If you already have the 20P and want to get rid of it, I'll buy it off you... I need a few more for the brushed motor test birds... Aside from that, you have a great motor picked out. It'll be a 3cell motor though... If you want to do 2 cells, then you need the 2212-26... But 3 cells is the way to go for 90% of everything out there in that size.
