I fly with a Futaba 9C. Recently, I had a module fail, leading to intermittent lock-ups when flying, but I was able to successfully land my airplane. I had had a few glitches previously, but I thought that that was due to mechanical noise. I did some tests and was sure that the module was to blame. I replaced the module with a synthesized module and have had success.

I fly on a flight sim a lot, and plug in my transmitter to the interface cable. The transmitter turns on just like as if it were a buddy box, not transmitting. I never took the module out, as I never knew there was a reason to. I was told that this is what killed my module. Should I be removing my module when using the sim? The transmitter, as I understand it, is in the same situation when on the sim as when being used as a buddy box. So why doesn't the manual say to remove the module when using the transmitter as a buddy box? It's not transmitting, so where would the harmful RF energy be coming from? Is it bad for the transmitter to be on without a module plugged in?

Thanks in advance.

I have the same setup so I would like to know as well. Thanks

With a buddy box, the entire transmitter isn't on, only the parts needed to convert the sticks to the pulse information.

With a flight simulator, the TX is on. With the antenna down for extended periods of time, the transmitter module can get overheated.

I've used my 5UAP with the simulator with the module removed for quite some time now, I think removing it is the best way to go.

Do you also leave your antenna extended 1 length as suggested?

Remove the module.

Simple enough. Thanks Bill.
