I have this dc heli called protocol. It charges from the remote which uses 6 aa batteries. So I got a 9 V wall wart. There's a couple problems with the wallwart when I used my analog multimeter to read the voltage it was reading 60 V. When I measured the batteries in the remote ball the remote was on I put positive to positive and -2 negative but the needle turned backward only when I switched around so that positive was on negative and negative was on positive did the needle move forward. Same thing when I turn the remote off everything was plugged into the proper place.
So my questions are I just need this to charge the helicopter can I use a cell phone Walworten or would I have the same problem? Do I need to build a voltage regulator?
