Radio - JR & Spektrum DSM > DX7 Spektrum 6100 receiver lost bind.

I'm looking for some troubleshooting assistance.

Background - Mini Titan with Thunder Tiger speed control, Spektrum 6100 receiver. It was bound and flown numerous times.

Problem - I plugged in the battery, the gyro blinked but speed control did not do it's chirping nor did the receiver light. I was puzzled by the fact the gyro kept blinking rather than the normal steady light. I tried the controls and nothing functioned. I thought about this for a while and checked that I was as low throttle, proper model memory, normal mode, throttle hold off. Nothing.

Next I tried to rebind since it acted like a receiver that was not bound to the model. Everything was fine after that.

Question - Why did this happen? I'm thinking about two things, one that I changed something on the transmitter that made the receiver think this was a different model. Two, that the receiver lost its BIND somehow. I appreciate any and all thoughts on what I may have done wrong or what might be amiss with my system.

Bit of a long shot..But..

I know it's not a leccy model On my Raptor I have switched to a pin flag switch that is is easily bumped causing the onboard R/C to get a pulse if accidently touched.

This in turn seems to cause my Revmax to loose it's stored parameters requiring re-calibration.

With the electric models there is often a pulse when connecting the batteries up..would this be enough on occasion for it to loose the binding? As it seems most problems are with electric models.

Perhaps you simply had the bind button pressed (something contacting the bind button or the way you were holding the TX) during the TX power up? If that happens, the DX7 will not get the DSM2 ACK handshake from the 6100 (bind plug not present, RX in run mode) and will assume DSM (ala AR6000) - this would necessitate a rebind.

See this thread on RCG and the follow up replies for more detailed info.
