been having a problem with my buggy

[Hyper-5]

would a Castle CC-BEC-PRO V2 Battery Eliminator Circuit 20-Amp be any good?, atm l am runing a 3s 11.1v battery

You really don't ned the pro to run just one servo. It's an overkill. I use the normal blue one and have no issues at all driving some pretty hungry servos.

[Hyper-5]

ye, but ldk if its my servo or not, l don't know what the problem is

Like I said earlier. It will have to be a process of elimination. Can you borrow a servo from someone to try? If that checks out maybe try another radio system and just keep going till you work it out. Try to borrow friends components till you work out what is wrong.

Would you have an old nimh rx pack around for testing instead of a buying a bec?

[Hyper-5]

na, dont think so

[Hyper-5]

has anyone else had this problem before? l dont think its my servo cause there is a delay in my acceleration and my servo ( delay in everything), this is my current setup:

[_paralyzed_]

my guess is a weak battery or the esc itself.

until you try a rx pack or a different battery we can't help you

[Hyper-5]

l dont think it's either cause lve tried different batteries nd esc, l dont think there is enough current goin through the car, or to much

If you have tried different batteries and esc, that only leaves the radio and servo(s)...

[Hyper-5]

l have changed my radio nd it's not that, l havn't tried a different sero, but if l get a BEC will it solve the problem l am having atm?

If you can get your hands on a servo just for the test that would be the easiest way. If the issue is still there with a different servo then the BEC would have to be the culprit.

If you have a multimeter you could check the voltage coming from the ESC to the receiver and see what it does when you turn the servo from left to right. If it fluctuates wildly then it's the BEC guaranteed and is not then it is the servo.
