Basic rules of flying a twin on a dead engine are based on maximizing control with asymmetric thrust.
Bob Hoover was well known for showing people what could be done, well past the normal when flying twins on a single engine.
There is one story where he was doing an FAA check-flight to keep his airshow rating and ran through most of his airshow aerobatic routine (though at a bit higher than normal altitude for some of it) and got a pass, (pass or fail, no other grades) then told the FAA representative that during the single engine portion the operating engine was running poorly and only had about 60% of normal power.
If you can maintain adequate airspeed for rudder authority to overcome the asymetric thrust trying to yaw the aircraft, then you're fine doing anything the aircraft has the power and structural capability to perform.
Some designs do better than others and altitude can allow you to get away with a lot due to having room to recover.
Models often have LESS ability than the full scale to successfully do single-engine-out operations due to the model's higher power to weight plus inability to feather the dead engine's prop resulting in NEVER having enough rudder authority.
