Bellcranks for RC Control Linkages
A bellcrank pivots to change the direction of a control run or to split one input into two outputs, a common need in wings, control-line models, and older linkage layouts. This category collects nylon bellcranks in several sizes and angles.
Straight and Angled Types
Four Pi offers a 3 inch nylon bellcrank for longer travel as well as a 90 degree bellcrank for turning a control run around a corner, with a version supplied as two assemblies. The angle you need depends on how the linkage is routed.
Compact Sizes
For smaller models, Perfect large and small bellcranks and a 1/2A nylon bellcrank provide lighter options where space and weight are limited. Nylon keeps the parts light and free of corrosion. Selecting a bellcrank sized to the loads in your linkage helps it pivot smoothly without flexing under control input.
