darock,
the easiest place for them to bend is not directly along the axis, but it is very close. if it were a sport plane or something, i would say that is un-acceptable. but fact of the matter is, it is a trainer. you will not have much deflection, you will not draw much power, centering will not be an issue and i can not remember a single instance where i have heard of CA hinges failing on a trainer type aircraft, namely for those reasons stating above

i however would not fly it in that state, i am just stating that it will work.
