Rustler VXL Problems! OMG, please help.
 
<font size="1" face="Myriad-SemiBold"><font size="1" face="Myriad-SemiBold"><p align="left"><span style="font-size: larger">Slow blinking red light!! Brand New Rustler VXL and bought 2 extra batteries. We charged one by car battery and the other battery was charged in the house for the 8 hr time. When we plug in the battery and turn on, we can run it at almost full throtle for about 6 secs and then it bogs down for about 4 secs and then nothing. It is acting like it is dead. We gave it about 30 secs and tried again and the same thing happens. I know it can't be the batteries, so what is wrong with the car? Should we send it back and get another one? Below I have included the light indicators from the instruction book. Thanks</span>

Did you turn off the lipo cut off? am assuming that you are using NiMH. You should be able to turn that low voltage cutoff off. That is where I would start.

What kind of batteries do you have and how are you charging them? The VXL ESC has a low voltage cut off built in. Most NiMh batteries will drop below the cutoff voltage during hard acceleration and cause exactly what you are describing. First make sure the batteries are fully charged then Shut off the low voltage cutoff by putting the ESC in NiMh mode. It's pretty simple to do. Just hold the ESC button down until you here the ESC make noise. I want to say it's something like 6 seconds or so.

He answered his own question without even realizing it.. The batteries went into LVC cutoff... slow blinking red light.. Thats why I don't run Mimh batteries with a brushless motor...

Well, he can still run them. It's just that the ESC is erring on the side of caution. If someone started with LiPos, it would be a good thing it was set with the LVC on from the factory, yes?

In the meantime, it isn't going to hurt his NiMH. It will just drag the voltage down a bit until it gets up to speed.

Cancel the low voltage cutoff by following the programming instructions and don't worry about it. When you're ready for more performance and to shoulder the additional responsibility of using LiPos, you know what to do.

And the ESC automatically resets itself to Lipo mode everytime you plug in a new battery.

Traxxas has the best phone in customer service. Why don't people use it before damaging their stuff. Kills me.

After further reflecting on this, I'm not sure this thread is worth an "OMG!" in the title. :)

JeremyZ.. I know he can shut off the LVC.... :D

This thread definately wasn't worth an OMG.. especially since he had the answer right in front of him... LOL

Why don't people call traxxas before damaging their stuff... I guess it the same reason I never use a map... and I never get lost.. :eek:
Just human nature I guess.. People try to figure stuff out themselves and can't/don't bother to read the manual that comes with the truck.. and its oneof the best out there...
