I have to say that weight plays a big issue.Also is it the new pro version with 5mm rotor?I run a old hv4.5 in my stampede,which is widened and extended with aluminum chassis,so it's got a litttle extra weight.I run on 3s and it's awesome.I wouldn't trade it for anything.The new version is supposed to have a much better rotor and rated power has gone up from 750 watts to 890 watts for 6 minutes..That is because the new 1 is supposed to drop motor temps and supply better power.( I spent some time talking to 2 novak techs to try and figure this stuff out.)So it might be great for what you want.That being said I just got a medusa motor for my emaxx,even though I had the novak because I was afraid it wouldn't be enough for me.But to go from hv in stampede to hv in emaxx would be very big step down in performance IMO.
