Thanks for the advice guys, I have set flapperons on a switch for about 7mm, I also am able to adjust the trow using the respective trimmer. So I can have a play at high altitude.

I have just finished assembly of the bird, dry flight weight ended up quite heavy 9.1 lb / 4120g, the manufacturers specs state the fly weight to be 8.2 lb / 3720g.


elenasgrumpy, any idea what weight your friends bird ended up ?
