Trig Launches TT23 Transponder

Smaller, Lighter, GPS, ADS-B Out, Certified. 

Trig Avionics, a Dynon Company, is delighted to announce the launch of the TT23 Compact Transponder — the next generation of Trig’s compact line. The new transponder module design is smaller and up to 15% lighter than its predecessors, reducing weight and space needs while introducing new capabilities for pilots worldwide.

The TT23 is a fully certified Class 1, Mode S transponder with ADS-B Out, suitable for both VFR and IFR flight. For the first time, it is also available with optional built-in GPS.

The TT23 builds on the success of the popular TT21 and TT22 transponders, retaining the same user-friendly controls that pilots know and trust. The new models include a built-in altitude encoder and feature a bright, easy-to-read LCD screen for intuitive operation and dependable performance.

The TT23 and TT23G are available now through Approved Trig Dealers worldwide. 

TT23 Model Lineup

TT23G: The TT23G features a built-in GPS receiver, making it the ideal choice for pilots seeking an integrated ADS-B out solution. The TT23G is perfect for experimental and light sport aircraft looking to meet the requirements for ADS-B out in the United States. In markets where ADS-B equipage is voluntary, the TT23G offers enhanced conspicuity and safety.

TT23: The TT23 is the same compact transponder without an internal GPS. For aircraft with a suitable GPS position source on board, the TT23 can be used as an ADS-B Out solution – including type-certificated aircraft in the US. An STC will be available to integrate with popular third- party GPS navigators, as well as the Trig TN70 Remote position source. For those that do not intend to equip with ADS-B out, the TT23 model is a high-quality, modern transponder with easy configuration options that make it suitable for any application.

Dynon Avionics is excited to announce a strategic investment in Trig Avionics, a UK-based manufacturer of transponders and communication radios. This investment brings Trig into The Dynon Group of companies and strengthens a long-standing partnership between the two innovators in general aviation. 

Trig Avionics is a European manufacturer of avionics, with a focus on transponders and other radio-based products. Trig has earned a reputation for designing and manufacturing high-quality, compact, and energy-efficient avionics. Since its founding in 2004, Trig products have been trusted by pilots across a broad spectrum of general aviation aircraft, from light aircraft to helicopter
s and gliders.

For many years, Trig has supplied Dynon with private-labelled radio transceivers and transponders that integrate seamlessly into Dynon’s SkyView and Advanced product lines. This strategic move deepens that collaboration, allowing the two companies to align more closely and deliver an even broader range of avionics solutions to customers around the world.

The Dynon Group, now including Trig Avionics, will continue its mission to bring cutting-edge, reliable, and affordable avionics to general aviation. The combined entity will be led by Brad Thurow, who has been appointed Dynon’s President. Formerly the Vice President of Engineering, Mr. Thurow joined Dynon four years ago as part of a planned succession strategy.

Dynon Introduces Corgi Trim Servos

Dynon, announces its new line of Corgi Aviation trim servos for experimental and light sport aircraft.

Corgi servos are designed to electrically move trim control surfaces and other systems in homebuilt and other light aircraft applications. In modern homebuilt and light sport aircraft, they are commonly installed alongside complete avionics + autopilot systems such as those available from Dynon and Advanced Flight Systems. When integrated, they enable autopilot auto-trim capability, which automatically trims the aircraft when under autopilot control. Corgi servos can be installed in any aircraft where electric trim control of a trim tab is desired regardless of avionics selection.





Originally developed in collaboration with an aircraft manufacturer, Corgi servos are flight-proven. They are installed and flying in over 100 S-LSA aircraft, and have proven to offer exceptional performance and reliability.


Corgi servos are available in six models, ranging from 0.7” to 1.2” of travel, in both clevis and threaded end varieties. They include both sides of the electrical connector and the pins needed to finish the aircraft side harness for easy connectivity. Internally, Corgi servos feature limiting switches to electrically inhibit motion at the ends of their range of travel. The output shaft is brass for enhanced strength and durability.


Corgi Aviation servos are available from Aircraft Spruce, directly from Dynon, and from other Dynon resellers. Models range in price from $199 to $269.
