i lost my propeller and im buying a new one but i cant find the white thing at the end can sombody help

GREAT MODEL AND REALISM IS SPOT ON. Very large as well. I love the moveable rudder, flaps and gear. This was my first COBI model and I am very impressed. Mainly construct LEGO sets but this is up to par if not better for is realistic appearance and detail. I don’t think you will be disappointed if you’re a fan of building block sets. I just finished the COBI TITANIC and am just as impressed. These sets are much cheaper as well when compared to other brands. OUTSTANDING!

Excellent product, the tank is meticulously reproduced. Cobi never disappoints
