Charging Mod for Cheerson CX-Stars (aka Floureon FX-10 and DHD D1)


The CX-Stars is an insanely fun to fly quad that fits inside the transmitter, which can then fit in your pocket. However, the quad can't be charged through the transmitter, it uses a special USB cable that goes straight from a USB port from whatever to the quad. To mod this quad to perfection I decided to build in a charger into the transmitter.

And you're done! You should see a red LED when the switch you installed is turned on, and then a 2nd red LED when you plug in the quad to charge. The 2nd red LED should go off when the quad is done charging. If you can't see the LED through the plastic, just drill two small holes in the back over the LEDs. If you are concerned about the AAAs running out too quickly, grab a couple energizer ultimate lithium, which last around 5x as long as alkaline.

Another mod that has been done to this quad is increasing the range by adjusting the antennas. See the 2nd post of this thread for more info https://www.rcgroups.com/forums/show....php?t=2518729

Let me know if you have any suggestions for improving this mod!

To make it a little cleaner I put the green plastic piece back in, but with a small hole for the charging cable to feed through.

Note that it is also sold under the name Aerix AERIUS and SKEYE Pico, although those companies are charging twice as much for their brand's version, so don't get scammed. Current cheapest shipped from US seems to be banggood at $15.50 http://www.banggood.com/D1-Drone-Min...-p-986728.html
