>>5378728I think the Disney Store diecast OT Y-Wing would do you nicely, it's about 5"-6" long:

I want to buy some for myself, but I've already got multiple versions of the vehicles from other toy lines so I'm waiting on a sale.
If you have a Disney Store locally, they'll probably have the Y-Wing on the shelves as I've always seen it at my local Disney Store.
