Hi John,
You can get the defaults from Config.h . The description and ranges of all parameters are here: http://code.google.com/p/ardupilot-mega/wiki/APM_Parameters . I recommend looking at Config.h for the particular version of code that you're working with, as the defaults change quite a bit as the team tunes aspects of the code.

JohnB: You can also reset your EEPROM in the CLI, which will take you back to the default parameters. One good trick is to save a config file with the default parameters and then use the Mission Planner's "compare" function to compare it with your current parameters.

Thanks.. I saved what I had 'pre-reset config' and then reset.  Then saved the defaults in a different file 'defaults'.

Now I can pick and choose what it was from the old config I want to keep.  Love this compare feature.

I agree about the search. This is the worst forum I have ever seen when it comes to finding information. They definitely need to get better forum software.

I always use the clear EEPROM method and reload the firmware. After that you can save all the parameters to a file so you will always have a reference. It’s an easy to read text file.

Mike, I wouldn't put it quite so harshly, but I too would like to see the forum split along the different airframes, and maybe now also the different APM's.

I have three APM1's, two that I've upgraded to 2560 boards.

One quad, one conventional airplane, and a third that is to go in either an X8, or a 2.8 meter powered glider type UAV :-)

No way I'm going to dump those, and get APM 2 :-(

The 1280 board flies my foamie perfectly well.

Surely you just need to reload the firmware via Mission Planner ?

When I do that, the software asks/tells me that it will overwrite previous settings, not so ?

Most my post here, I complain about something.. had a crash… loiter did not work..

Well today is different..  Built a new Hex and everything with the flying was perfect. !!!

Super stable, nothing new there…  Loiter worked, can you believe it !!.. 

(my loiter has never worked right because the GPS popped of my AMP2 a while back so I installed an external one MP shows the GPS working, but Loiter was dumb)

But today… with a new APM2…. I did a mission at 1m/s… 120 foot out and back and auto land… Perfect !!!!.. nice and slow

Oh and Loiter… not much wind…  flip the switch… bam.. stays within 10 foot Radius..

Good job guys…. I built and coded an autonomous boat for my research work to survey 24 hours non stop… So I know what it takes...

Can you share your config + PID settings?

i changed only Stabilize P from 4.500 to 3.800

and Rate P from 0.180 to 0.120

because i use T-Motor 2208-18 1100kv with T-Motor 20A esc
