So this is my 1:16 scale traxxas mini e-revo, I have already upgraded the motor and esc to the castle sidewinder v2 kit with a traxxas 1406 4-pole 5700kv motor with the tenbol big block mounting kit. I have upgraded to the dual traxxas servos as well. It also has RPM carriers installed, and Pro-Line speed hawg tires. I currently run traxxas 2s and 3s lipos in this car because they are easy to obtain at my local hobby shops.
