hi guys ... I want to ask .. 
recently i bought a new motor tamiya ultra dash and hyper dash 2, when I try the ultra dash in my evo xmods. yhe xmods direct his heat and did not until two minutes played a direct battery runs out and it happent again when I try hyper dash. 
so the question is, do I need a capacitor in the motor like the stage 1 stock from xmods? If yes, what  the size of capacitors for use in ultra and hyper dash? 
thanks ..
