Happy in-between-holidays all,

Not certain if this is the best place to ask about this problem, but because it affects a couple of my AI planes in FS9, thought it might be appropriate here.  I have a home-made design, as well as a freeware Cessna Citation, that share a similar problem.  When starting a flight, the wheels on both are at proper height relative to the surface.  Upon landing, all wheels on both aircraft appear to be half-sunken into the tarmac.  This is evident whether flying between airports or doing a touch-n-go, yet is not apparent when flying non-AI versions of the same aircraft.  Wondering if it might be related to gear suspension - I've tried playing around for the better part of a day to get around this (including removing any working suspension, and all manner of tweaking the contacts), to no avail.  Remaining AI aircraft display the proper "sit" at all times.  It's not a major problem but one of those that would be nice to find a work-around for if anyone knows how.
