Which neu

[Jaron21025]

Ok i'm starting to get a little concerned about my motor choice now... I did the top speed with measurement thing you have here on the sight .. and it said i am only to see speeds of 34mph with my emaxx on 14 cells and 15t/51 spur.. that was with the Neu 1512/2.5d that i was thinking about going with.. but that's basically stock speed isn't it? and with all this money going into it.. this just doesn't seem right. so i put a different motor in.. the Neu 1512/2d and i instantly got 10 more mph up to 44 mph.. i would like this a ton more since i am putting so much money into my maxx. Does this seem wise?
