It's just the next generation, but to be honest, do you need the extra speed on off road?, its not like we are using 3.5 motors. I think the ISTC was brought out to run cooler back in the day of bonded rotors, but 99% of motors are sintered now and they run cooler anyway
I don't know if i dreamt it but i think there is a new LRP on the way, so that means there will be a red version too.
