Thanks, Tore, Your remarks are always welcome!
I don't think I will have the wintergarten decking removable, so the header tank will not be seen, nice to know it's there though.
I see the spark arrestor is a kind of trough cut into the hull, is that on both sides do you know?
I also have a question about dive planes.
below are the two options that I think I have seen around the net, the top one is reflected in the kit, but I've seen evidence that the bottom option where the planes are not connected at the tip to the wing might also be correct.
My preference is the kit version, but I've been putting off installing the dive planes because of this confusion!
