Unfortunately from what I have read and researched, I don't think the 100's are going to work. I know there are guys who have used VT80's and had an excessive amount of nose weight needed. I know he is concerned about the CG and is trying to move things forward but there's not a lot of options in that airframe! I have only seen pictures of the build and not seen it in person as he is in Texas and I'm in California. I know many people are flying them just fine on K60's
