The answer is yes. Molex connectors under the skids have problems. Fortunately, U can still fly without the port cyclic servo. -

With fully calibrated PID loops, IMU & autopilot performance is identical to the embedded computer, in dead calm air. Maybe better thanks to interrupt driven analog sampling.

Raw data from the great beyond & holes for cooling. Standardized on Dean for all power connectors, but unfortunately Dean doesn't have a bolt-on connector. -

The hacked USB adaptors don't fit anymore, so we're another commute away from the next flight. The total for this enclosure with the new USB adaptors comes to $50. -
