SKU: N/A Category:


The large, full color, sunlight-readable display means that the pilot can view far more information at a glance than conventional displays. The touch screen gives the pilot far more control over the instrument than conventional button instruments. No two pilots have the same needs and the Oudie 4 addresses this with unparalleled user customization.

The Oudie 4 Basic is a lite version of the Oudie 4 and is ideal for the recreational pilot who wants the most advanced instrument but does not yet need competition related data-fields, task options, user-profiles and FAI Trinagle features. The Oudie 4 Basic has the same fantastic hardware as the the Oudie 4 which means that it can be simply and easily upgraded at any time with the purchase of a software unlock code.
