Checking the props would be one thing to add to my pre-flight check. I'm not looking for speed of trying to get in the air, I'm looking for ease of transporting more than one item. Sometimes when I go out of town I take one or both of my r/c trucks and my balance charger. A bigger case means less case to carry as I will be able to put two remotes and the balance charger in one case. Plus we usually do some target shooting so having to only carry two big cases instead of four cases makes a lot of since and takes up less room.
