Charley-

Tower Hobbies lists the prop nut size to be M5. It's the same as the OS LA .15.

I've used an acorn from the local hardware store that costs about 35 cents as a prop nut required by r.

How did you do in you're first combat session? Loads of fun I hope.

And how did the Magnum do for you? I've switched to OS LA .15's and like them alot.
