anything that evens out the trim differences at differing speeds -is good.
A high wing model -- has all of the lift/drag above the thrust line - which makes power applications tend to INCREASE the upward angle of the craft .

by pointing the propeller downward quite a bit -- the forces can be balanced out --somewhat .
basically the crummy semi symmetrical wings on trainers add to the problem.
a nice symmetrical wing on a very low wing loading model -again a high winged thing - makes for much easier trim relative to speed
the plane will fly just as slowly as the supposed trainer airfoil.if wings are the same size/shape.
Learning the nuances of speed trimming whilst learning to guide the model around -is a bit much for some .
I find some so called aerobatic types easier for even the raw recruit.
Thes models are quite neutral inall axis and if wing loading is quite low they are a piece of cake to learn with.
The Diablotin -the larger one is a good example
this model flies very slowly and yet has solid control resonse at almost walking speeds.
