Thanks Dan! Yes the air-foiled struts for sure. I thought we got every option, to later find out kitfox has a hidden menu. The struts took soo much time to finish. Oratex was a huge time saver and weight saver. Was a little "alot" frustrated with it when it started to stain. Fortunately I was able to match some single stage polyurethane paint and paint where the exhaust was staining it. Corys is ready to go minus the out of balance spinner. Trying to decide what to do. It runs very smooth but now he put the spinner on it has some bad vibrations and this is with a balance mast on. May fly it without the spinner? We love the NR props but the spinnners, not so much.
