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.
