Just got a note from Dan.



Dan is one of the good guys, but if you order one, keep in mind he is just another modeler like us and he's doing these on his off time and not as a business.

2S, 4, 5, 7 or 8S etc means you will need a power source that can give you 4 volts per cell. You could possibly use an old NIMH charger...
