is not really recommended. GoPro cameras have been known to shut down, losing their video
feed, for several reasons (too hot, too cold, dead battery, .. just because it is the third Sunday of
the month…).
To avoid the stress of having to use the Flight Controller’s ‘Return Home’ function to recover a
‘blind’ quadcoper, a secondary FPV camera is highly recommended.
The gimbal was designed for use with the FatShark CMOS camera. Lightweight, and with very
good performance in difficult lighting situations.
A wide­angle lense is recommended in order to let the CMOS camera see the same (or similar)
FPV as the GoPro. This makes framing shots while filming with the GoPro much easier.
Radio Control system
Continuing on the predictable theme, we highly recommend the ImmersionRC EzUHF receivers
for use in the control of the XuGong. These can be easily programmed to emit a PPM stream
from one of the servo outputs, which is compatible with the PPM mode of the Naza controller.
This greatly simplifies wiring, and enables even the 4 channel EzUHF receiver to supply the 5
channels required to fly the quad, plus additional channels for gimbal (and other) control.
Any of the EzUHF receivers, can be used with the XuGong, this list currently includes the 4
channel, 8 channel ‘lite’, and 8 channel diversity.
At the other end of the radio link, there are several radios compatible with the EzUHF. Our
current favourite is the FrSKY Taranis, with our new JR EzUHF Module plugged in the back.
With the EzUHF, even with the 4 channel unit, radio control range will exceed the range
achievable by the quad itself.
For the EzUHF Rx Antenna, a full ½ wave dipole is highly recommended if range of more than a
few kilometers is required.
This antenna can be constructed using the monopole antennas which are shipped stock with the
EzUHF Receivers. Take a length of the cable commonly used for bicycle brake cables, the
same length as the monopole, and solder it to the side of the monopole SMA connector. The
flexible nature of this cable will allow the antenna to deform during takeoff and landing, and fold
out to create a solid dipole during flight.
Mount the receiver on the back of the quadcopter, near the ‘tail’, with the dipole mounted
vertically behind it.
Building the XuGong... Basic Concepts:
Concept #1: Introducing the IRC T-Nut
The IRC T­Nut is a unique design which allows very strong joints between FR4 plates, while
captivating the nyloc nut during assembly.
