7XL Vs 8L on 12 cells..which is better?

[Rtsbasic]

Hold on a sec, because this is confusing me. The 7XL draws less amps, thus less heat, but it will produce more power overall, and with correct gearing will result in a higher top speed than the 8L? That doesn't add up, because on only 12 cells the only way to get a lot of speed is through pulling a lot of amps..correct? So presumably if I geared an 8L to hit 40mph, and geared a 7XL to hit the same speed (via steeper gearing), they would both need to draw the same power to get to that speed? Would the 7XL get there faster because its bigger rotor = more torque?

actually thats incorrect. the 7xl will NOT have to pull the same amount of amps to get to the same speed because of the higher gearing thus not having to work so hard. basically the torque allows you to gear higher for more speed while not pulling as many amps and having a higher efficiency.

also, i think that you should get BETTER runtime because of the motor pulling less amps.
