Is this enough torque?

http://www.youtube.com/watch?v=h01_k9V5FyE had to share :) It's my Medusa 36-60-2000 ,which I keep hearing people say doesn't have enough torque for a MT :) ,with Quark 80b esc and SPC 8000 mah lipos.I love these lipos.I just got them but they seem to be very good.I pulled a 46 mph speedrun with 24/68 gears,which by the calculator should only be 40 with .7 inches added for ballooning.They are holding great voltage.
