I don't know how much it weighs. I did have to add about 9 oz of nose weight to get the CG in the middle of the recommended range (despite putting the battery under the tank) - I'm guessing this is because it was originally designed for a .60. According to Tower Hobbies the wheels are 2.75", although I haven't confirmed this. It does sit a little nose-down, despite the nose gear being as far out as I can put it.
