Bi-directional Prop Graupner 8 x 4.5

A so called "4D" prop - works the same with both turning directions. Requires the correct ESC, capable of bi-directional operation - e.g. the Volta Reve 18A. Ideally use 2206 size motor, like the Volta X2206/1400 and 3s battery. 2204 sized motor is probably too weak for this prop.
