Quark 125 and a neu get you in the powergame. 5S would be a blast. IMO. the UE saver is the best savers money can buy.
Thanks Serum...I noticed Mike also sells a heatsink for the 125. Does that heatsink mount to the ESC case...or do you disassemble? I assume you disassemble, but since I've never seen one or worked with one I have no idea.
