Setting gear down for a model with retractable gear?

After much searching, I've decided to ask this question here:I'm trying to set the gear of an aircraft model with retractable gear (using as a replacement model for Squawkbox 3 traffic) down permanently, as I'd rather deal with that than planes that are floating about because SB3 doesn't do any handling of gear state. I'd even go so far as to write a bit of code if there was a FSUIPC interface I could write to or some sort of multiplayer DirectPlay magic I could do to force gear down of multiplayer aircraft, but it doesn't seem I can do that. I'm hoping there's something in the model configuration or aircraft.cfg I can tweak to get the desired result... any suggestions?
