My 1st MS went bad for no reason a few weeks ago. I emailed Hobbico customer service thru the MS site about the prob and they sent me a complete chassis minus the body. Their CS is awesome! All I had to do was fill out the CS survey and they told me a replacement chassis was in the mail. Too bad the only freq that MS and Bits share is 27mhz. All you need is the FCC # off a MS, and if you've got a bad 27mhz Bit then you will be up and running again in a couple of weeks. I'm sure someone has already thought of this. Once again Hobbico CS rules!
