I think the landing gear is going to be fine. It seems more robust than my Habu 32 with tams struts. I wish I would have weighed the habu, it felt a lot heavier than this plane.
My apologies for not seeing this through maiden. The e-brake controller I had was bad, and another one is coming from singapore. I'm knee deep in moving into a new house right now and planes can't be a priority. Hope to maiden in August. I know someone else above has already flown their K45 powered Avanti and sounds like it went well.
