I just finished mine. Flying it on 5S 5000 packs with the same setup as Joe L. Flies pretty well despite the excessive up elevator trim required.
The trim in the pictures is for level flight with the CG right at 145 mm back from the leading edge (front of wing tube) and even a little behind that. I have never had a plane require this much elevator trim. It is not a thrust issue as there is no real change in attitude from full throttle to idle. I measured the incidences using an aeroperfect meter and found the stab to be 1.4 degrees positive compared to the wing. I doubt that is what the manufacturer planned. Has anyone else experienced this issue.
Thanks,
Stuart
