I don't know about breaking one in, but as for the power issue you have heard correctly. The LA series is weak, but if you do not need much speed, torque, or feel the urge to fly 3D, then it is a good affordable choice. The FX series by OS are a lot more powerful than the LA series, but the only downside is that they are more expensive. The FX series is also easy to break in, or at least in my experience they have been.
