I have to ask. Angelblade, what do you plan to use the car for mainly?
By the way.. Boost refers to advanced timing. Blinky refers to zero ESC timing.
Mod motors are motors with less than 10.5 turns.
A 4.5 is very fast and draws a ton of power. It will tend to overheat a Tekin if you run it for more than a few minutes at race pace. Using 2 or more capacitors is recommended to lessen the likelihood of thermalling your ESC. Tekins are awesome for boosting a higher turn motor like a 17.5. They are not an ideal choice for a mod motor. Despite this they offer combos down to 2.5. I never understood why they do that.
