Ok. so I just bought an extreme flight yak 54 47". it weights AUW 2.4lbs, it comes with all the complete 3s combo (www.extremeflightrc.com/html/yak54e.html) and I want to buy an extra battery pack . please tell me if this TP pack would be a good choice http://www.rctoys.com/rc-toys-and-pa...BATTERIES.html

it's less C, but is 40grams lighter.........

thanks
