Wraith loosing power?

[Stan3535]

Hi there,
My wraith had a Holmes hobby brushed torquemaster 20 Turn in it running off a Castle sv2 ESC with a Castle BEC. The servo is a Solar 772. My batteries are 3s 1000MAH 20C.

As I crawl it slowly looses power to where I have to let up to zero throttle then it regains power. Kinda like if you have a air bubble in your car brakes you let up and re apply and they are fine....temporarily.

So I have swapped everything one by one to trouble shoot this and no luck. I switched to a Mamba Pro ESC, Traxxas 21 turn. It still does the same thing. Gradually looses power. I even ran the Mamba Pro with and without the external BEC. So I do not have another BEC to try?

I checked both ESC settings on my laptop.

Any suggestions as to what might be wrong would be HIGHLY appreciated!

Thanks a bunch! "thumbsup"

Mine did the same thing with a new hitec 8380 servo so am intersted in suggestions also... I had to turn my bec down to 5 volts

So after you turned your BEC down to 5 did the motor and ESC hold steady power? I would think of doing just the opposite. Turning up the BEC?:shock:

Is there a way to troubleshoot my BEC? the green indicator light is on?

Sounds like the "C" rating on your battery is at the low limit for the setup you have. Also, by chance it could be the settings on your esc. Or gearing, what's the temp of the motor when it stalls out?

So I just tried a battery with a 30c rating. Thats the highest I have. Still no luck. The motor in nice and cool. This will start about 4 minutes into crawling and get mor frequent. The settings on my esc are the same ones I have always used with better luck. Are there any lettings I should look for?
Thanks for the help

It was my servo! "thumbsup"

What do you mean it was the servo? Im interested as I just bought the same servo. So far its been nothing but great for me,but then again I only had it on one outing. Was it draining all the power or what? I have mine running at 6v with the cc bec and I use a regular 10th scale 2s 5000mah lipo and havent seen any problems. Im using it on a scx10 with stock 27t motor,so maybe the bigger tires and faster motor might put a bigger strain causing it to work harder draining more power? Im interested to know because im picking up a wraith this weekend and was going to put the 772 in there,but maybe I'll pass
