Almost everyone I speak to about getting my first plane qualifies the O.S. engine choice with, "Just make sure it's not the LA series."
Whenever you see an RTF or ARF model that comes with the radio, etc, the Engine is usually an LA.
What's wrong with the LA? Is whatever is bad about it so bad that you'd spend another $100+ to get another engine for the RTF model?
One guy said it was "mushy" but I have no idea what that means. Is this engine snobbery or a legitimate problem?
I can understand avoiding it (if there are problems with it) when buying just an engine, but is the engine so horrible that I have to pass on buying a model because it comes with one?
