It is overly complicated.
A simple vee-tail with the autopilot commands mixed with the radio commands will work in a less parts intensive and failure prone manner.
The fewer parts the lower the chance of failiure.
Longitudinal stability, apparently your main concern, is a product of the areas of the wing and tail, and the center of gravity. It can be built in to such an extent the autopilot's task is reduced to an attitude hold condition. The airplane will do the work.
Adjusting the servos for the tails to provide the differential can be done with the control system geometry in the plane, or at the transmitter.
In addition, combining the extraneous surfaces into two will reduce the induced and parasitic drag of the multiple surfaces you have.. two fewer tips, and a much reduced interference at the fuselage junction.
And, white on top at least, for composite construction.. Black is a heat sucker, and can create bulges and delaminations in the layup.
