Parameters' names and ranges have changed?

ArduCopter Copter 4.0
1

I have a quadcopter “Tyro129” with “MATEK-F405” board and in this post -On a low-cost/mid range FPV Arducopter , there is a list of parameters that I need to define, but I have two problems:

  1. In this list, some parameters have value higher than I can enter, for example:

ErrorMax
ErrorMax1344×816 196 KB

  1. The names of some of the parameters in my firmware version are slightly different from those that appear in the list, for example:

ErrorName
ErrorName1632×1056 183 KB

When I tried to guess the real name of the parameter - I got something similar, but I’m afraid that it is a different parameter, for example:

WithoutI
WithoutI1058×662 114 KB

Are those changes in the names and ranges of those parameters due to version upgrade?.. I doubt it, because I took exactly the version that the author of the post has mentioned (4.0.0), and also two other versions (4.0.5 and 4.0.2).

Or maybe there is another reason?.. And how should I convert those parameters values to fit into the ranges in my current firmware?

Thank you in advance.

My guess is that ATC_RAT_RLL_FILTT is just a typo. I think you have the right parameter.

The recommended values are just that, recommended. You can exceed them if you know what you’re doing. If QGC won’t let you then you may need to use Mission Planner.

In Arducopter 3.6 those params were spelt “_FILT” and in 4.0 onwards they are “_FLTE” and “_FLTD”

It looks like the ranges mentioned in the UI are not recommended ranges but rather min and max allowed values, i.e. I really should not deviate from it. See in my first picture above the ATC_ACCEL_R_MAX parameter. The QGC says that its allowed range is between 0 and 180000 . But the author suggest to enter a much higher value.

Usually the groundstation software, QGC or MissionPlanner, have suggested ranges and you can enter whatever values you need to.

Use this spreadsheet to calculate the required values, download a copy:


and go through the tuning guide:

This is because the GCS has not caught up to current Ardupilot features/functions. Don’t worry about it.
