‘Baby Tramp’

The Long Overdue Baby Brother to the Tramp HV

Highest Power in a Tiny Package

Only 18x13mm, and weighing in at a paltry 1.01g, the Tramp Nano packs quite a punch. Given adequate airflow, output powers of > 500mW (typically 700mW+) are emitted.

Following in its big brother’s footsteps, the Tramp Nano includes high-speed automatic temperature regulation, which avoids overheating transmitters on the starting grid, or after an unexpected landing with lengthy recovery (also with the advantage of saving precious battery power while transmitting a signal for recovery).

The Nano operates from the 5V regulated supply that most flight controllers supply these days, and doesn’t require a dedicated connection to the flight battery.

20 x 20mm Carrier PCB + Gummies

Included with every Tramp Nano is a lightweight 20 x 20mm carrier PCB, with IRC gummies, suitable for M3 screws.

Three touches with the soldering iron, and the Nano is soldered into place, without the need for header pins.

Included silicone ‘gummies’ protect the transmitter against the extreme shock of collisions common in FPV racing, and freestyle.

The carrier PCB also acts as a heat sink, allowing higher powers to be used for longer time periods.

RGB Status LED

Was that one red flash? or two?… maybe one short red flash, or two short red flashes… those days are over.

The Tramp Nano sports a tiny RGB LED capable of showing transmitter status without decoding flash codes.

Green LED? all is well, transmitting normally.

Flashing Green LED? Pit Mode.

Flashing Blue LED? Race Locked, Tx not active.

Flashing Magenta LED? Race Locked, Tx transmitting.

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 Tramp family 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.

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.

TNR MiniWand

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.

Flight Controller Integration

As with its big brother, the Tramp HV, the Nano is fully controllable using the same ‘Tramp’ protocol supported by all of the main Flight Controller firmware.

Additional commands eliminate the need for a ‘pit switch’, since the vTx can be completely shut down from the Flight Controller.

Keysight Power Meter

Calibrated Power

Every member of the Tramp family ever shipped has been 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.
