RE: Lanier or Midwest Cap 232??
Sorry Didn't know that lanier came out with a kit!!
I just went to laniers web site and read the building instructions for the kit. The wings are foam as is the tail. (This is not a negative or a positive just a note) The wing sheeting is 3/32 - overkill, but I have hear that lanier builds their kits so they will survive full throttle blenders!
I have built the midwest. All built up. Pretty light, especially if you take a dremel tool to the formers, etc that are overkill. loved the way mine flew.
Both have ABS plastic. I replaced mine with glass.
Good luck
Rob
