I built my Savage Flux from ebay parts so I could use what is good and ditch what is bad, and I bought the normal MMM combo instead of the HPI label. Anyway, I have been running it on 4s with 20t pinion (used 3 times in 3-4 months) and I finally got some 3s packs to use. I went to change my pinion gear to 25T and did a single blip throttle test on the motor before installing and it worked fine. I installed everything back and took a 10 minute drive to go run it on an enormous open parking lot and I heard a glitchy noise. I thought my Spektrum was glitching. So I tried playing with wires...I braided the esc to Rx wire, my servo is a TG 7959 hitec so I thought maybe I need a bec. so I go to pick up my truck and blip the throttle again (the servo was working) and I notice the esc fan goes when I blip the throttle lol.
So... it seems like a glitching issue with the spektrum pro....but, why would the fan go on with the throttle? I use Trakpower 2s and flightpower 3s. What could be wrong here?
Oh..forgot to mention that when I blip the throttle you see the fan come on as per throttle input and the motor I guess moves slightly because the spur rocks a tic and then I stop. I also checked the light chart sticky above and re confirmed that the LED indicates I'm good to go but does not work anyway.

You stepped up the voltage AND geared up at the same time? This is not generally advised. If anything, you step up the voltage and REDUCE the pinion. Otherwise, heavy currents will flow.
