UAV-Grade Extreme Environment Control Rod Linkage/Push Rod Assembly
R/C Hobby control linkage and push rod assembly products were not designed for use in the extreme environments and altitudes required of today’s premium UAS/UAV platforms. In the early days of design however, R/C links were the only solutions available to UAV engineers and were initially installed in most small-to-medium sized unmanned products. Standard R/C hobby products have brass balls that must swivel within polymer rod eyes and do not cycle consistently in the extreme temperatures swings UAV’s must endure. The differing coefficient of thermal expansion between R/C-standard brass or nickel plated brass balls and the mating polymer rod eyes result in inconsistent fit as well as friction issues at altitude. The general quality of off the shelf hobby products have proven catastrophic when integrated into UAV platforms. After the loss of UAS/UAV platforms were traced back to R/C flap control and throttle control linkages, Battlefield International Inc. was contacted to pursue a design that would minimize/eliminate friction issues at extreme temperatures. Our UAV Control Rod Linkage is now the standard in the UAV industry and is integrated into most small to medium sized unmanned aircraft available today. The UAV Control Rod Linkage is a hybrid configuration that integrates strictly controlled R/C raw materials with Battlefield designed and produced critical components. Our approach has resulted in a fully tested and theater-proven solution that can be relied upon.
