I'm only days away from first flight (waiting on current strong west winds to drop for my north/south runway) so I'm doing some taxi testing. Life is good - so much so that a good friend of mine wanted to ride with me and kick the rudders a bit for grins himself. In doing so we discovered an issue - the right hand copilot brake pedal was sticking and would not return. After he kicked the pedals around a bit, the right brake was dragging and quickly got hot. This is not something I would have caught until who knows when...
This is why we test - because we don't know the things we don't know.
