Re: 2007 Radio link reliability problem

We saw this problem occur last night with no load on the motors except the BB 56mm transmissions. We were running in the transmissions and testing the radios in one process. The battery voltage was monitored regularly and the lowest we saw was 12.1 vdc. Intermittently the motors would stop for just a fraction of a second with no variation in the input to the OI. We also saw the "Radio Modem" LED on the RC flash red at the same time the motors pulsed off and back on.
Bottom line: We will be contacting IFI today to report having the modem issue and wait for further directions from them on how to resolve the problem. In the mean time, we can use a tether or our 2006 modems to continue our build and testing.
