Hi there!

To your questions:
1. All the systems "should" work on the 707 for FSX. Some of them got bugs which have to be fixed and most of the bugs we've found so far are on the list for the next update. Look at my unofficial bug-list here:

For example the elecric system works very well!


2. Theyre not locked, but theyre movement is limited. They move, but just a little.

3. The EPR gauges in the FS9 version were totally incorrect. But as far is I can tell, the EPR gauges in the FSX 707 work very well, e.g if you set the throttles to 1.80 EPR, they barely move up to cruising-level.


Altogether the FSX 707 is a great bird, altough there are a lot of minor bugs which have to be addressed. But the first update isnt too far away.
