When i say best i mean top-speed wise
Ok well on my best bit char-g i used to have the following:
Dark Green Gears(Bit Racer 3:43 smallest ratio)
Red Lucifer Rotor(3.0)
After discovering the extremely slow acceleration of my rc, i trie different combinations. So i tried a 2.6........ it happened to have good acceleration, but thats not what i wanted. I tried myself another step down to the 2.35 or the NOS zz motor, whoa you wont believe the results i have ogtten with top speed. I fratically floored the throttle and watched it take off to a rough and slow start. I just got faster, faster and faster, it wouldnt stop it continued to get even faster.....
I am about to try the LXX "3.0" rotor with this gearig combination, ill check in once i get my finds, but as it stands right now, the ZZ NOS motor is the best when it comes to this.
