Figure 8.  Fin positioning and orientation. The lead fins are positioned and toed in a manner consistent with the lead fins in most thruster-type set ups. The trailers are toed towards the same point as the lead fins and are placed closer to the rail than most modern quad set ups with a mind toward maximizing fin efficiency and small wave speed. Forward fins are canted at 7 degrees and rear fins are canted at 2 degrees per Mr. Sanders’ specifications.  Do not deviate from Master Sanders' specifications.
