i everybody,im now in progress to install all ribs in my vertical and rudder ..so all my vertical was done,but yesterday when i check to starting installation of rudder ribs .i found a little problem...on my construction book i have two plans ,one for speedster and the other is for model-4 1200...the problem is ....on speedster plan.they said to put a space of 2.32 at bottom and 1.52 at the top..but it"s impossible for me because the rod end at 2.32 is completly out of bushing....and on all plans he have 4 rod end and on my tail only 3....????
maybe because is early model...??

so for my tail the only solution i think is to trim all ribs on rudder maybe 1 inch +/-...

any suggest will be welcome...i dont think i happen only at me...???
