Compared with prior art, the present invention its remarkable advantage：
（1）It supports carbon fiber board as support member using two pieces of empennages, the weight of support construction is substantially reduced, compared with general
The support construction of six roots of sensation stock is reduced to two bars and two empennage support carbon fiber boards, reduces amount of parts, reduces
Difficulty of processing and cost.
（2）Compared with the support construction of general six roots of sensation stock, the rod piece of bottom is eliminated, reduces bottom rod piece under empennage
The obstruction of square air-flow increases the lower pressure of empennage.
（3）Empennage support carbon fiber board has slowed down the air velocity above empennage by its boundary layer, further increases
The lower pressure of empennage.
（4）Support two pieces of empennages support carbon fiber board of main wing parallel with empennage end plate, it is excessively curved or in crosswind in racing car
Under state, air can be dredged and flow to empennage, reduce the lower pressure loss, meanwhile, under the excessively curved state of racing car, positive direction is met
Wind can support empennage carbon fiber board to generate the component of a transverse direction, be equivalent to and provide more centripetal force to racing car, improve
The steering behaviour of racing car.
（5）Fin mills out airfoil by using PMI foams, the technique for being inserted into fin carbon fiber bar, compared with general
Hollow-core construction fin intensity substantially increases, simultaneously because the feature that PMI is light-weight and intensity is big, is processed using this technique
Fin can paste one layer of carbon fiber less, i.e., only need to paste one layer of carbon fiber altogether, this technique reduces the weight and cost of fin.
