looks VERY nice , good job so far
As for me I'm playing with many new ideas, I've already got my tail sorted, it slots into place so I can solar-film the tail and wing separate for a nice finish. I got some lovely transparent red solar-film for the job I can't wait to start covering.
To help with COG I'm going with one of my old designs where I mount servos at the top of the pod as far forward as possible, then the battery can slide underneth, this puts everything in front of COG. To adjust the battery can then move the entire length of the fuselage anywhere you want.
