Potential steering or servo issue
 

Ok so I've noticed something about steering of my new scx10.2 rtr. It seems that when moving forward it won't steer to the left as much as to the right. However when I pull the front of the car up, it reaches that 45 degree point. Also I noticed that if I move it backwards and then steer to the left, it reaches the 45 degree point without any issue.

Sounds like it's got something going wrong in the gears. If it were a better servo I'd say rebuild it, but since it's not I'd just get a Savox SW-1210SG if you can afford it. (If not the SW-0231MG is good too)

Re: Potential steering or servo issue
 

Your problem could be a bad reciever, a weak bec, or a servo going bad. I have had a similar issue to what you describe with each of those problems ...

My buddy is running a Power HD 20kg wp servo and is very happy with the performance, on a 2.2 (5.9" tires) scx10 based rig, espicially because its only $22.

Re: Potential steering or servo issue
 

The truck is brand new (got it like 3 days ago) so I don't think it's the bec or the receiver. However the servo always makes a ticking sound when steering.

Also what's the deal with the left wheel moving slightly in and out? I checked the nut and the hex and both are as they should be. I hope it's just a brand-new-truck type of thing where it should run for some hours to get used to the weight of the truck etc.

Re: Potential steering or servo issue
 

To my understanding it's got something to do with the weight of the truck. If I hold it in the air, steering to the left is equal to the right. The issue is when it's on the ground :p I tried removing the servo horn and centering the servo via the controller but with no success. Could the steering shaft be the problem?

Re: Potential steering or servo issue
 

What kind of servo? If you want a low cost servo try a Tactic TSX55. It is a little more powerful than the stock one

RTR? If so I wouldn't waste time fixing it. Call axial there is some warranty on electronics. Tell them whats going on, get it fixed and worry about up grades later.

Re: Potential steering or servo issue
 

Yes it's the RTR version. Actually i didn't buy the truck directly from Axial and besides that i live in Greece so it's kinda difficult to call them :P

Re: Potential steering or servo issue
 

The stock TSX45 that the RTR version comes with. I'll check out that one.

Re: Potential steering or servo issue
 

I had a similar issue with my kit version, and I'm using a cheaper Radient servo. It seems to have went away when I swapped the plastic servo horn to an Axial aluminum servo horn, AX30836, and SSD's double bent titanium steering/panhard links, SSD00122.

But I was also having some trouble eliminating AVC with my Spektrum DX4C. Rebinding that several times, leaving one plug seems to have solved that issue as well.

Re: Potential steering or servo issue
 

I thought about the aluminum servo horn but isn't it too early for such an upgrade?

Re: Potential steering or servo issue
 

I don't know if it's early, I waited after several hard runs before swapping it out. I just didn't like how much flex the plastic one had. I was holding out on swapping so I'd have a little give in the system for a servo saver effect. But I couldn't make tight turns like I wanted, so I was searching for a solution, too.

Re: Potential steering or servo issue
 

I see. Well this sounds exactly like my situation. The servo horn right now is a bit loose and flex like yours was.

Re: Potential steering or servo issue
 

It's never too early for that. I killed my plastic one 20 minutes after opening the box!

Stock servos are usually crap.

Don't get a tactic. Get a PDI 20kg off Aliexpress or ebay if you want a cheap option, or something in the 70+ EUR range from Hitec, Savox or some other "big name".

Re: Potential steering or servo issue
 

Tactic stock servo is too weak with your grip. The TSX57 is the best of the tactic servos, but it’s still weak. Look around, replace your servo once. A quality one will usually set you back 60 to 100, but never replace it again


Hang up and Drive

Re: Potential steering or servo issue
 

The stock servo is pretty weak. It just doesnt have the power to fully turn the tires with all the vehicle weight on the truck unless it is moving.

Re: Potential steering or servo issue
 

Well the only time it fully turns is when the car doesn't touch the ground. So in your opinion, the Axial aluminum servo horn won't solve the problem right?

Re: Potential steering or servo issue
 

If you get a new servo you'll still need a metal servo horn to take advantage of the improved torque anyways.
