a 1515 1Y will give you the power but motors tend run at w/e temp they feel comfortable lol nothing is forsure with temps from one setup to another, my 15152.5D on 5s in my buggy runs 155-160 during the LONG runs but it levels off at that temp, but if your maxx is that heavy without batts id atleast get a 1515 a little extra motor never hurt nobody, i dunno how well you lipos will hold up tho because the 1515 1y can really pull some current
