Disappointed with my new mega...should I be?

[speed demon]

I seen a post were a guy was going over 80mph(in a rustler) and pulling around 1100watts. I figure at 50 with 24 volts that's 1200watts so I might be ok. I'm starting to think that the mega just pulls more amps then the medusa and that's causing the higher temps. If I have time tomorrow I'll just gps both the mega and the medusa with the same gearing and see if there is any speed difference since they both have the same rpm(will really close). Just running both tonight it seemed the mega was abit faster but I'm not good at judging speed.
