  • Such a cool engine and a beautiful sound. Is there any way to hook up an electric/ remote start for this?

    Is that an A-20 Havoc? It sounds soooooo sweet with the twin OS 7-cylinders!

  • @xKmotx Those puppies are mounted to the boss' A-20g Boston / Havoc. Definitely sounds magic. We should be taking some vision of it flying very soon.
