Product Support – simply the best.

Though we anticipate warranty work, repairs and parts support will seldom be needed – we always want to ensure our customers are fully protected from any loss of productivity from our electronics. It’s the German way. In this regard, we have partnered with the very best avionics facility in North America – Mid-Continent Instruments & Avionics in Wichita, Kansas – to oversee all warranty and repair work, as well as supply additional parts should they ever be needed.

The engineers and technicians at Mid-Continent work to the most exacting standards in the industry and their reputation is beyond reproach. For us, and for our customers, it’s a little bit of Germany right in the Heartland of North America.

Sales and Distribution – where to buy what we build.

When we set plans in place to bring our products to North America, we knew that, to compete at the highest level, it would be vital to ensure we had the best sales team – and the very best distribution network in place.

We believe we’ve succeeded – and we think you’ll feel the very same way. Please give any member of our sales and distribution team a call at the locations listed below and see for yourself what it means to work with folks who help carry the torch for being Undeniably German.
