I got prop guards and I ordered a 10 dollar Black and Decker power screwdriver, which fits perfectly inside the X-Star case. I keep the bit on it so it won't get lost. It takes just a few seconds to take the two bolts off each motor housing then attach the guards. They weigh very little and probably reduce flying time a bit, but I have an extra battery so that doesn't bother me. I want to get used to them, and I would rather have my drone fly into something with a dull, somewhat flexible piece of thin plastic than with a high speed sharp edge. There have been accidents from propellers cutting into skin and eyeballs and stuff. It's up to each pilot to consider how he wants to handle his risks.
