I'm NOT mixing anything up. You're mixing up marine and army helicopters, not me. You're making comparisons to army Hueys for absolutely NO reason.
The marines have used a variety of Hueys; both single and twin engine varieties. The UH-1N TWIN engine huey was first flown in 1969 and is still in service today. Explain why that makes it unsuitable for a 1985 mod? Do some reading mate.

Project 85 includes Marines. FACT.
In 1985 Marines flew UH-1N TWIN ENGINE Hueys. FACT.
There's an historical basis for including a Marine Huey in project 85. FACT.
It's upto Vilas to model whatever he wants. FACT.
