JollyPepper, if you need small pulley and hardware, check out Proctor Enterprises. I have found that nylon guide tubes work as well for less than 90 degree turns so have never used pulleys on any of my later builds. The only time I did was on the ailerons on a 1/4 scale cub but found that the wing flexed enough under high G manuevers that the cable tended to jump off the pulleys.
