Thank you for your purchase!
Thank you for choosing our mod and we hope you will enjoy it as much as we do!
This guide is intended to help with the installation of your new mod kit and get you flying
ASAP. It has been carefully constructed to make the procedure as straight forward as
possible and should have no trouble at all. If you do, please do not hesitate to contact us.
We would also like to take this opportunity for thanking Miru and Pawelsky who did some
amazing research and development to make this method possible for the community. XR4Drone would not have been possible without their insights!

The compatibility of the mod with your TX (Transmitter) depends on which version of the
XR-4Drone you purchased. Each version has its own specific RX (receiver) which operate on
their specific frequency and modulations:
DX5e*
More to come…..
* Please note that the DX5e's trainner swtich is actually a 6th channel. It is used to change
flight modes therefore, needs to be replaced for a ON-ON switch(Futaba 3M94A00805).
Please email me for more information.
****VERY IMPORTANT: NEVER POWER THE DRONE VIA USB AND BATTERY AT THE SAME
TIME! YOUR DRONE WILL BE FRIED!

Please Note:
There are 2 ways you can get power to bind. You can either plug in the Drone Kit to the drone, and powering with
the battery. Or you can plug via the USB connector on the Arduino to your PC.
