Hey everyone, I am jumping into the electrics. Picking up a trex 600. How do I decided what scorpion motor I pick for 12 cell? Also what pinion? Can someone point out the link to the motor pinion headspeed calculator that I am sure I have seen just can't find. Thanks!

go for the 4025-630 on a 12T pinion , or if you like a bit more , try a 13T pinion on a 100% flat line throttle , very enjoyable 6mins using two 3000 packs , 35/45c is what i use , you`ll love it

+1 for the scorpion 4025-630 12t or 13t pinion. This setup seems to be powerful and efficient.
