Spektrum module “Shut down” issue -

Service Announcement for Spektrum Module Users Simple fix for module “Shut down” issue A few of our customers are experiencing a “shut down” condition with their Spektrum module systems. A “shut down” can occur in a hard crash, or while running in a specific area of the track. It is characterized by a loss of power to the servos. To reactivate the system, it is necessary to turn the receiver off, and then back on again to resume normal operation. Shut downs are most prevalent when racing on carpet due to static electricity, however they can also occur on any surface during a hard crash. This issue is not a related to DSM technology, but is a result of an improperly routed antenna inside the module, which causes a compromised link quality. If you’ve experienced a “shut down”, please return your module to Spektrum’s service center for quick repair, which involves installing a new, longer internal antenna wire with the correct routing. While this issue affects relatively few modules, you can easily check your module to determine if your system has the proper routing - refer to the instructions below. We apologize for this inconvenience. We are committed to achieving perfect reliability and your total satisfaction with Spektrum products. HOW TO CHECK YOUR MODULE Using a Phillips screwdriver carefully remove the case from your module and examine the antenna connection to the board: Correct Note the antenna coax is routed under the main radio board. Incorrect The antenna coax is routed over the board in close proximity to power capacitors and IC’s compromising signal integrity. Please return to Spektrum for service. In the case of Futaba Hitec modules, a longer antenna wire will be needed. Copyright © 2005 Horizon Hobby. All rights reserved.

Chip at Al's has resoldered both Lance's and my antennas back to the board. I couldn't even see where mine had ever been attached. A hard hit will cause the poor solder connection to break free some times.

Well, I sent mine back last week. Having the exact problem stated.
Hopefully I will have it back soon. As long as you still have the receipt, they will fix it no questions ask. This is my 2nd sent back for repair.

when my antenna ripped off, I sent it in. Took them a week after they received it to "check it in", then a month after sending it for me to get it back in my hands. Click Here!

no. I bought a second receiver in case I ever have to do that again though. They don't send you back your receiver, they send you back a refurbished one. You will have to rebind it. Click Here!

Now I know why my Mayhem crashed the 1st time....
Does anybody have pics of the "revised" spektrum receiver? It looks like you could take the antenna and insert it through the board from the OTHER side, that way it will not near the caps and ICs. Here's pics of mine. Is it the 'bad' one?

really? I sent all my Rx's to them twice now and both times I got the same ones back. I know this for sure because I put velcro on the back and black marker on the front to mark the negative wire location on the Plugs. Both times I sent mine though were for software issues though and not anyhitng physically broken. 1:1.. 01 Z28 Camaro A4 Sure.. its stock. 1:8's.. K3, Inferno GT, and a straight line beater car 1:18.. RC18t Mamba and 3s lipo |
