From the engineers who changed the Analog FPV world with rapidFIRE, comes the Ghost to set a new bar for R/C Control technologies. Go faster, further, safer.
Three years in the making, countless fun-filled hours of testing by the world’s fastest pilots.
Ghost is a 2.4GHz Radio Control system for R/C Model Control, with a focus on the FPV community.
Designed for both reliable control at extreme range, and extremely low latency with best-in-class frame rate for the Race circuit.

IRC Ghost is PFQ (Pretty… Quick)
Choose from several modes of operation in your Ghost Transmitter. The slowest of the two Race modes run at 160Hz frame rate, while the fastest ‘Pure Race’ rate opens the throttle to 222.22Hz frame rate.
OpenTx to Flight Controller latency is expected to run below 4ms.
Can racers feel this? A good question to ask… but maybe a better question is whether you want to race against a pilot which is using it…
2.4GHz And Long Range Capabilities
ImmersionRC is setting a new standard with its Ghost system serving both the needs of Long-Range pilots, Freestylers, and Racers.
Easily achieve ranges of 10s of km with equipment light enough, and antennas compact enough, to perfectly accompany your Nano Goblin™ into the neighboring country.
Since 2.4GHz antennas are relatively small, a directional antenna on the transmitter can easily double the expected range.
‘Micro Failsafes’ – Never Again
The EU-legal 868MHz is a paltry 2MHz wide. Packet loss with even 4 pilots in the air is not pretty. Add another 4, and racing isn’t fun anymore.
The USA-legal 915MHz band is a little better, at 15MHz wide.
The Worldwide 2.4GHz band provides 76MHz of bandwidth, and will comfortably house countless simultaneous links without large numbers of lost packets.
With recent enhancements to Flight Controllers (feed-forward) providing superb performance, but quite sensitive to packet loss, every little bit helps.
Ghost Modular Transmitters
The first Ghost Transmitter is a ‘JR’ style module, with integrated OLED display and Joystick. Configure it seamlessly without the need to interact with Lua scripts.
Depending upon region, up to 350mW of RF power may be emitted through two supplied short-dipole antennas. Antenna diversity is the default mode of operation, but single antenna mode is a menu option away.
A simple menu system shows all critical parameters, including a spectrum analyzer, and a real-time display of system latency, from R/C Tx to Flight Controller.
Size matters. The Ghost Átto receiver weighs in at about 0.6g and is only 14.8 x 11.5mm, a 15% smaller footprint than its closest competitor. The Ghost Zepto receiver is even smaller, coming in at 10 x 10mm and weighing only .38g. Options are always a great thing.
Most standard protocols are supported, including PWM, SBus, Fast SBus (200k), SRXL-2 (400k), and an inverted SBus (or rather an inverted-inverted SBus) to increase flexibility with F4 FCs.
Deja-Vu binding ensures that receivers already ‘known’ by a Ghost transmitter (through a previous bind operation) no longer require a button press to bind them. This also goes for new receivers, which will bind for the first time without the need for the button (all of this because we can’t stand tearing models open to find that buried bind button).
Orqa Goggle Integration
That space on the FPV.Connect board… yeah, that is for a Ghost receiver, the Átto.
Ghost transmitters and receivers can form a network, without the need to use Bluetooth or wifi, and communicate between themselves without sacrificing critical control performance.
Clear channel scan with automatic channel assignment, auto-start DVR recording when throttle stick is raised, and a bunch of other cool features planned for 2020.
Simple PCBs designed to dramatically simplify wiring, mounting, and cooling of Tramp Nano + Ghost combinations.
36×36 single-sided, 20×20 double-sided, 20×20 single-sided, ‘Toothpick style’, and a special version designed for the Five33 Tiny Trainer.
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
GPS + Noise
Another advantage of running 2.4GHz instead of the more traditional sub-GHz frequencies for long-range is that 2.4GHz has no harmonics that can desensitize GPS receivers (which are in the 1.5GHz band), so GPS position fixes become more precise.
In addition, Drone/Quad/UAV electrical noise due to fast switching signals is broadband, and also sub-GHz (typically sub-500MHz), and doesn’t desensitize the 2.4GHz Ghost receiver.
