2) Install Compatible R/C Receiver
The Vortex is compatible with CPPM (all PPM channels down one single cable) receivers out
of the box, and can support S-Bus, or Spektrum receivers with an optional cable.
It is not compatible with standard R/C receivers with multiple channels of PWM out (standard
servo hookups).
The receiver should be mounted on the rear of the quad, on the shelf provided. A velcro strap,
or a piece of double-sided tape is the best way to mount the a receiver.
EzUHF
Any EzUHF Rx will work, although the cased 4 channel model is recommended for race
quads due to its robustness, and small size.
For the EzUHF, upgrade firmware to v1.52, and setup using the Multicopter button in the IRC
tools. This will enable the UPSTAT channel, which places all uplink status (RSSI, etc.)
on-screen.
Connect CH1 of the EzUHF to the supplied Vortex Rx connector.
DSM/DSM2/DSMX
Unfortunately none of the standard Spektrum™ receivers, including their satellite receivers,
support CPPM output.
One option to fly the Vortex with the Spektrum™ equipment is to use the optional
Spektrum->CPPM cable. Due for release mid-May 2015.
Another option is to use one of the 3rd party receivers, such as the OrangeRx R615X,
available from retailers such as Hobby King, or the Lemon LM0007, from
http://www.lemon-rx.com/
Futaba
Futaba S-Bus compatible receivers require the optional S-Bus->CPPM adapter cable, due for
release mid-May 2015.
FRSKY
For the popular Taranis, and other FrSky transmitters, the DR4-II ACCST receiver is a good
match.
