Big Grecian,
The flap problem you refer to is the fact that the selctor lever often disconnects/ jams from the electric switch. So while the lever is moved to the up position the flaps remain down, as a result a student can get airborne with full flaps at a low airpseed, the switch suddenly un-jams on the climb out the flaps retract and the aircraft stalls.
However Grecian this is not a reason to not do touch and go's, it is possible to visually inspect the flaps during a touch and go, I always train student to select flaps before applying full power to prevent the above occuring.
