Mapping Mission with APM:Plane - Survey(Grid) works with APM:Plane?

Hi,
First at all: happy new year (=

I would like to ask:
the Auto WP>Suvery (grid) option on the Flight Plan screen on Mission Planner, works well also with fixed wing aircraft?
I am talking about this:

I have already tested several times with multirotors drone, but I never tested it with fixed wing drones.

Can you tell me if it works well with APM:Plane?
The fixed wing drone do not have problems during the turns?
It can reach every waypoint without problems?

Hi! It works flawlessly, but make sure you do not exceed the maximum number of waypoints. It is also not clear if the DO_DIGICAM_CONTROL problem have been resolved in Mission Planner:

http://discuss.ardupilot.org/t/camera-trigger-problem-by-do-digicam-control/7304
https://github.com/ArduPilot/MissionPlanner/issues/1413
So I would suggest doing camera triggering based on distance.

Thank you very much for the explaination (=
Thank you!

But I have three other questions:
1)It works well also with plane?
2)With APM:Plane 3.7.1 the DO_DIGICAM_CONTROL issue is present?
3)What is the maximum number of waypoints?
