I've done it both ways and have had good and bad gliders built both ways. I think Stan's Slow Poker started this method. Drela's Upstart has full span flaps. Two of the talking points for the rigid tip are that it produces washout in the tips (relative to the rest of the wing) and helps control vibration of the flaps.

Subject: [Indoor_Construction] Std. Catapult glider
All the category 1 flapper type standard catapult glider drawings I have seen show the training edge flapper free to flex except at the wing tip where it is attached to a ridged wing tip section. This would seem to limit the ability of the flapper to flex. I am curious why this is? Wouldn't it be better to not restrain the flap at all?
