Hi All =96

 

I spent a year in Ohio last week fixing my plane.

Those dastardly Bosch

Lessons learned

For those of you who are still building, think long and hard when selecting components, especially those which are single-sourced or unique such as = avionics. Stick with tried-and-true products from well-established vendors. =

 

On a brighter note

Performance
