>> Anyway, my question is, I don't have a plane yet and am practicing on Real Flight G4 with my trainer, the Sig LT-40, and I see I can kill the engine with K key so should I be practicing landings with the engine killed alot or is it very uncommon for the engine to die while flying? I've been watching at local rc fields alot lately and have yet to see it happen. I plan on buying a OS Max AX 46 engine by the way. <<

Yes, you should practice them. Yes they are (should be) rare but they do happen. I never lost an engine flying full scale but could have handled it had it happened because practice engine out situations were part of my training.

As for RC, I practiced dead sticks often, with several different planes on the sim. After I soloed I also practice them at the field by pulling power at random places and altitudes. As a result my first REAL dead stick was no big deal; been there, done that.

Practice 'em.
