Do the alternators have an internal regulator? Do they have overvoltage protection (such as crowbar overvoltage protection)? Are the regulators switching or linear? Is it possible to get the engine with the alternator attachment hardware but without the alternators?
MISTRAL engines are designed to meet the structural requirements for utility category certification (+4.4G / -1.76G). The engines are not equipped with an oil recovery system for inverted flight.
