If your speed is off from the calc that much I'm guessing you either entered something wrong or your batteries can't handle the current

No... everything is entered correctly and my batts are Neu Energy 3s 3900 25C lipos, so I know they can handle the current. Its actually more where I drive vs something being wrong with the truck or the calculations. I'm sure if I got a reading during a street/pavement run the actual speed would be a lot closer to the speed calc's theoretical numbers.

The terrain you run on is certainly a factor to include in your calc for top speed and heat of the system.Very astute of you to bring that up.When doing your motor and esc ratings, I think everyone should consider this variable in factoring thier speed and run times along with all the standard stuff,because it REALLY is a BIG factor.I allways do it on pavement,but come to think of it,these are really ofroaders and it Does HAVE A MAJOR EFFECT on motor and esc. That being said,I will run this truggy primarily on pavement,because I consider it too small for any real offroad use with bashing in mind. BrianG ...is that 10,000 plus post cout for real? If so ,you must be the most schollary amoung us, when it comes to this subject,and I will heed your wizdom.When I get it installed,I will post results on pavement,and dirt.

Got the medusa 36-50 and hobbywing esc installed and took it for a some quick runs,the esc is a pain to program to me,and am waiting for the programming cards to arrive from rcm,but I got it programmed enough to run it on pavement and it was a tick slower on 14 tooth pinion,the same setup as the velineon combo I had before.18 tooth will not fit as it touches the motor mount screws.The fan on it runs constantly and am not sure I like this esc yet,but the hot weather is almost here and maybe this is a good thing.Massive footprint for sure but stayed cool and smooth for the first speed runs,withe the medusa getting about 130 with no body fitted.
