May need to clarify what flaps mean in full size versus RC/Pattern.

In full size flaps usually go down - and I haven't tried that in RC. In RC -- certainly on pattern planes -- the most usual flap application I have seen (and use) is usually both ailerons up. This certainly lifts the nose and is mixed with down elevator to create a slower, steady glide path on landing approach (useful at tight fields, less error prone than side slipping, and lowers likelihood of tip stalling on higher wing loading -- not an issue in pattern, but is in scale!)
