physbox arrows

I'm making arrows out of func_physbox entities and was wondering if there is anyway to make them first fly straight. I tried messing around with the origin but regardless when I throw it threw the air it stumbles end over end. I've made it so when you pick it up it points in the right direction but I can't get it to fly right.

2nd is there anyway to get the arrow to stick into a wall when it hits. I'm afraid the answer to this might be no as HLDM2 code stands right now. But I know you can get blades to stick...at least in SP. Was wondering if this would be possible, thanks for any help.

This behavior is not possible with func_physbox. Your best bet would be
to get a modeler to model an arrow and import it into Half-Life 2 as a
physics prop. The saw-blade sticking behavior is most likely compiled
directly into the model information itself.

Yeah that's what I'm up to now, not only do I need to tackle hammer but XSI as well. Phew.

try using phys_thruster or something thats all i know about a object moving...
