High folks, I did a search but could not find a reference to what line length I should use on my Challenger15. Thanks--Louie

 Challenger .15? Is yours the Keith Sandberg design? If so, Keith, Rachel, and everyone up here has been using .012 x 50-52' lines on them. Most have had bone stock LA.15's with Master Airscrew 8x4 props, it's been a perfect combination.
