AirWild Uni-Arm is a double-truss, right angle (90 degrees) servo arm designed specifically for rudder pull-pull application where multiple servos are placed side-by-side and ganged for extra output.
The unit consists of two laser cut L-shape output arms made from 6061-T6 aluminum. When coupled to an AirWild Uni-Hub (available separately) the combined assembly creates an extremely rigid servo arm structure. No more worry for spline stripping as often found in many nylon wheel based double-truss servo arms or single-plate phenolic arms.
AirWild Uni-Arm 90-Degree package consists of;
Aluminum 90-Degree Arm (2)
Socket Head Cap Screws, #2-56x3/8 in. (4)
Hex Nuts, #2-56 (4)
Geometrically and functionally Uni-Arm has a "coupling side" and an "output side". As illustrated by the outline image the short 1 in. arm is the "coupling side" which is linked to a peer servo for ganging of output torque. On the 1.25 in.-long "output side" which is at 90 degrees to the coupling arm, Uni-Arm offers two hook-up points allowing user to optimize rudder pull-pull setup for his particular scenario:
1.00 in. - Maximum Torque Transfer
1.25 in. - Increasing Throw
We recommend Rocket City 1/4 HD Ball Links (ROC87), Rocket City 1/4 Extra HD Ball Links (ROC57), Dubro 4-40 Heavy Duty Ball Links (DUB 899) or other comparable ball links for use with Uni-Arm
