I agree 100% with Bruce. Just like flying full scale, you need to get into the mindset that you are going to make an approach and a go-around. If the conditions are just right, you might land. There are very few times when an approach MUST end in a landing- dead stick, stuctural failure, engine not operating well enough to initiate a go-around, or anytime initiating a go-around might increase the risk of failure or crash.
