Clearly shown in this promo photo from the brochure airplane in 1965 when Helio Aircraft Corp. had its headquarters in Bedford, MA @ Hanscom Field. The idea of counter-rotating the props would have been advantageous in this respect to even greater single-engine control at low speed, also is evident the fixed airfoil between engine nacelles to alleviate airflow disturbance.
