Centre pieces specially designed for the Travelauer Turbo Spinner series in all conceivable gradations. A perfect spinner-blade pick-up solution for every application! In addition, you can mount rubbers (B. Nr. 73055-73059) which significantly improves the fast folding of the propeller blades. "Offset"- version for even more perfect attachment of many propeller blades to the fuselage. Info: To adapt to the Prop: Please enlarge the cut-outs a little bit (usually only 1-sided - approx. 4-6mm) If a knife or lexan scissors are used instead of the Dremel - please warm the cap first (to avoid jumping).
