Thanks for all your valuable replies..
Actually I couldn't Calibrate it..Once I removed the battery pack and connect it again..The ESC "AUTO" power ON...then start to blink with what I said.. LED blinks once, twice then three times..repeat & repeat again. No matter how long I press the button..no change and couldn't power it OFF.
ps. I never play it on water and I have opened the ESC box and no water there.....
I tried to unplug the fans from the ESC but not help
I just played this car for once...If the ESC dead...any other waterproof speed control can replace it...just read a new VXL-3S is around $900...
If it's a new car, it should come with a warranty card, you can get in touch with Trax customer service on-line to arrange post-back repair. The ESC is very durable not easy to damage, I suggest you to unplug everything and reconnect then follow the ESC manual step-by-step and try again first.
