I have a trumpeter kit and some left over airfix parts.........I was thinking about building IR Gleed's aircraft. I noticed 2 sets of wing tips for the clipped bird (one Trump and one from Airfix.......The Trump parts appear small and thin with nav lights and the airfix pair are much thinker with no nav lights. Both sets appear to attach to the wing in the same place. Which way to go? O' I was looking at the small filter bird.
