So i just did a little test with my new setup, T8 1550 + Thunderpower 70C 3850mah 6S.
Geared 14/44 for a theorytical 42MPH / 67KMH.
First off all truck is now around 4.3KG.
Second: it's really smooth but stupid powerfull/fast.
Third: everything is now too soft, have 10/15/5 in my diff's and i hate it.
also need stiffer springs i think, it just moves around too much with the green's too be stable.
