No new file for Fortec ultra as of Aug 17 2006.
The reasoning behind this is the memory on the fortec ultra and other models is only 1 mb. The newer receivers have 40mb or more of space. So when a fix needs to be made for a receiver its much easier to write them when you have lots of space to store the new bin file.
Menus also have to be stripped out to free up space.
I hope this makes sense.
