I just measured my CG and it is 25mm in front of the wing tube, well ahead of others which is strange. I like a very neutral flying plane so although my cg is well in front of others, I find it to fly very well this way. I may want to move it back a very small amount, but it's very close. I'm still waiting on a calm day to refine the trimming, but so far the only mix I have is a 3% down line mix and only a small amount of down elevator is needed when inverted on 45s.
