Mad bull steering issue

[Bill1976]

Hi chaps, got an issue with my sons mad bull, steerings not working, it's trying to, as you can here it, but doesn't seem to have the power to turn the wheels, thanks in advance.

 

Could it be the servo? Not clued up with rc cars at all.

Just had to Google servo saver [emoji1787]

So it's the white bit on top?

Right I've removed the screw pulled the saver off I think? No different, very slight noise, like it's trying to move?

Sorry I don’t know how to see if the servo works ok? Do I need to remove the white bit that’s still on top of it? If so I just did this and it’s  no different.

 

when I put the servo saver back on i can turn the wheels manually and it grabs onto the servo  ok, (and turns it, ( as in it’s not threaded if this makes any difference )

Doesn’t turn mate, makes a very slight clicking noise, but no movement

[Bill1976]

Cheers pal, thanks for the help, much appreciated , I’ll  get onto it 👍

[Bill1976]

Replacing the whole lot sounds easier for now lol, I have previously sent it for repairs for similar issues, nice to actually try and learn a bit of maintenance, thanks to yourself

[Bill1976]

I'll give it a go from now on, got 2 boys who are getting into them so expect many questions!

Right I put a new servo in, it's exactly the same, I replaced it with a new power xl 36, reason being ( they have decided they want to sell the mad bull's and upgrade to an arrma granite ) so figured I just replace with original parts, I'd like to get it right before selling, any idea on where to look next? Thanks

Hi,  the servo saver is  the original one,  fits on perfect and ( used to work ok )  both the old and new servo do not turn even without the servo saver on, just make a very slight noise, but nothing turns,  throttle works as it should.

[Bill1976]

Swapped channel’s over, and they worked lol?. So what does that suggest?

 

 

[Bill1976]

Yeah the throttle turns the wheels, and the steering  powers the rear wheels

[jea]

on Some radios you can turn the amount of steering you have up or down.. Have you checked this ? . 

 

[Bill1976]

The receiver is bad because you tried the steering servo in the steering channel 1  and it didn't work  but the ESC does ? and throttle channel 2 for the ESC. worked and servos  do. The ESC should only work in the throttle channel. It may be better to get a new transmitter and receiver as a option instead of just getting a receiver. I don't know what brand you have and how old it is?

Right! Looks like I've been a dumb ass I'm afraid! Had a mess around with the trims on the controller, ( I had checked the steering trim before and it made no difference) didn't know there was one to adjust how much it steers, had a mess around with that, and it turns more than it ever has, my lad has obviously been messing about with it [emoji1787].

1111 - thank you so much for taking the time to help me out with my ( cough) problem [emoji849] I've learn't a bit from this if nothing else! [emoji106]

This seems to have been the problem, thanks for the suggestion jea, got there in the end [emoji106]

I think the  steering dial on the controller, was ever so slightly on,  hence the very slight noise it was making, and when I swapped the channels over, the wheels started spinning slightly, I forgotten now tbh, but I can swap them over and turn the steering dial back down and see what happens.
