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!

Try a battery with more amps or a higher C rating, or both maybe.

And you have it geared at?

Change your gearing if it isn't good already and def get a higher c rating on your battery. I won't run anything less than 30c. Your battery could be toast. Have you checked the voltage on all the cells and balnced it properly? I had a 3s that got a bad cell that would take a charge but it discharged quickly that did something like you are describeing and I was told at the time it was because I had a 20c battery. I have 1 30c now and the rest are 40c or 45c and have not had that issue since.

It was my servo!
