New to LiPo - using LRP Quantum/Turnigy7.4v

[TMRdevelopment]

Hi all, returning to the sport after a long time out, previously used Ni-Cd and then Ni-Mh towards the end of my racing days. The LiPo thing I am doing a lot of reading up on but to get me confident enough for my first meeting this Friday, can anyone tell me the best charge, discharge and storage settings for my LRP Quantum charger, using Turnigy 7.4v 4200 2S cells? Any help much appreciated
