The higher KV number, the more RPM per volt, doesnt mean the motor is faster, just spins more RPM per volt, higher KV motors are less efficient, which means heat

6s is 6 lipo cells, so thats 22.2 volts, doesnt matter how many of what cell you use, its a 22.2 volt limit......

2 BL motors is dumb really, the gain is more torque, so yoou can use the toque to gear up, but really its not much a gain..........

theres much faster stuff the LRP/Novak...... NEU, LMT, Pletty, Mega, KB, ETC And then low end motors like BK, feiago (sp?)

Lipos will only blow up if they are damaged like punctured or, shorted out..... Balancing doesnt mean the cells wont blow up, just keeps the cells voltages the same which makes the pack last longer, and have better performance....
