I respectfully disagree about making things easier. Sure 800 parameters are too much to set up, but most users can get flying with modifying less than 20. The default parameters are GREAT for ardupilot, and I firmly believe that the user interface is what makes ardupilot more difficult than necessary for new users.
I think over half of the users of ardupilot had no prior build experience with another autopilot, and most all would agree the learning curve is steep. I don’t think it needs to be so steep, and that starts with the user interface - Mission Planner.
