Repairing the Syma X11 Quadcopter


When unplugging a battery from the Syma X11 quadcopter one of the power lines became disconnected. The old solder and broken wire needed to be desoldered and removed. The wire was then re-attached. Since the quadcopter was open I drilled a small hole in the casing and let the antenna wire out to see if reception would be improved.

Antenna Modification for Syma X5C Controller


In an attempt to increase the range of the RF controller for the Syma X5C quadcopter controller I removed the 28 mm antenna with a Linksys WRT54 WiFi router one.

The new antenna works but I did not do a range test with the old antenna so I am not sure if it is about the same, better or worse than the new antenna. I did not modify the antenna in the quadcopter.

The router is 802.11b model so it could not be used securely anymore as a wireless router since it used only WEP. I could not flash upgrade it so I removed one of it's antennas.


The top of the antenna is threaded so it can be removed when storing the controller. In order to get it to fit in the snugly in the casing, the bottom section of threading needed to be wrapped in electrical tape to expand the diameter of the connector.
