Hybrid v2 Uno/Duo

Single board Control and Downlink…

Doesn’t Get Much Simpler…

There is nothing like the experience of flying an FPV drone, but building these marvelous machines is more complex than it needs to be.

With Tramp we set out to raise the bar on video transmitter technology. With Ghost we set out to redefine the norms in receivers for R/C control. And now we have fused these two together, in the groundbreaking Ghost Hybrid v2.

Designed by pilots, built by pilots, supported by pilots.

Best Race Control Link PERIOD!

A combination of two full receivers (Duo model), and the unique ‘Solid250’ mode, fuse to provide the most solid race control link in the business, with no competition in sight.

Racers at the higher tiers of the sport can’t afford lost packets, and tradition R/C links just can’t deliver a solid link. The Ghost Duo, with Solid250 RF mode uses receiver diversity, temporal diversity, frequency diversity, and polarization diversity simultaneously to guarantee an absolutely solid link.

Developed with the help of the unbeatable XBlades team.

Intelligent Video Tx Control

Intelligent, and direct control of the video transmitter from the Ghost ecosystem. Use either the OLED menus on the Ghost Transmitter module, or the responsive OpenTx tools menu.

Tx remains silent on power-up, shuts down immediately in an (unlikely) failsafe.

Native Team Race Support

During team racing pit-stops are as adrenaline fueled as they are with Formula 1 racing.
Pilots need to get on the ground, and their team-mates in the air as quickly as possible, and with the minimum fuss.

The Ghost Hybrid is the first and only product to natively support team racing, without the help of a flight controller.

Split-second transmitter shut-off, and instantaneous power-up of the following quad are truly best in class, as shown by a 1st place win at the MultiGP Mayhem 2021 edition.

The best part… no complex configuration, just bind, assign switches, and fly.

qTee Antennas

qTee, a.k.a ‘Cutie’ antennas are center-fed dipoles, with integral balun to ensure no cable radiation, and without unexpected nulls in the radiation pattern.

Tip to Tip length of just 60mm, easy to install in anything from a Whoop™ to an X-Class quad.

The Duo version of the hybrid ships with two qTee antennas, which may be installed orthogonal to each other for polarization diversity.

A troubleshooting guide for R/C Control to Flight Controller may be found here.


WARNING: While full Ghost support will be part of OpenTx 2.4 release, below are custom 2.3 builds of OpenTX that allow you to benefit from Ghost module and protocol today !


The most complete support for the GHST protocol is currently in the latest ‘development’ build which be installed using the betaflight configurator.
Turn on the ‘Enable Expert Mode‘ switch in the firmware update page, and select ‘Development‘ in the selection bow below.

The latest version of the Betaflight Configurator, with the ‘GHST’ option in the protocol selection dropdown may be downloaded from here.

Note that if you are uncomfortable running a development build, consider using the SRXL-2 protocol with one of the official betaflight release builds. 



Release notes for Ghost firmware may be found here.
