I have noticed that some models have the engine and wing on a common centerline on the fuse while the horizontal stab is sometimes on that line or above that line in varying amounts. What are the advantages of having the stab in line or above the wing / engine center line.
Also what advantages are derived from having elevators and rudders with those counterfoil sections.

A good aerobatic setup can have variance on wing/stab power placement -
keeping em all reasonably close to a common line is a good idea but NOT mandatory
balance tabs? only if you just want to play with em.
it's all fun.
We could go on n on but the single most important goal?
keep the wing loadings down and make the control surfaces as light as practical and balance em as close as practical to hinge line
this eliminates possible flutter if done correctly .
