Only one flight did we shut down the engine with the carb before the fuel tank was empty... otherwise, EVERY landing of my Dust(s) have been deadsticks. We haven't found it to be a problem, because it does give you some warning that its about to run out. You will be doing a turn or some other medium-G maneuver and you will hear the engine bobble from sucking air. Then you know you have 10-20 seconds before the engine quits. That's normally plenty of time to get setup for a landing. 10 seconds is a long time with a 175mph+ model.
