The propeller shaft bearing is of metal and is lashed to the cross-piece, called the base, Fig. 231. It is not necessary to have two points of bearing for the shaft. The metal is about 116″×14″×1″, bent as in Fig. 232, and lashed to the under side of the base. The planes are similar to those in the next model. 1″× 112″×712″ propeller blanks are used. Try about fourteen strands of 116" string rubber for each motor, seven rounds.
