So, I went with slightly smaller fins and took a few inches off the nose to correct the over-stability issues. The winds were a bit high; 7mph or so sustained and gusting to roughly 15mph. This resulted in more weather-cocking (though not quite as bad as last time), and ultimately the loss of the air frame. We searched some, but it went in the woods relatively close to a nearby archery range. We decided to just chock it up as a loss. I've already got V2 in the works, so look more updates soon!
