You can fill in one or both of these fields. If you fill in both, the MotoWizard will consider only exactly that size propeller. If you fill in only one field, that measurement will be restricted but the other will not. For example, if you select Specific Size and select a diameter of 10 inches but leave the Pitch field blank, the MotoWizard can consider various 10 inch diameter propellers such as 10x5, 10x6, 10x7, and so on (this can be handy when you're trying to choose a propeller that looks right on a scale model).

Battery Options On the Battery options page, you can choose the type of batteries that you want the MotoWizard to consider, or specify exactly the battery you want to use.
To provide effective cover behind the defensive line, good full-backs are careful not to get caught out of position and must anticipate the opposition's play. Their position behind the backline allows them to see any holes in the defensive line and they either communicate with the backs to close the gaps up or cover the gaps themselves.  The full-back has the most potential for attacking the opposition, especially from a misdirected kick.  If a kick is fielded and there is enough space and support, the full-back may decide to counter-attack by running the ball back towards the opposition.  Due to their kicking skills, in some teams the full-back is also responsible for taking the goal kicks.
