need help with ezrun...LED
OK
just tried running 3s lipo on my model with the ezrun 35a esc and novatech 540 3500kv motor.
I wired the ESC's fan to be powered off the reciever...
And I added another fan for the motor, also powered off the reciever.
Buggy ran fine for a few minutes...then I lost steering. I thought the servo went...but when I unplugged one of the fans the steering came back!
A minute or 2 later, I lost steering and then throttle just seconds later.
Again, I unplugged both fans...turned everything off and then back on.
I left one fan (motor) unplugged, but just seconds later the throttle shut off again.
When I lost throttle, i just had to turn it off and then back on for it to work again.
Whenever the throttle quit, the led on the esc was blinking green.
I looked at the ezrun manual but couldnt find what blinking green meant.
Im pretty sure it wasnt overheating. I could keep my finger on the esc heatsink...and even on the motor. couldnt have been more than 120 degrees.
And Im fairly sure that the ezrun esc blinks read if it thermal shutdowns.
Anyone know whats going on? Am I exceeding the BEC on the reciever? What does blinking green on the ezrun 35a esc mean?

RE: need help with ezrun...LED
just wondering why are u running a 540 size motor on a 380 ESC???
why are u running fans, is it getting hot?
The loss of steering could be because of over loading the BEC, hard to say with out checking the current draw, the BEC puts out 1.5a
The loss of throttle to me sounds like overheat protection

3.11. Over-Heat Protection: If the function is activated, the output power will be cut-off when the temperature of
the ESC is up to a factory preset threshold for more than 5 seconds. When the protection happens, the Green LED
will flash.

the 540 novatech motor/ 35amp ezrun esc is the stock combo on the Redcat EPX PRO models.
It works great on nimh or 2s lipos. Ive run a pair of 2s 5000mah lipos back to back without the esc or motor over heating.
I am however trying to run a 3s...and I also have tires that are at least 1/4 taller than the stock ones.
I thought the ezrun blinked red if it went into overheat protection mode. And I could keep my finger on the ESC when it would stop working.
Also, I could turn the unit off and turn it right back on and drive it for a couple of passes before it would turn off again.
I think the draw on the bec is what caused the servo to stop working.
I think ill wire up a battery pack to power the 2 fans and give it another try.
she sure is fast on 3s tho:
