Steering Issue 2016 Blackfoot

[LeMans77 1]

Hi, I have a 2016 Blackfoot rarely used... I am having issues with the steering its fine one minute then all of a sudden the steering on car doesn't respond to the input on controller.

Anyone any pointers? 

The controller is a Carson-model sport and electronic speed controller is a TBLE-025.

All worked well when build was initially finished.

What servo are you using?

Carso Reflex Racing Servo CS3.

Check the servo plug is fully sitting in the receiver and that there are no cut wires or loose connectors in the plug . If that is all good then have you got a spare servo ?, if you have unplug the steering servo , plug in the spare servo and test . Do you have any other cars you can test the Handset with ?

Thanks for feedback. I've stripped down steering connection to Servo and the part J7/J10 is threaded. 

Do I need to by the whole J part or can u individually bay the damaged part?

Forget that dinky standard plastic servo saver assembly. They do not work very well and it will soon fail again. Also, you will need a parts tree as you can't get it as a one piece.

Get one of these: http://www.rcmart.com/tamiya-51000-servo-saver-high-torque-type-black-p-14487.html

Get one of these. https://www.gpmparts.com/servo-saver-for-ko-sanwa-jr-gpm-ss11-p-90073040.html

And better yet, get one of these: https://www.gpmparts.com/aluminium-hitorque-servo-saver-for-25t-spline-output-shaft-1pc-gpm-sh025tms-p-90073183.html with one of these: https://hobbyking.com/en_us/aerostartm-as-559mg-high-torque-mg-servo-9-35kg-0-13sec-55-6g.html

That Carson 3kg servo is definitely on the small side of things for a Blackfoot.

Great thanks for this, I take it the hi torque aluminium Servo and a high torque new Servo a straightforward swap?

You're welcome.

Yes indeed they are straight forward replacements. It's a standard style servo, just more powerful. It has a standard 25 spline Futaba style shaft, so that's a bit more common than the 23 sline you currently have. As you can see, the servo saver in this link is a 25 spline unit. https://www.gpmparts.com/aluminium-hitorque-servo-saver-for-25t-spline-output-shaft-1pc-gpm-sh025tms-p-90073183.html

If you order the new servo, you can give the standard servo saver another try if you still have the J parts tree. As you can see in the user manual, there are both an adapter for 23 spline (J10) and one for 25 spline (J7). So you can run the stock servo saver and wait until it gives out, before you purchase the upgrade.

If you choose to upgrade to the GPM servo saver, I'd highly recommend these rod ends as well. They are not a necessity, but they do tighten up the steering nicely.https://www.gpmparts.com/nylon-ball-links-with-58x3x6mm-balls-16mm-long-for-110118-scale-3mm-clockwise-ise-and-anticlockwise-turnbuckles-12pcs-set-gpm-bl3165836s-p-90072999.html

They will screw on to your existing turnbuckles, so they are a direct fit in that regard. You will need two M3x10 and two M3x12 button head screws to install the steering arms if you choose to upgrade the ball ends as well. Use a bit of low strength thread locker such as Loctitte 222 with the M3x10 screws for the screws that fasten the steering rods to the servo saver - the holes in the servo saver are threaded. The M3x12 screws should be used without thread locker to fasten the other end of the steering rods in the steering knuckles where the ball studs normally would be.
