I broke and bent a few myself before noticing the error in my way. I can't believe I actually read the manual they gave us, although it could really use some additions to it.
BTW, when you get to mounting servos with gearing, don't waste your time trying to find the correct standoffs, its much easier to drill the holes out that get 1" standoffs, sand them down by an 1/8", put spacers to offset the servo, and then finally mount them, just drill four holes and you will feel much better after and save yourself a lot of time
