Roberts Bush Gear Conversion

 

The Roberts Bush Gear Conversion transforms the S-7S into an extremely capable bush plane.  Gone is the divergent tracking of the stock spring gear when operating on rough/challenging terrain, particularly with Alaskan Bushweel tires.  The Roberts gear is 3" longer than the stock gear, and fabricated from 4130 chro-moly steel, using the latest understanding of cub-style gear geometry, while weighing virtually the same as the stock gear.

​

Included are a specially made set of removable composite fairings that reduce drag, but allow removal in <10min to allow servicing and inspection.

​

The gear is a work of art, durable, and a must have for explorying the bush.
