Even though i have only limited knowledge of twin engine rc aircraft i do believe that counter rotating engines only help with counter the P-factor during take off and high thrust during slow climb. During an engine out it will make no difference which direction an engine is turning. If you go to the multi-engine forum they talk alot about adding outward thrust angles to the engines to counter the effects of an engine out problem. I have seen anywhere from 2 degrees up to 6 degrees recommended to counter the good engines thrust.
