Charged battery

[L05tB0y]

Just put another battery in the car and it just does this

"this" is just a picture. If you want to post a video, you have to link it and post on youtube.
Did you test your voltage with a meter? That is step 1.
If your battery is good, make sure that your connections are good to the receiver.
Unplugg your servos and plug them in 1 at a time and see if you have any changes.
Inspect your wiring. Antenna too.
This is an old kit right? Chaffed or broke wires cause issues.
You can also try removing the receiver from the chassis and moving the antenna. Sometimes glitching is caused from bad mounting locations.
Do you know if these servos are stock?
If they are "high current" servos, you might need a bigger battery all together.
Just some thoughts.

Just put another battery in the car and the servos,s just twitch. No control over anything, am I doing something wrong. Sorry it won't accept my video

Took the receiver out, does this look right. I think I may need to bind it again.

I'm not sure if it looks good or not.
You need to follow along the wires and make sure that no insulation has been cut into.
You can try binding the radio also.
Are you 100% your transmitter batteries are good too?
Are there any lights on the receiver?
You can check your manual to see if they are "good" or "bad" lights.
That would also get you to some actual diagnosis.

I've just got my brand new transmitter & receiver and followed the steps to binding it, and it still does the same. Light on receiver stops flashing and when I turn everything on as said it just twitches.

Something I keep messing up during the paring process is not taking out the pairing plug after I'm done.
I have no other ideas when it comes to a Hobao radio

Yea took it out and still nothing, the servos aren't even trying to move

Is this ground wire broken/severed, or is this just “optical confusion” from some camera trickery?

Yes it's cut, will this be the problem. I can see the copper wire but only on the black wire.

This is what's happening even if I unplug the damaged cable. So only the brake servo is plugged in.

How can I post a video ?

You need to upload it to YouTube first, then you can copy/paste to here

do you possibly have a different radio and receiver , From another car you can test with ? or a servo/ lipo checker ?

It done the same with supplied radio & receiver but I bought a brand new radio & receiver (Fly sky FS-GT3B) and it does the same

I get 5.35v on my multimeter with 4 x AA batteries
And i get 7.10 with the hump pack.

 

[jimdavis577]

so according to habao that reciever is capable of 8.4 volts input .... have you tried plugging the batter pack directly into the receiver.... removing the on/off switch from the circuit ... if not ... just make sure your using the correct pins and that will eliminate the switch as the problem ... or you could plug the pack into the switch and disconnect the switch from the reciever and test for the voltage at the reciever plug you should see no to very little voltage drop to that point .... those switches are known to go bad

This is a reply to both topics you have open, because they are basically the same conversation.
I had bought a used XTM nitro buggy from eBay that was in fair shape, when I got it the servos did the same thing. They just twitched but wouldn’t turn. I was using a brand new hump pack nimh battery that was fully charged. Since my radio system was also new, I was sure the servos were shot. I ended up replacing them with some JX brand from Amazon.

Anyone near Ashington that can sort this out for me. ( I can t

I've tried that too

So did that work

 

[jimdavis577]

Sounds like it maybe the servos ...... maybe plug a good known servo in and see if it works
