Good information much appreciated. I have asked IVO for their recommendation. But your observation on weight and thickness is persuasive. Cost is a consideration but my experience with my earlier project convinced me to get it right FIRST. Will let you know what IVO tells me.
By the way, this forum is a great experience for me. My last project was 5 yrs and 6000 hrs with no on-line experience to consult. Flew it 18 yrs but took first 5 to get the engine perfected.
The kit fox will have to be my last entry in aviation. Hope to be flying before Sun n Fun in April.
