Hi Richard,
I am building a SM MB339 in camo myself and this thread has been of great help - thanks! I did not like the standard pilots either so I went for the BBI Elite Force Aviator Pilots. They fit nicely and I think the size is correct.
Se link below. You can find them on ebay as well. You will not be dissapointed...
