Ofna Gtp

[gimpygolden]

ok so heres the plan I bought one of these OFNA GTP Oval kitshttp://www3.towerhobbies.com/cgi-bin...&I=LXTCJ1&P=ML to run with my bros InfernoGT

I'm going to be running mambamax on 4s6000 MaxAmps geared 18-22/51 depending on motor

I would like to get 45-50mph so I was thinking either 10L (2458kv) OR 7XL (2382Kv). Witch motor will yield the longest runtimes and stay the coolest?(most efficient I guess)

What are the different characteristics between a L or a XL can? Does one draw more amps than the other with similar Kv's?

Do I need the torque a long can makes for onroad as there will much less resistance on asphalt?

What do you guys think would the best choice between the two, or if you have any other suggestions

thanks
