ive never had a problem with LOC tubes. great for building rockets

LOC tubes are straight and havegood build quality (seem to be a bit stronger than their Estes counterparts). Perfect for use as a main body tube and makes for an impressive sized rocket when you couple 2 together. The 2.6 tube will fit 3 D engines clustered together for a very exciting rocket launch. White spiral outer casing does leave spiral groves that show through paint if not lightly filled and sanded. Overall great tubes.
