According to Falcon Linden's comment on PATHBUG-69 of 21 April this should remedy itself automagically the next time you rez one of the aircraft.
If it doesn't, the remedy is to convert the whole linkset from prim physics type prim to convex hull (on the features tab) and then to use edit linked parts to convert the sculpties you want to phantom to physics shape none.
I recommend doing it this way round because, if you leave any prims as prims, the LI risks going through the roof. But changes to the LI accounting system introduced to accommodate precisely this problem mean that, so long as everything's either convex hull or none, the LI should be no higher than it was before and may even be lower.
ETA If you simply need to convert all the child prims in the linkset that are sculpties to phantom, this should do the trick:
//converts whole linkset to convex hull and then converts all child sculpties to PHYSICS_SHAPE_NONE, effectively phantoming them
default
{
state_entry()
{
llSetLinkPrimitiveParamsFast(LINK_SET,[PRIM_PHYSICS_SHAPE_TYPE,PRIM_PHYSICS_SHAPE_CONVEX]);
integer max = llGetNumberOfPrims()+1;
while(max-->1){//don't try to convert the root to PHYSICS_SHAPE_NONE
if(llList2Integer(llGetLinkPrimitiveParams(max,[PRIM_TYPE]),0)== PRIM_TYPE_SCULPT){
llSetLinkPrimitiveParamsFast(max,[PRIM_PHYSICS_SHAPE_TYPE,PRIM_PHYSICS_SHAPE_NONE]);
}
}
llRemoveInventory(llGetScriptName());
}
} Just drop it in, and it will do the conversion and remove itself.
