Planned obsolescence is immoral in concept. At TQ, we don't design our aircraft electronics with an expiration date. It's kind of a German thing. Whether it's componentry flying in the world's leading commercial aircraft, or our KTX2 transponder and KRT2 transceivers for the general aviation fleet, we create equipment to potentially outlast its aircraft. Our reasoning is simple: The integrity of your avionics should not occupy your thoughts during flight. So, we are committed to producing the most elegantly efficient, lightweight but durable products available. Partly precision instrumentation. Partly heirloom. Undeniably German.
