Any good LiPo charger capable of handling 4S cells will do.

If you expect to stick with RC, a good computer controlled charger is a must.

e.g. Accucycle, Intellipeak, etc.

They are worth the expense as they will keep you from accidentally ruining your batteries and/or starting a fire!

EDF Jet's need to be properly "broken in".

Make sure you follow standard EDF check out and break in proceedures, or you may damage the fans, motor and ESC.
