Oh yeah Alex, if you have any more money laying around you should consider the Tower Hobbies muffler. It's $13 shipped. The Will give you about 1000 RPM on your O.S. .46 and really make that thing a rocket going straight up.

I used an 11.5x4 on my Pro .46 and it was just perfect...

The Dubro landing gear is a must, and the muffler is a really great upgrade. I say the landing gear is so important because the stock stuff will keep bending no matter how soft you land and eventually break, most likely breaking the fuselage off with it.

Now you got me missing my Extra Special more than I did before!
