Glider Flying stab pulley mount

thingiverse

This is a compact cam-style pulley and mount designed specifically for flying stabs on VTPR RC gliders, including models like Le Fish, Vagabond, and DreamFlight Ahi. The cam works seamlessly with the servo to enable 90-degree rotation on these aircraft. To install, simply attach it directly to the stab without any screws, as it is a single piece. For the servo attachment, apply gentle pressure before securing it firmly in place using the screw provided. When working with pull-pull systems, an additional CAM mount pulley must be installed at a 90-degree angle to the original. In level flight, the servo pulley will be horizontal and the elevator pulley vertical on its longer side. This setup provides mechanical expo and offers precise control around neutral positions while delivering maximum throw at the extremes of movement. The 12g servo can be mounted directly onto the servo pulley without requiring any additional screws or bolts.
