Yeah, man, thanx. I thought about it so, but besides itīs a bipe the wing is not straight, its LE is swept back. So, the one third cord from LE (I think you meant one third, didnīt you?) would make a very fwd CG. Thatīs why Iīm asking if someone has some flying time in this plane and would suggest a CG. Thanx again!

I finished morback. is a super model. attached, who is interested in plans for cutting and CNC milling

Now I'm interested to know where your CG is exactly in this model. I have not flown yet. after the calculated CG-site should be between 90 and 96 mm from leading edge

I cut out all the plans and looking at making it with 3mm EPP foam seems a bit to week. What thickness of EPP did you use. Thanks

Aio 1,
F6Bert has posted a great set of plans for his Xtra 300. You may want to add them to the sticky. His plane is on my build list for sure.

Gernot Bruckman is one of the few who used an airfoil wing, ith his HEPF Yak.

Its hot wire cut from polystyrene block. Martin Muller used to use airfoil wings but says the best section for indoor aerobatics is the flat plate wing
