Looks like the gunner really needs to get into the turret from the top of the vehicle, or maybe I missed something, correct me please if I'm wrong.

Ok, thanks I will remember that, so wheel well in filipino is 'balon ng gulong'? he he he :-)
No. I'm not shifting to a/c, armors will always be my first love. I'm trying to learn a/cs para may variety naman sa hobby ko, and I learned a/c is like a different animal to handle.

In the future try ko naman ang ships inggit ako sa carrier ni Mang Ernie eh :-)
Guys,
Thank you all for the info/support you gave me regarding this projects. All in all I have all the references I need, many many thanks.
Good day!
