Quadcopter Range Hack





Introduction: Quadcopter Range Hack

The default control range of the Syma X5C drone is only 30 meter, adding a true 2.4ghz antenna you can double this range.

Step 1: Find a 3db - 5db 2.4 Ghz WIFI Antenna

You can buy one, or remove from an old WIFI device.

Lucky for me, I found a bricked WIFI access point.

I removed the antenna from it.

Step 2: Open the Syma Transmiiter

This is a very easy step, don't forget to unsolder the power wires.

Remove the original antenna (that 2cm wire).

Solder the new WIFI antenna in the Syma X5C transmitter.

Step 3: Reasamble the Transmitter

After you checked everything, you can solder back the power wires and reassemble the transmitter.

The new transmitter looks good with the new antenna, and also has a better control range.

Hey there, is there any way to drive the quadc with any kind of wi-fi module and arduino, instead of its remote?

When i click on your link that is at the end of your instructable that says read more, it takes me to an adult site.

Hi. I ordered a 5 db antenna off of banggood.com it is longer than the one you used. Does this matter?

Hi everyone,

So I am performing the antenna mod on an HS200. I am able to easily identify the antenna however I am not sure of the solder point on the board for the ground. Is it recommended at all to ground directly to the negative battery terminal ?

Any advise would be greatly appreciated. Here is a pic link: http://bit.ly/2kRqSB1

Best Regards,


I had the same problem. I indeed made an extention wire to the ground entrance of the battery on the circuit board. Now idear if that is "allowed" but it seems to work well.

i have tried this mod on syma x5sw .. but seems doesn't work :( when i
turn it on, the only thing happen is the LED lights up, but not
blinking like searching.. and no beep sound, also LCD is gone too ...
please help if you have any idea

I think your signal wire is touching the ground.

1. Check all connections.

2. Check actual lenght of unschielded part in antenna.

hey guys,will a 2dbi antenna work?

some mods can make it 300 meters and some other add 1500 but i prefere to keep it safe and make this mod because i think that more range makes it more uncontrolabe

This mod didnt really change much range wise, it made it worse/better in some parts
