TBS Caipirinha

The TBS Caipirinha is a small wing released by Team BlackSheep purposely designed for FPV use. It can be flown anywhere and the light weight makes it resilient to crashes. The airframe has pod inserts in the front for a GoPro HD camera, in addition to a pod to make it easy and safe to mount a FPV camera.

This is a great wing to get into FPV or to learn new tricks for proficient FPV flyers.

Tips and tricks

• When choosing folding props, Aeronaut assume a 42mm yoke centrepiece, whereas Graupner assume a 32mm centrepiece [2]
• Minimum 1:2 static thrust to weight for leisurely flight, 1:1 for aerobatics, and atleast 1.4:1 for extreme maneuvers [3]
• A thrust-to-weight ratio 1:1 means that the motor generates the same thrust as the weight of the plane [4]
• Use 3M double-sided tape to fasten servos and packing tape to cover the compartment, easy to remove for later repairs and upgrades
