I have the hv maxx 4.5 that beats a 8xl mm.we used the exact same batts.true rc 8000 4s lipo.My truck is about 3mph faster and the acceleration is exactly the same.our trucks are the same weight also.my truck has also beat a 4s quark w/ neu 2200kv motor not sure which one but I know the kv.my truck is 10lbs 4oz and it runs great.the only race i lost was a lehner 1940 9 w/a quark and 5s 8000 mah true rc batts,but he didnt beat me by much.to sum this up Im glad I bought the novak I beat the crap out of it and it never gives me any problems.
