To calculate motor speed, simply multiply the voltage by the motor KV. So, 4600kv * 8.4v = 38,640rpm. The idea is to use the lowest kv motor you can for the voltage you are using. Higher kv motors means more current, which means more losses, which means more heat. Basically, it's better to develop high power with high voltage and lower current than the other way around.
I agree with you on bashing, the 5700 is best on 2s and 6-8 cells. I choose the 4600 because mine will be raced and the 4600 feels better on the track on 2s. The 8000 pack is awsome in my T4 and fits almost perfect (had to move the strap screws up a little) and the pack is lower in weight (by 50 grams) than any 6 cell pack


Work because i gotta, play because i wanna

People here hate Nitro, I love it. I start it, run it about 50 ft from me and it dies, I go after it. Perfect exercise
