Hi Squiffy,could you explain how you fix the monofilament(I guess) to the ceiling/planes?
No problem! I take two roughly equal lengths and tie a loose simple knot in one end of each, then pass the knots over the spike of a drawing pin. Apply a blob of superglue to the knots, in order to ensure they don't slip, and repeat for the other end. Now we have two loops hanging from the drawing pin. The pin is pushed into the ceiling and into the loops is passed the aircraft, which usually hang by the fuselage. The Felixstowe being an exception due to the boat hull and being quite top-heavy, so this is suspended by the wings.
Although the monofilament is strong enough to take the weight of any of my models I always use 2 drawing pins for anything bigger than a 2-seater as the pins in the ceiling are the weakest link when it comes to weight. The R.VI has four pins and four loops - two around the fuselage and one for each wing.
