we use the 507ETTL. Perfomrance is good.
There seems to be a problem with the configuration to be saved permanently in 
the module, but it does not occur after each power cycle. Only if the module is 
not powered up for some weeks it needs the reprogram. 
I think it will be quite some work to implement the setup in the autopilot 
code. It needs checks after each step and changes in the baud rate...
I think it is a problem with the gold cap on the board being too small. Perhaps 
an exchange with a bigger one could solve the problem.

Are you sure about the 5V power supply. Ours run with 3,3V.
