“I use them in my F9F edf (Motion RC) and my P-51 Miss America (Tower Hobbies). They can stop a brown out - Its just a little added insurance to help me get back to the runway. My Spec 6 talks to me and manages my air time = Capacitor equals a little more peace of mind. Thanks for Asking”
“* Voltage ProtectorAfter installing the gyro, the servos will move more frequently than before, it is highlyrecommended that a reliable UBEC or ESC be used to provide sufficient working currentfor the servos on the plane, otherwise the gyro may become unstable by an occasionalvoltage drop. A large capacitor (3300uF/16V) can be used to get a more stable andsecure voltage level. You just need to simply plug it into any open slot of the gyro or thereceiver.”
