If they do the hinging the same on the sav for the fin and rudder my advice is to fit the rudder to the fin BEFOR you put it on...its a nightmare if you dont...you need 15 fingers and 3 tongues to hold while you are trying to do it. That way you only struggle with the bottom hinge while on the ground not standing a on a step ladder

 

 

One of the ways that the 701 differs from the Sav is that the rudder is all-flying.  Hinged on 2 bolts at the rear of the fuse.  The "fin" is simply the extended strake at the top of the fuse.

Put the rudder back on and got onto the rudder cables next.  Had to enlarge the fuselage slots substantially, not sure why the plans show them so small - would have rubbed the cable to buggery.

 

Just if you need Marty, not saying you do, but info for others as well, run the cables through fixed small diameter copper tube where rubbing might be an issue.

Probably would have been a good idea - there's a nylon fairlead on the outside skin with a formed half-cone fairing over where the rudder comes out.   Works ok now.

Finally got the rudder cables tensioned up and hooked up to the pedals.  On the first attempt I wasn't getting full authority so moved the pedals back 10mm, re-tensioned (different holes in the 0.040" plates) and it's now getting to the stops on either side.

 

Today I deburred and filed all the fin pieces, primed the edges and riveted it all on.  Looks a lot better with those bits done!  Also adjusted the rudder cable slots again, ended up riveting a bit of nylon INSIDE the fuse on either side too.   That was interesting trying to reach everything through that hole at the top of the fuse, which is only just big enough for my arm going in and scraped the hell out of it going out.

Also had to come up with an innovative solution to file the fin rivet holes at the top of the fuse - couldn't reach the inside either from the back hole or the bottom hatch.  Ended up cutting a long dowel on an angle and attaching a file to it using electrical tape.  It worked!
