This small video is from this summer. Don't mind the music. Take a look at what happens at 23-24 seconds when I throw the plane.
Flap flex is alarming. This was in almost zero wind with good servos (DS3288) and not too sloppy linkage. Ailerons have obviously much less flap.
At the end of long launch you can also see change of launch camber. Normally I do this at much more early stage, maybe 1-2 sec. Using 2 stage camber improved my launch and made it more adaptable to variable conditions.
