Guys I have problem with my 707-300...
I have established on cruising altitude and autopilot was set to hold 30000ft, but soon after I have done that my plane has started to bounce. It has started to climb aprox. 500ft above fl300 than it started to descent to 500ft below fl300 that "circulus viciosus" continued during my entire flight.
Anyway I can't make my 707 to continue with stable flight without those variations in altitude.
Am I doing something wrong or flight dynamics are incorrect???

This problem (experienced by "some" users and by no means all) was completely resolved late last year .... so far as I/we've been able to establish to date.
After a few (very few similar reports) and a long and exasperating period of examination this "porpoising" issue (during AP controlled high altitude cruise .... with ALT HLD selected "ON") was finally traced to the way DIRECT X interacted with the original AP programming. For this reason the AP was reprogrammed and new B707 GAUGES/CORE FILES uploaded last December.
This I can state this definitively .... because I (myself) went through an initial 3 years of faullessly perfect AP controlled flight/cruise stability .... to a sudden and unexplained (at the time) instability for a couple of months late last year .... which occured only after uninstalling some other then redundant non-FS related programs which likely bumped DIRECT X also. Unfortunately I can't be too specific regarding these details now because I'm overseas for the next few months and right away from all my original FS notes/observations. Since replacing whatever original DIRECT X version I was using at the time of my disruption ..... along with the said AP gauge reprogramming too .... neither me .... nor the only other user I know of whom was similarly affected over a very much longer period than me, have experienced any further AP controlled flight/cruise stability problems
You must ensure that you have both the current B707 GAUGES/CORE FILES and Panel version installed .... and from this website only.
PLEASE NOTE .... we can't/won't/don't vouch for anything obtained from elsewhere.
The "last modified" gauges dates for each of the 3 B707 panels gauges files you currently have installed should read as follows
707-120.gau = Friday, December 5th 2008, 01:29:52 a.m.
707-320.gau = Friday, December 5th 2008, 01:29:42 a.m.
707-LATE.gau = Friday, December 5th 2008, 01:30:02 a.m.
If you have these gauges (last modified dates/times) then there's no reason why you should be experiencing any problems at all .... and I would then suggest that you need to focus on your AP ALT HLD engagement technique.

TNX for your reply. But I'm using the original panel with original gauges.  |

"THAT" (along with possibly the same DIRECT X issue which both myself and a few others encountered) is likely why you're experiencing this problem .... if you're still using the original/older panel/gauge data !
You "MUST/SHOULD" replace all your original GAUGES/CORE FILES package with the version currently downloadable from this/our website.
I recommend that you replace all your current original B707/720 panels, and aircraft base packs with those same versions currently downloadable from this website .... just to be sure of overall compatibility of everything.
In other words you're looking at replacing "EVERYTHING" you originally had .... with the exception of your aircraft textures.
