I am building a large scale aircraft and it will require 18″+ extensions. Do I need voltage suppressiors, noise suppressors, chokes or other items?
In general there is no need for noise suppressors in current generation Futaba equipment. Older equipment and some other brand’s current equipment do require this; however, Futaba does not. Twisting your servo extensions lightly and gently is a good idea, as it helps minimize the combination of the electrical fields from the 3 leads. Heavier gauge extensions are an excellent idea and are highly recommended, as much for the distance as for the high draw of high-torque, high-speed, ball bearing servos. If you see radio interference in your gasoline aircraft’s operation, look first to the gasoline engine’s installation. All ignition equipment, including an electronic kill switch, must be mounted at least 12″, and preferably 14″, away from all radio equipment, including throttle servos, etc. Ignition kill switch should always be on opposite side of fuselage from radio kill switch. All pushrods going to anything related to the engine must be non-conductive (just nonmetal clevises is not suf
