Today I opened my Syma X5C 2.4Ghz remote controller. The default range is only 30m and I want to extend this range adding a 3db 2.4Ghz antenna.
I think it’s very easy to replace that fake plastic antenna with a 3db 2.4Ghz from an old wifi router, or you can order one on ebay for only $6.
I think this hack will increase the range of the Syma X5C up to 100 meter.
After I get my antenna and make the mods I will come back with a step-by-step article about this transmitter hack.
On the bellow you can see some image from inside the Syma X5C remote controller.
If something will go wrong you can order another remote controller for $16 here
