Folks,

Our rudder and elevator spars are built.  We are starting on the fin spars and have planed the spar caps to their double taper as per plan. 

We are having difficulty reconciling the width of the rear spar plan drawing with the rib widths on the loft diagram.  The widths of ribs #1,2,4,6, and 8 on the rear fin part of the loft diagram do not match up at all with the width of the rear spar drawing at the respective rib stations.  In fact, they are way off. The front spar drawing seems to be OK.

Has anyone noticed any discrepancies in the rear fin spar drawing??  My build team and I are quite perplexed by this.  Should we just modify the rear spar plan to match up with the rib widths shown on the loft diagram??

Many thanks for your help,
