Turnigy RM-91 servo and circular horn
grabcad
Unable to locate any servo prototypes compatible with RM-91's peculiar shape. Thus, a preliminary model was constructed for testing purposes. This model may benefit others due to the affordable price of RM-91 despite its specifications. The servo is accompanied by a swiftly designed circular horn; outer holes are suitable for M2.5 screws and bolts (or potentially M3 threads). Center hole accommodates the RM-91's rotor bolt. Printing this horn requires a 3D printer, with optimal position being flattest side downwards (successfully printed on Replicator 2). Despite performing exceptionally in assemblies, any detected errors should be reported, as dimensions were measured manually using calipers which could lead to possible inaccuracies.
