KISTEX,

This answer from the distributor is very useless! Not suitable? I don't believe that.

For all:
I discussed this problem with the most experienced pilot in our club (a guy who has build a couple of Extra's in different scales).
His anwser was that the CG shall absolutely not be more than 30% from the leading edge (in this case 123mm). For the first flight maybe little more nose heavy. Longer back and it will snap...[X(]
However I will try this with a CG 120 mm from the leading edge. If the weather allow it, I plan the first flight this weekend.[8D]
