Hi Manfred
Thank you for the kind comments.
I must admit that it does seems that the wing is on the heavy side. I think that modern CAD designed "super light construction" ARF aeroplanes spoiled us in recent years. There is a fair wing area to this aeroplane, so it should still be flying well.
I would love to see some photos of your wing and the changes you made (if you are happy to post it here). I am also wondering if you are going to build the vertical fin as designed or supplement it with Balsa construction (which is my intention)?
Cheers,
Eran
