I found that some original p3d files made by BIS can not too display properbly,Ok, so you've modified the main config.bin which isn't a good idea at all. You must create a small config.cpp file only for your model. Moreover, it means that you haven't made a config model for your model. And last, i think there is a main geometry lod problem with the model, which is very often the case if the model was a binarized model that you unbinarized with ODOL Explorer, because ODOLEX screws geometry.
The easiest way would be to upload your work somewhere and let us look inside.
such as radio.p3d.
i figure out the reason myself. it is because that i set the mass of the model
to 200kg.so the addon will sink down
