Shipping starts December 1st! 

Instruction Manual

Made in the USA. Each set includes two TailRails — one for each wingtip.

KBar TailRails are purpose-built for RC aircraft in the 40"–75" class (check fitment below). Weighing under 18 g in flight per side without battery, they keep your setup feather-light while delivering a serious punch of glow. Installation is easy: they bolt right into your existing SFG holes and stay fully compatible with Side Force Generators, so your CG and roll balance remain spot-on.

Balanced LED arrays, precision diffusers, and anti-shine caps work together to cut eye strain and spread light evenly. The result: a smooth, clean glow and a more comfortable, dialed-in night-flying experience.
