Thanks Chris, I have a new bottle of powermax that failed on me, lots of content but won't pump into my on board system. I am gonna order that valve from Todd very soon, seems like a great system! Thanks for sharing.

Rush, the pack you mentioned will be just fine, it should give you about 6 flights no problem. With a stock pump, typically each flight requires just less then 300mah, I generally reset ECU "Battery" under INFO menu after a full charge or replace a freshly charged pack, and the mah will be cumulative accurately from zero.
