Hello setup my APM on my quad in x mode loaded the latest from the Mission Planner went through setup in CLI and test flight was good a little wobble so Lowerd stabalize P to 5.0 and raised D to .14 left I at default and second flight very stable decided to try loiter. Had a little up and down but baro is not covered with foam yet but pretty decent. But wonders around alot. If I up the P for loiter on Lat and Lan will this help it keep a tighter box?
Running the latest code from Mission Planner I have not seen any yaw issues at all it is rock solid.

Could some of these problems be due to radio inaccuracies? On my 12fg the centres are at about 1496 except elevator is putting out 1515. My turnigy is different between stock and er9x, but at least er9x has stick calibration. However, swapping the turnigy from 2.4Ghz to LRS module also changes the centre points.
Maybe we should use subtrim to set centre to 1500 in cli for the four primary channels.
Another solution could be for the code to capture the centre points during setup.
For anyone seeing different behavior in different modes, don't forget that most radios default to remembering different trim settings for each position of the flight mode switch. Could be a trap for beginners.
So Can some please confirm I am doing this right in the code,
As it dosnt seem to be working well.
Ok for a 6 channel TX,
from control_Modes.
if (g.rc_6.control_in > 800){ // is this correct???for 6th channel radio
if (g.rc_7.control_in > 800){ //is this correct ??? for 7 channel radio
and uncoment this line
//trim_accel();
And on the sensors page ,when selecting the 6th channel ,all the green bars light up,Is that what is considered High?
Any help would be great.
Thanks
I understand keeping some features disabled during Beta or for the purpose of "protecting" an entry level flier. But maybe having a "advanced" Tab in the Configurator with check boxes to turn on less understood options. This way the project can advance and be tested without causing confusion for casual fliers.
With coders abilities to offer advanced tools like inflight accl calibration, it would be nice to have these available in some way in the config.
I offer my thanks for the work being done and making this an enjoyable hobby!!!

Is there any way to do this with a six channel TX .
As I have the same problem>
The quad moves forward ,even after calibrating.
So with a six channel TX can I re -calibrate the Acc in the air,
Or do I need a 7 Channel.
I am alittle confused,
Do the radio trims have to be centered ,before GPS works?
I'm about to test some setting to prevent Loiter oscillations. Will report back in an hour.

"If you have trouble holding Loiter, return Nav_Loiter_D to 0 using the planner.
And here's something you can try to improve your waypoint travel: Filter the pitch amount in WP navigation.
In navigation.pde:
New:
nav_lat = nav_lat + g.pid_nav_wp.get_pid(error, dTnav, 1.0);
nav_lat >>= 1; // divide by two
old:
nav_lat = g.pid_nav_wp.get_pid(error, dTnav, 1.0);
If you have WP navigation issues, you can just uncomment the unfiltered version.
