|  ok i have a question
i just finnished building my rig and am having a problem with my electronics i am using a futaba s3305 servo, CC sidewinder, integy 35x1, a spectrum 5ch stick radio and an ar6100e reciever, all on 3s. now when i first hooked up for the maiden drive with a 1500 mah 15c 3s i would turn the steering servo all the way to one side and my reciever would brown out and the light would blink if i never went full lock on the steering it would drive fine and not brown out, now i know what your thinking add a bec .. problem solved.. right? i dont know on my second drive i used a 1345 mah 20c 3s the truck was alot slower and no brown out but at times while pushing the throttle it would hesitate for a second and then it would go also while binding up on some high traction surfaces it would just stop all together and i would have to release the throttle and push it again and it would go. sorry about the long post has anyone expierienced this before any help is greatly apprieciated

The mah of the battery won't effect your speed. A fully charged 3s will put out the same voltage as any other fully charged 3s. It sounds like you need a BEC to correct your issues. ANY time you upgrade to ANYTHING over a stock servo, you really should have a bec to avoid any glitching or stalling. |

Mah & C do effect battery power but that 15C/1500 should be weaker than the 20C/1345. That little servo may even be ok without a bec. I wound make sure the sidewinder is set for brushed. They come setup for brushless and can do all kinds of crazy stuff with a brushed motor.

Without a servo saver, you're asking it to go further than the steering parts will let it, so its sitting there pushing and sucking power while your wheels are locked on one side or the other. That is when the weak built in bec's take a dump. | |

If your running 3c on a sidewinder with no external BEC. Then thats what the problem is. I learned the hard way. Mine would just shut down untill I walked over and picked it up, then it would come back to life untill it got to the next little bind and gone again. A CC BEC fixed it all.
