Apparently they do, Bill. Sending my friend the copy of the model that was backed up on my CF card didn't work. This is what gave him the error in the conversion program and why I posted my question to begin with. However, copying the model from the Internal to MemCard again produced a model on the CF card that DID import into the Model Converter. This is the crux of my question and open issue.

Assuming the model files actually are changed, then if an old model file was loaded into a transmitter with 1.6.2 software, would it have any trouble reading it in? Clearly the Model Converter has this problem, so I'm wondering about the transmitters too.
