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 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.

Dynon Certified Announces SkyView HDX Compatibility with Trio Pro Pilot Autopilot

We are excited to announce FAA approved compatibility of the Trio Pro Pilot Autopilot with Dynon Certified SkyView HDX systems. This integration allows even more pilots the ability to pair a new SkyView HDX avionics upgrade with an approach-capable, two-axis autopilot in their type certificated aircraft.

Dynon / Trio Autopilot Compatibility and Capability Highlights

  • FAA Approved Integration: With Trio’s recent approval, Dynon SkyView HDX may be connected to the Trio Pro Pilot autopilot system, allowing it to follow guidance from SkyView HDX and connected external GPS navigators.

  • Approach-Capable Autopilot: When a compatible IFR GPS Navigator is installed, the Trio Pro Pilot can fly fully coupled approaches.

  • Full Trio Aircraft Model Line Coverage: This approval includes all type certificated aircraft models the Trio Pro Pilot is available for, adding dozens of models that can now benefit from installing a Trio Pro Pilot Autopilot alongside SkyView HDX.

FAA Approved Integration Features

When connected to a Trio Pro Pilot autopilot, SkyView HDX can serve as a single-entry point for heading, barometric altitude, and altitude pre-select. The configurable “bugs” that pilots set on their SkyView HDX system are automatically sent to the Trio Pro Pilot, allowing it to fly the guidance directly provided from SkyView HDX. 

Additionally, when a compatible IFR GPS navigator is installed, the Trio Pro Pilot and Dynon SkyView HDX combine to provide full GPSS course guidance and auto-sensing for autopilot course and descent guidance during RNAV approaches. This allows pilots to fly fully coupled IFR GPS approaches with their integrated SkyView HDX and Trio Pro Pilot system.
