The ImmersionRC Tramp HV 5.8GHz Video Tx is one of the most advanced 5.8GHz Video Transmitter available today. Only 4 grams, and a slender 31 x 20mm, the TrampHV is also a small direct LiPo-powered vTx.

* The USA Version is identical to the International, and EU versions, with one exception. The firmware is region-locked to prevent transmission outside of the USA Ham band. All RaceBand channels are still available, and all power settings are available.

Smallest, Lightest in the Business

This is the smallest, lightest, high-power, high-voltage A/V Transmitter in the business, 31 x 20mm, with a slender 17mm waist, weighing only 4 grams!

Even at this size, the traditional ImmersionRC 5V filtered camera power supply is also included. Twin ground cables from the tiny locking connectors ensure that noisy supply currents keep the camera supply clean.

To cap it off, in addition to running directly from a 2s-6s (HV) LiPo, the TrampHV will happily run from a 5V supply already available in the quad.

Pit Mode

The ImmersionRC TrampHV was the first transmitter to support Pit Mode, which was introduced successfully at the FPVAirShow in France. Pit mode transmits a tiny amount of power on a pre-defined frequency to allow for quad setup at a race event without disrupting the show. Pit mode on the TrampHV is a little different than other offerings, being controlled by race directors transparently at drone races. A race director can stay legal by choosing a pit frequency authorized for use at the event, which can be different for events in different regions. Programmed at the event using the Touch’n’Race wand.

Touch ‘n’ Race for Race Directors

Touch’n’Race, a patent-pending technology which helps both the casual racer, and race directors alike.
Transmitters are placed in Race mode upon arrival at a race event, and remain in that mode until the event is over. Race directors can, without powering up a model, define the frequency and power output of the transmitter, in 5 seconds flat before a race starts.
As soon as the race is over, and the battery disconnected, the TrampHV reverts to it’s race-director defined mode. Massively decreased inter-heat times are possible with this technology, meaning more practice runs, more qualifiers, and races which start and finish on-time (a rarity in the world of drone racing today). More importantly, the chances of a race being disrupted by an accidental power-up in the pits are eliminated, a dream for race organizers.

Touch ‘n’ Race for Pilots

Why let race directors have all the fun?. The personal TNR wand* avoids dip-switch hell even in the local park. Touch-free programming of video transmitters before you launch, eliminating frequency collisions, eliminating the ‘what channel was I on last’ question, and allowing power levels to be modified between flights to adapt to local conditions. Note that the wand is not required to operate the transmitter. A traditional button + LED user interface may also be used to program channel, band, and power level.

Thermally Protected

We have all experienced long delays at the starting grid before starting a race. No airflow over the electronics and video transmitters overheating. Most video transmitters (even the higher end units) have no thermal protection whatsoever and will happily cook themselves and prematurely fail. The TrampHV is a little different. It constantly monitors the temperature of the Tx, and gracefully reduces power output to increase battery life and protect the transmitter. As soon as the props start spinning, it detects the temperature reduction and quickly boosts power output.

Screened for Protection, and Certification

The only Video Transmitter in this size and weight class with a fully screened RF deck, providing protection against dust, dirt and knocks, while ensuring smooth sailing through the RTT&E certification process. An optional plastic case can be easily installed to increase this protection even further, without adding excessive size and weight.

LapRF Certified

The TrampHV was designed alongside ImmersionRC’s RF Lap Timing system, with certified compatibility. LapRF eliminates the need for transponders on the quad for lap timing, and instead uses the energy emitted by the 5.8GHz transmitter on the quadcopter. Two LapRF versions will be available, a 16-channel race version for larger events, and a personal system no larger than a hockey puck for personal use (up to 4 pilots). Both versions sport a wireless connection to a smart phone for timing and configuration.

Anti-Glitch

Another first, introduced by ImmersionRC at FPVAirRace, is technology which allows video transmitters to power up cleanly on their assigned channel without wiping out neighboring channels. Gone are the days when your fellow pilots need to hover safely why you power up beside them. This technology enables asynchronous race starts, where pilots join a race at any time without creating any interference.

Calibrated Power

Each and every TrampHV is factory calibrated to ensure precise power outputs, especially at the critical low-power race levels. No more cross-talk from 25mW transmitters which are instead emitting 200mW!, or worse, 25mW transmitters which emit much lower power levels. No more RF lap timing issues caused by pilots running wildly different power levels.
