Hey, if you can spare the extra 50 bucks, get a Hobbico Accucycle Elite. I charge everything from foamies to giant scale, and it is so easy to use. I have almost lost an airplane or two to batteries not charging on the wall wart, so the Accucycle has paid for itself. It also gives you piece of mind that your batts are actually charging. All of the people I have taught to fly I recommend this charger to. Sure its a little pricey, but if it saves one plane, it was worth it. Just my $0.02.
