I would be interested in what methods some of you use for determining the proper place to cut pull-pull cable fuselage exit holes other than just eyeballing it. There has to be an easier way than some of the screwball things I have tried the couple of times I've needed to do it. thanks.

Take a piece of pull pull cable and pull it tight between the control horn and the side of the fuse where your rudder servo arm lines up. Mark a line on the fuse near the tail that follows the cable. Do the same thing but pull the cable tight above the fuse and eyeball where the cable will go through the fuse. Mark that location. That's about as close as you can get without laying the entire thing out in a 3D model in CAD.

SPLAIS-I usually draw it out on a piece of paper with length, horn width, distance, etc. all matching my set up.
Then I tape it to the bottom of the fuse and mark the exit points.
Next I use tape and make a line from the servo arm to the rudder horn on the out side of the plane.
Where the 2 points intersect you have the exit. Then widen the exit along the tape to your preference.

There's a reason the last thing you do when building a model is cover and paint it, y'know . . .

When you put all the controls and control systems in the model before it's covered, you can see directly where cables and such have to make their way through the skin.

I always locate a small balsa panel where control cables need to exit the fuse or wing, and support that panel with whatever scrap square stock is laying around. Makes it a lot easier to nail the covering down in the area of cable exits (antenna exits, too), and helps prevent the cables fraying the covering.

I make sure my servo arm and horn on the rudder are the same size - for example 3.00 inches. Now the cables have to be parallel and exactly 3.00 inches at the exit. I measure the width of the fuse with a caliper and find out where it is exactly 3.00 inches wide. Mark both sides with the edge of a piece of tape. Mark the height of the servo arm on the outside of the fuselage next to the rudder servo. Have someone hold a piece of string on the side of the fuse at this point and you hold the other end of the string on the rudder horn. Where this string intersects the piece of tape near the tail is the exit hole location.

I do it the same way Diablo does it. It's really hard to get wrong that way. A center line down the bottom of the fuselage will replace the caliper requirement.

If you have the full sized plans, you can lay it all out on the plans and then take the measurements from the plans and transfer to the fuse...

Diablo,Silver- Thats' a good easy way to do it. Next time I don't cross mine that is what I will do.

yep, I agree, thanks guys.
