It is very very easy to demonstrate adverse aileron yaw in any aircraft - merely reverse the aileron before the into turn yaw follows....and then reverse again...and again...and then get them to start using rudder to counteract this so the nose rolls through a point on the horizon - this technique works for every a/c ive met from microlights to twins.
Yes I do teach adverse yaw as a secondary effect of aileron - and a further secondary affect is yaw into turn....that way there is no confusion - especially when they know why the first and second yaws occur - an easier way to show into turn yaw is to raise the nose a little before applying ailerons - doesnt half make shoing yaw easy!!!
