Eachine E011 Mods: Stock Transmitter Range Modification

Want to increase the range on your E011 toy transmitter?

Di-Pole antennas like the ones on the E011 and in the E011 receiver work best when they’re oriented in the same direction and when the tips of the antennas are never facing the TX or the RX. I’ve also found that they work substantially better when they’re not flat against a circuit board. I don’t know the technical reason, but I know it works in the real world :).

This modification has been detailed elsewhere and is generally possible on nearly all toy grade micro quads, as long as the antenna on the flight controller and the controller are not integrated into the circuit boards.

On the E011, the flight controller antenna is usually laying flat against the flight controller. Simply standing it upright makes a massive difference in signal quality. You can make a hole in your camera’s canopy or in the stock lego board to allow for this. You can also simply stand it up if you fly with the circuit board bare. Keep in mind though that if yo have to keep moving it back and forth you’ll eventually break the solder joint, so try to find a way to secure and protect the antenna in it’s upright position.

On the toy transmitter, you’ll need to remove 3 screws to access the antenna.

Usually it’s wrapped around itself on the backside of the circuit board. Simply unwrap it and then make a small hole in the top to run it through. I used a xacto knife and simply spun it around a few times to create a tiny hole to slide the wire through.

Once you’ve slid the antenna through, you will likely want it oriented upright as shown.

I will post a video shortly comparing the distances reached with each configuration, as well as with a transmitter modified with an aftermarket antenna.

While you’re at it — why not make the E011 toy transmitter quieter too?
