adj lead outs
« on: February 01, 2017, 09:58:27 AM »

  I have all my models set up with a slider type l/o  adjustment, and the l/o's are 3/4" apart.
 What sort of set up do you have/use?   Thanks

The top guys use individual sliders or holes & movable grommets, because they're good.

I use individual sliders now, because Paul Walker told me to, and when you live in the PNW, when Paul talks you just say "yessir!" and do it.

The problem with electric is that once you get the smoke generator and sound system installed, the plane is too heavy.

Are you asking about type(s) of adj LO-- OR ---what is preferred spacing between the two lines?

All my planes have some form of Adj LO. But my line spacing is set by what I see on the plan or an imitation of what I see in some model photos

I fly sport only, so not very critical to me IMO, but still curious about any Rule Of Thumb relating to the correct spacing

The correct spacing between the lines is whatever it takes to trim the airplane to fly the way you want it to fly.

For that reason it's probably always best to use individual adjustments on each lead out, However for sport flying a single slider works OK with the lines spaced about 1/2 to 3/4 inch apart.  If you use 1/2 inch it's probably best to make sure that the connections to the lines are snag free.  A lot of guys stagger the connections by using one lead out longer than the other and two different lengths of lines.  If you ever have your lines snag during a maneuver you will too!   Or if you use a cable handle simply adjust the handle to compensate for the stagger.   That's not to say I ever recommend cable handles...I don't!!  They add springiness into the control system which is intolerable for most people if you want to be precise!  A lot of sport flyers use them for convenience and if that makes them happy that's fine.  If you want to compete use a hard point handle.Most of the top stunt fliers use them for a reason!

I would never recommend using the line spacing, without adjustments, shown on the plans.  Chances are the draftsman that did the plans just stuck them in a convenient place and not the correct one.  Every airplane is at least a LITTLE different, and there is no magic in where to locate the lines...sounds silly but..."They need to be where they need to be!!!".  The only way to get them there is to fly the airplane and adjust them until they are correct!  

There is a program available that will give you a good starting point called LINE II.  Or you can simply start with the center between the two lines at about 5/8 inch behind the CG.  That will give you a safe starting point to adjust from.

I usually start with the rear leadout going perpendicular to the fuselage and then put the front leadout about and 1.25 inches in front of it. Amazing  how many times that turns out to be darned closed to optimum for me.

Guess you already did a search on here?  I got the following off of a search on Stuka Stunt.  There is also a construction series I couldn't find.  If you want to spend time reading you can do a search over there.
