after installing new plane firmware does it overwrite existing parameters, using mission planner?
Only under two circumstances:
If the function or usage of a parameter has changed as a result of a patch/fix/enhancement. There’s a conversion to change your old value to whatever the new corresponding value should be. These are usually few and far between.
If a parameter’s default value changes, and you still have that parameter at it’s default value (unchanged by you), the new default value will be applied.
Other than that, any parameter you have set will remain set through firmware upgrades/downgrades.
I just used the compare function and does not show many differences.
So believe I am ok.
Thanks for the reply
