Originally created for the R2 Hobbies Passer X series of gliders, but also applicable to many other sailplanes with Top-Mounted V-tails of the same angle. This clamp was designed to make fixed V-Tails removable and completely separated into 3 main parts (Left & Right Tails + Clamp) for ease of transport. 2x plastic 3mm bolts and matching metal/plastic nuts will be needed for completion.
