jr8411 servos whistling
Dear modelers,
I hope that my email will find you all in good health.I have been flying models for almost 35 years,and because it is the first time that I am going to use digital jr 8411 servos,I would like your opinion,concerning a continuous whistling that they are making.When I switch them on,the whistling(sound like a used pot)starts and does not stop.When I go full throw,the whistling increases,and when in neutral,it does not stop.After 30 minutes playing around,on the ground,the whistling stopped only once,when in neutral,and came back again as soon as I touched the tx sticks.Because I do not know about digital,is this whistling normal?My flight controls are smooth like butter.Shall I return them back to the shop?Thanking you in advance,I hope to hear from you soon.HAPPY NEW YEAR ,full of good health,plenty of balsa and epoxy,and always with happy landings!!!!!!!!Best regards
