I have allready an ultra light electric losi 810. it's around 6.5pound and powered with 3s lipo and castle 3800kv 1410 motor. It's very smooth and top speed is incredible but there is a lack of torque I used to have during racing with my regular tekno mbx6 1/8 buggy outdoors. I'm not faster with losi on a blown out track with big jumps and every little contact with other cars drives my car very easily out of the line while the other car keeping it's line. It's a big disadvantage during racing. So when I get tekno buggy I would prefer heavier 1/8 setups to deal with other 1/8 buggies especially for outdoor tracks. Lighter means not allways faster
