5s1p is far from ideal for an MT, you need a 2p setup if you want that 'punch' factor, plus Castle state you have to run a 2p setup with their MMM escs otherwise the ripple currents from the cells dropping their voltage under load may cause damage- warrenty wont be honored.

Given the nature of the thread, I wouldnt even concider MA lipos with a 50% discount on price- go for the NeuEnergy, Zippies, Mikes new lipos in the RCM store, or the Elite 35c cells that have had good reviews.
