usb data transfer cable

[emm]

i need to control a raspberry pi 3 based quadcopter wirelessly , but it doesn't seem to work well with radio gudgets as it's does only cover a very low distance ( like 1 m ) , so instead , i'd like to at least start to control it with a cable , but i don"t seem to find a compatible data transfer cable for raspberry pi 3.
p.s / i'd propably connect the r-pi to a linux pc

... Having a quadcopter tethered by wire doesn't seem very practical at all. With your range limitation of only about a meter I'm assuming you're using the Pi3's bluetooth interface ? ... I'd suggest using it's WiFi feature instead, that way not only would you get better range,
you'd also be able to incorporate "off the shelf" subsystems for the quad more easily

yes i'm using a pi3 .. when i considered the usb cable , i intended to extend it of course to have a wider range, and it's mainly when i'm still working on its stabilisation , i'd prefer if it's attached to a cable so i can have a better control over it in case of a crash
i'm not considering the bluetooth , it's impracticle for my application , instead i might use wifi tongle , but , the problem is that i need to test the quad in a place where there is no wifi network nor 3g , so i need to use radio communication ..
any suggestions ?

... To test it and assure there's no interference then USB cable is good, but to fly it radio is really the only choice.

I wasn't suggesting bluetooth, I was asking if that was what you had tried since you said you only had one meter of range.

Usually RC planes and Quadcopters run on 2.4 GHz for control and 5.8 GHz for Video, but there will always be
the concern for interference doing that. There are long range radio links you can purchase that are UHF based
that will not only limit the chance of interference found on 2.4 GHz, but also gives you much more range too.
Just look online for UHF radio control links and interface one of those with your arduino flight controller
