I'm a newbie so don't flame me. I got a wraith with a rspro that I put a spektrum a6030 servo on it and for some reason, when the wheel caught on something, I loose all power on the motor and the servo only respond on one side. I pick it up and everything come back normal. Do I need a BEC or here is something else that need to be done?

thanks guys

That's a Brownout. Try a glitchbuster capacitor first, then look into a BEC.

Spektrum servo's are made by Savox, so they have the same caveats.

Not sure what you mean, I already have a capacitor on the speed control post but can't tell which type. Will have to make some research tomorrow. At least, I got some way to look at.

thanks

A capacitor on the receiver as that's what is browning out. A

I just made some reading about this and I think I will install a castle BEC.

thank you guy!!!

the rs cap is to small... bigger cap or BCE will fix you right up....
