafe kicked in after maybe 100 meters. I tried with the transmitter antenna lying and standing up and it made no noticable difference. The antennas on the quad is mounted with zipties 45 degrees to each side like most people mount these antennas.

I am assuming open area, no obstructions? Do you have telemetry set up and did the taranis warn you of a weak signal? Batteries full charged in the transmitter? All obvious questions, but someone has got to ask 'em. : )

Open area yes, no obstructions, full battery, and just got a warning once from the taranis. I was flying with friend which also got a taranis with x4r-sb receiver and he has not those issues at that place.

Is it possible that you have an intermittent connection on the RX or from the RX to t he FC?  Are both antennas securely fastened and not grounded out anywhere?  Again, pretty obvious tuff that you've probably already checked.

I would suggest:

0. do a range check with your quad (option in Taranis menu first page), it reduce the TX power to 1/30 so you can see how far you can go with your TX. Compare result with your friend's Taranis if possible.

Also:
1. check your RX antennas, make sure both are in good condition, measure the length of the expose wires too, to be around 31mm - 32mm
2. check RX antenna connectors make sure they are intact
3. check RX output servo cables if they are firmly plugged in

if you also have similar problem with a different quad with different RX, then you probably want to check your TX antenna (need to open the case)

Good idea, I will try to do a range test.

the antennas looked good, but I haven't measured the length of the exposed wires. I guess it should be good, since it is brand new.

There is no connectors as everything is soldered. I even removed the little connector for telemetry, so I could solder it instead. there could be a posibility that it is something there, so I will check it.

Thanks

BTW, how much range should I expect from a taranis and the x4r-sb?

40-50m I would say? Anyway it's safer to compare that with your friends' setup (TX and his RX as well).

also other idea, check where your friend is losing the range (as i expect it is further than yours)...
rebind his quad to your tx and fly to the same spot... (if failsafe kicks in... it is the radio issue, if no problem, look in the rx)
All the best

Today I was out flying the Frankenquad with a X8R, and no issues at all at the same place where I have problems with the X4R. I have placed the antennas a bit different on this quad where one is pointing straight up, and one is pointing backwards.
