I have called DAX, got his answering machine.  He returned my calls promptly.  I was asking questions about his 4 stroke engine for my worksman trike.  I told him about Staton-INC.com.  and the engine & kit I could get from them.  He pulled up the site while I was talking to him.  He was very complimentary of their engine/kit  an recommended that I buy from them (Staton) since they had everything I needed.  I would definitely buy the Titan 2 stroke from DAX if and when I decide to purchase a 2 stroke.  He was very nice and willing to help.  He has responded to my emails promptly in the past.  I have no personal interest in this company.  He just seems like a good guy to work with.
