A good site is horizonhobby.com! Flight packs? No need to worrie bout those, as long as you have 2 micro servos (5-7 g's) and a micro receiver (5-9 g's). Get a JP 600 mah 7.2v NiCd battery, or 250 mah. With those it flies well! EXCEPT, airtronics/jr dont go with futaba nor hitec and vice versa(the receivers). An GWS 2 amp ESC should be well!
Chargers, as long as they get charged with the right current it doesent matter!
Here are some acessories links;
