Does it cause any problems to have the leadout adjuster inside the tip too far? Some of my planes are 2" from the slider to the edge of the tip. Just wondering if I should try to minimize this somehow.

Thanks,

Mine are as much as 1 1/2" as my tips are swept back.  I kept the slider square with the C/L.  I don't think there is any problem.  I have never noticed any.  The plane in my Avatar goes from 1/4" at the front to 1 1/2 at the rear.

  The biggest thing you will notice on wings with "deep tips" and a lead out adjuster is that if you have a model that bangs the wing quite a bit you will see some marking and maybe even some grooving from the lead outs inside the slot if you make the slot too narrow. Not a big deal on a sport model but you may not like to see it on that 20 pointer that you just built.

I put teflon tape on the inside of the slot for just that reason.  However I still only got 16 points last time out.  Maybe the judge didn't like teflon. LL~

On the physics side of things, if you look at the Line II software* inputs you put in the semi-span dimension for calculating the line rake. Also the weight, expected flying speed, etc. So it does affect where the leadout goes. But since we invariably find the sweet spot by fine tuning (which is why you put in the adjustable guide in the first place) it's not like this effect would be noticeable.

On a deeply inset guide, I like to line the "tunnel" with 1/64" plywood. A wipe with thin CyA wouldn't hurt either.
