I have purchased several of your F9P RTK units with the internal RM3100. I am very pleased with the GPS accuracy and performance however lately I’ve run into some issues with the accelerometers on the bottom side of the GPS board. As you can see from the picture they are mounted extremely crooked. I have at least 4 units that look like this.
When the accels are off level by this much it really messes with my aircraft. Last week I put a brand new F9P on my aircraft got everything calibrated and the ground/speed would just keep creeping up and up while the aircraft was sitting still (up to 600MPH). I opened the GPS looked at the accels (which were very crooked) and switched out the F9P to another new one with more level accels and the issue went away.
Why are these so crooked?
Do you expect it to be an issue when calibrating an aircraft?
Do you consider all these units defective?
Any info would be very helpful.
