1) Install Compatible R/C Receiver
The Vortex 250 Pro is shipped with three receiver interface cables, one for CPPM, one for S-Bus,
and one for the Spektrum receivers.
Cleanflight provides a list of receivers stated as working, so please check if yours is listed
here: https://github.com/cleanflight/cleanflight/blob/master/docs/Rx.md
CPPM
As it ships, the CPPM cable is pre-installed in the quad. If a CPPM receiver is to be used (such
as the EzUHF, or other CPPM receivers on 2.4GHz) the receiver can simply be attached to the
rear mounting plate, and the cable connected. No other cabling is required.
CPPM sends all PPM channels down a single cable, and eliminates the mass of wiring that
most mini-quads have to contend with.
Note that the Vortex 250 Pro is not compatible with standard R/C receivers with multiple
channels of PWM, each connected via a separate cable.
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.
SBus, or Spektrum
To support one of these receivers, a cable must be installed in the quad, which does require
removing a few screws to access the connector.
