I'm finding that when telemetry is on for my FrSky RX6R the servos are pulsing, goes away with telemetry off. My assumption is this pulse is caused by the Rx powering up to transmit back to the Tx. Unfortunately in the tight fuselage of a glider the servo cable and shielded part of the Rx aerial have little choice but to be very near on another. Since I don't really have the option to move the Rx/wires in this model but I am wondering if some shielding could be employed on the servo wires. I assume others have encountered this - what was your cure?

Hi, This is a warning and a cry for help. I recently had a major crash with my Willow 1 due to a low battery. On. the second or third flight of the day I had a low receiver battery warning. I immediately gently nursed the Willow around into a landing circuit nicely positioned it and then I stupidly deployed the flaps , that sucked the last of the power out of the battery and it went in nose first. Checked the battery and it was indeed flat but cycled okay. I put it down to me not checking the charging properly. Yes I know I should have checked the charge before each flight. However after rebuilding both wing boxes I was resetting flap servos this afternoon when I noticed the v-tail servos were buzzing not the normal digital servo whine .The arms were not visibly moving and the linkages were not tight. While investigating I noticed that the buzzing varied with the position of the 2.4 antenna. Out of curiosity I checked the current draw of the model and was amazed to find that it was 600 to 800 Ma ! That explains the low battery. Further investigation showed:- Model only turned on 150ma Model and transmitter on, anywhere between 300 and 800 ma depending on the exact position of the antenna . The closer the antenna to the servos the higher the current draw. But there are not many options in a F3F fuz to reposition the antenna. If I shield the antenna with my hand current draw drops to 250ma and buzzing stops. Rebinding in non telemetry mode stops the problem. But I got this system for the telemetry! The transmitter is a Frsky X9E and the receiver a X8R bound in D16 mode.Servos jr DS3201 .Battery 1600 2/3 AA. nimh So any ideas to stop the interference? shield the servos , ferrite cores or what servos can I buy that do not interact?
