I am going to take mine back to Hobby Zone and let them listen to it. No way the high pitch noise is the motor. Ihave it whether the motor is on or off.

Please keep in mind that this aircraft uses digital servos and it is normal for them to emit a sound when powered on. This is normal.</span></p><p class="MsoNormal"><span style="font-size: 10pt;"></span></p><p class="MsoNormal"><span style="font-size: 10pt;">If you should need further assistance regarding this issue please reply to this e-mail for additional support.</span></p><p class="MsoNormal"><span style="font-size: 10pt;"></span></p><p class="MsoNormal"><span style="font-size: 10pt;">If you need assistance in the future, please feel free to e-mail us at productsupport@horizonhobby.<wbr></wbr>com or you may also contact us toll-free at 1-877-504-0233.

I get a continuous tone coming from the receiver after I operate any controls on the transmitter. All controls operate properly. Is this normal? The tone is not like the whir of the servos. I have done all checks including re-binding the receiver. Thanks for your help.

It does not seem to be causing an issue so we would not think it should be a problem.</span></p><p class="MsoNormal"></p><p class="MsoNormal"><span style="font-size: 10pt;"></span></p><p class="MsoNormal"><span style="font-size: 10pt;">If you should need further assistance regarding this issue please reply to this e-mail for additional support.
