I built a RSM Jamison last year and now have finished it. I installed the bell crank per the plans. When I hooked up the elevator I noticed the up line was the front line not the rear as I am used to. I know why this is just didn't remember it being this way. Is there an advantage to this or was it designed this way for fit in the fusalage?

As Saprky said. 

I remember when Al Rabe first wrote about this.  His theory is that in certain parts of the pattern, the plane is in less than perfect conditions and the up line being in front would help maintain better control of the plane because it would have the most tension on it when it needed it.

Boy, that sounds confusing!    But he has his reasons that he spelled out.

I, too, have built planes both ways.  I guess I am not up to the caliber of flyer that would recognise the benefits.  Your milage may vary! 

Thru all these years I have had the up line in front and on some in back.  I myself have never noticed the difference as before the line sliders I would put guide as indicated on the plans.  Now I use line sliders and both lines are closer together.  Next is why have the up line on top with down line on the bottom of the vertical installations?  DOC Holliday

Leester!

Great looking plane!   I am willing to bet it will turn out to be a great flyer. 

Sparky: I thought it was great, it looks harder than it actually was. Once I do it a couple of more times the apperance will improve. Although it doesn't look bad even close up now it will get alot better.
