Does the upper wing really have an inverse dihedral?

oh no no, I'm just playing and imagining this model! ... the upper wing goes without a dihedral, the lower wing has a positive dihedral Thumbs Up

by way of comparison between the Bi-Hawk and the Pitts ....

Okay, so I start locating the micro servos on the bottom wing.

By means of a teger needle and a round file, I generate the hole through which the power cables pass.

Centered upper flange aligned and glued central fiber rib.
The upper wing does not have a dihedral, it is totally straight.

Beautiful, Mauricio. If you glue the wing halves together, with the servos and their cables mounted permanently, how will you replace the occasionally defective servos in future?

Or, are the wing halves having the aileron servos not glued together for future servo replacement?

Or if you glue them together, do you leave a cable channel open and accessible for pulling the cables and connectors out through the channel for replacement?

I see the center struts are fixed in a trapezoid form to the fuselage. But, apart from the center rib to which the strut tops are bolted, will the top wing have any other support? Like additional struts between the tips of top and bottom wings, to keep them parallel?

thank you dear friend!
The micro servos can be removed, since I will make some holes as I show in the photo now, the previous photo is just for the purpose of seeing how the channel was made.
That hole or channel could have been made before plating with a raft, only I had not defined if I would place a single central servo for the four micro servos or as I decided to do then, that is, one micro servo every two ailerons.
in turn each micro servo will be covered with an acetate sheet (.05 mm plastic) with two screws, the micro servos are housed there with pressure, (they will not be glued), they will be kept in place thanks to the acetate cover that I will put there .... that's the idea.

Yes the model wears the upright. (MONTANTES)
In this case they are not only aesthetic but they are also part of the fundamental structure of the wing's stability and reinforcement.
The U / C cable channel will not be logically placed.

Placing linkage on the lower wing ... everything seems to be fine:

You sure are building a nice model.

No doubt that both are iconic schemes, Mauricio. Little Stinker with the checkers on the bottom always makes me jump at it. Art's S-1 was short lived and he got an S-2A soon after Skip Volk's death in his own S-1, but that red, white and blue scheme is recognizable on the Chipmunk and Pitts immediately!
You have a hard decision but either will be great.
