RE: Is this LiPo worth the money?
As Access said, parallel lipos is not really needed. It's good to slightly stress a lipo, they are temperature sensitive and won't give their best until they've gotten up to around 37 degrees c. Professional speed runners will pre warm their lipos in electric blankets before making one time runs.
Skunkworks,
It's a dirty little cheap setup for the moment, an 8L Feigao rip off, EZ-run 80 amp 4s controller and the Turnigy lipo running through Mod 0.8 gearing. Planning on dropping a Mamba 2650 motor in there when I get some dosh. Mainly it's just a test bed for the E-savage electronics I want to use.
