Thanks for the links. There are some pretty light BL buggies out there. My goal was choosing lightweight powertrain components, not just saving weight by using carbon etc.

I have achieved the first goal, my electric conversion is 130 g lighter than my nitro version of the same buggy (even with empty tank). I chose a very small motor to avoid overpowering the buggy (it's for racing, not highspeed bashing), but it didn't go as planned: These Neu motors just make unbelievable power, the buggy is crazy fast.

I haven't been to the track to experience driveability and runtime. What I noticed is that without mechanical brakes, it might be harder to throw the rear end around a corner off-power. But I guess I can adjust caster, ackermann and the dampers to tune that.
