The vertical stabilizer is to provide additional anti torque force to the fuselage once the aircraft has forward motion and airflow across the lifting surface. The design makes use of forward motion and the resulting airflow to create an anti torq...
The amount of the alkoxyalkylnitrile stabilizer which is required to stabilize perchloroethylene is exceedingly small, about 0.01 to 0.1 per cent by weight of alkoxyalkylnitrile being desirable to obtain optimum results. However, larger amounts up to approximately 1 to 2 per cent are eflectivc and may be employed if economically feasible.
