Good stuf this shute! I ordered one from John a while ago and I'm now in the stage of building it into my Avonds F16, needs some fiddling but will work it out. The shute really looks great and rigid. The F16 shute housing is kind of rectangle and it's width is smaller than the diameter of the supplied phenolic tube. May need alternative way of folding....

....hek, trouble shooting is the nice part of modelling....
