I wonder if it would be twice as good or overkill if you were "OCD" and plugged two of these bad boys into spare ports? But I think for the price its at least worth the added protection. Like some of you have already stated a random high draw of a servo could be just enough to allow the voltage to dip and cause the receiver to reboot, so that's where the stored power in the capacitor would kick in for the moment. On paper it sounds good, but who really knows. But then again it doesn't break the bank so I may just have to get one.
