Oh, and I originally spotted the PowerForce 30 amp on MaxAmps when I was buying my balance tap adapters- they wanted $109 for it- a full $30 more than I found it at HobbyLobby. highway robbery, didn't feel to good about buying even the balance adapters from MA.... anyway HobbyLobby has a 40 amp version for $100 if anyone is interested.
