so when I go to use my car it works perfectly for awhile but then it seems like something is interfering or cutting out my radio signal, I hold the throttle and it just uh. what is the word.... pulsates? not like it wants to stall it just gas no gas gas no gas at like 1sec in between each. if even 1 sec. I changed the batteries and such but that didn't seem to work?

Can someone help me out pleasseee lol
 
Going flat is another way of saying losing power. You could have gotten some bad AA's; it happens. You may want to consider upgrading to a rechargeable battery pack, which will save you a lot of money.
 
:\ok i went to my lhs and he told me that the best batteries asside from nihc recharge one is energizer lithium so i got those still pulsated hmm maybe its my servo?
 
It could be your servo. Did you run through water?

Another way to test it is to swap servo connectors on the receiver (plug steering into throttle, and vice-versa), to see if it still pulsates. This will rule out your receiver and transmitter.
 
I did that and it seems to behave the same way. I've notived it doesn't pulsate when I pull the trigger on the servo. I wonder what is going on?

it makes a low humming noise though. when I pulle throttle the full way back it seems to stop humming.
hmmm
 
So, the servo acts crazy regardless of which port its' plugged into? If that's the case, your servo might be on its' way out.
