10x with Spektrum Module
I have a 10x that I just purchased the DM9 Spektrum module with the AR7000 reciever for. One odd thing I have noticed is a buzzing sound coming from the radio beeper with the 2.4 module. It does not buzz with the 72mhz module. Is this normal and if so what is causing that?

RE: 10x with Spektrum Module
Most likely it is the voltage regulator circuit and should be of no concern. A number of people have commented that their X9303 buzzes. 2.4GHz being of much higher frequency can send all the info that is needed in a short burst. I’ve read that it is broadcasting less than 20% of the time. It is the on-off of the rf being broadcasted that causes the regulator to buzz. My 12XMV buzzes with the 2.4GHZ module but not with the 72MHz module. Maybe due to my age, I can barely hear it when I hold the transmitter next to my ear. If your transmitter is making too much noise, you should contact Horizon. It's possible some components are physically moving and that's not good.</p>
