Issue with new wraith, ESC, battery???

[Stainless02]

Hi all, I have an issue with my new (one day old) axial wraith. I will start with a question first...does the stock AE-2 ESC have some kind of overload protection.

The issue I am having is when crawling in my rock garden it will get to a point when trying to steer hard (maybe against rock) and the ESC basically shuts down, and beeps incessantly at me, when I take the bonnet off it is flashing red and green. I can switch it off and back on again to reset it but it wil happen again. Battery is fully charged, it is a arrowind 35c 5000mAh, racer lipo pack 2s 1p 7.4v.

I am currently charging an old nimh to see if it does the same thing or if it is the lipo causing the dramas. Just trying to go through a process of elimination.

.........................

Ok so after a couple of more runs both lipo and nimh i have it narrowed down to the servo load. I can fang around the garden/ rocks and there are no worries, full noise and full turn(which flips car) and no issues. The issue arises when crawling and I have the front tyres up against an obstacle, if I try to steer when the wheels are essentially locked, then it shuts down and starts beeping at me. It is as if the servo has a protection circuit. Has any one else experienced this and how did you or should I look at fixing it.

Thanks for any advice.

Get a bec.

Castle Creations isn't known for having a great or even good internal BEC on their ESC's, as Meatwad said your best bet would be to get an external BEC, the Castle Creations 10a BEC is what most use in their crawlers, from comp rigs to scalers.

seems like if you have a bad internal bec in front of a good one that you add, it will only be as good as the bad one

No seems about it when the bec from the esc is disconnected.

thanks for asking this question, I have the same issue on mine. And thanks guys for answering this question. looks like I'll be getting a CC BEC.

[Meatwad]

Also keep in mind that the cc bec is not the only player in the game, but it is the best. Because of the ability of such a high voltage input and output voltage programmability.

Point taken Meatwad! Just want something that's going to last for the long run!

Hi all,

well I went down to my LHS and he gave me a cheap BEC to try, wired it up and no dice, it still was not working as it should. So he gave me a hitec servo and bingo prob solved.

At this stage (funding limitations) I will keep the servo that he loaned me and the BEC and it only has a bit more power than the stock one. I will upgrade both later.

Thanks for all your help.

Weird Ive had the truck around a week and im running upgrades gears,links,aluminum steering links and aluminum horn with 50 degree turning axles.

Im still using the stock servo even thoe i have a metal one and it works just great. The truck does beep at me thoe when its standing still.

I thinks its telling me Itwants to go!

Hah! Same here. The stock servo is running fine for me and I'm driving hard enough to break stuff almost every time I go out. And my truck beeps at me too. Is this just like a heartbeat to let you know that it's powered on? I'm sure it beeps all the time, but you can only hear it when it's standing still.

It's the castle beep...
