I had only used hobbycity for plane stuff up to now. Bought a couple of in runner and outrunner motors, some battery packs 2s and 3s, a speedo for one of my planes, their $40 balance charger and these connectors. So far everything has worked great. The only problem I have had is the fan on the charger is a little noisy when it first starts up. I always order a little more each time I order. So far so good.
I think the have a hard case car lipo, I am going to try that the next time I order some stuff from them.
