aerodynamic effect of lower intersection fairings

[KayS]

Hi All, my 7 now flies for 4 years. gear leg fairings, upper intersection fairings and wheel pants are installed but i never found the time to install the lower intersection fairings that attach to the wheel pants. so it's time to attack those. are the lower intersection fairings somehow critical when it comes to unwanted yaw/roll input? do they have to be super alligned with the similar measuring exercise as we do usually for the gear leg fairings? i found out the hard way that the gear leg fairings can have an significant impact on yaw and the lower fairings are attached to them.
