You have something off on your setup. Either your end points in the radio are limiting the servo throw or you have a mechanical setup problem. In my 48.3 with an MKS servo, I can move way past the stops if they were not installed. I had to use end point adjustment to reduce the throw both sides of center.
I am not even using the radio, just turning the wheels manually. The travel is actually being stopped by the opposite spindle hitting the front of the spindle carrier. The spindle with the stop screw never touches.
There is something I'm just not seeing. I checked all the suggestions that justpoet made.
Maybe it is time to disassemble and reassemble although I can't see how it could be assembled wrong.

Something is not right with your setup, take a picture and post it up, might be easier for us to diagnose what is going on. Only problem I have seen in the design, a very minor one, is the outboard steering turnbuckle screw can hit the a-arm at extreme droop settings. This is a minor gripe and not something that would reduce steering throw. Sitting at ride height you should have full sweep steering with no obstructions.
EDIT:
Before you completely disassemble the unit, disconnect the two outboard steering turnbuckles and see that each hub and the steering rack can make a complete sweep left to right. This might show you where the trouble is located and help you solve your problem.

After trying what Fasttrak said (assuming you haven't found the problem) look at the screws going through the ackermann plate holding the steering linkage on. If you omitted any bumpsteer washers or used the wrong ball end the screw might be hitting the steering top plate.

I opened the manual to see what you might be facing and the parts to see what could be hitting what.
The two parts that make up the steering set are the C carrier, part#TKR5194, and part #TKR5193, the hub (names are probably wrong but you get the idea). You are saying the front of the hub is hitting the carrier before the stops make contact on the opposite side? Do you have the steering setup with zero or half degree negative front toe?

That's exactly it Fasttrak. The front of the hub is hitting the carrier before the stop screw touches on the opposite side.
I had a problem with the steering turnbuckle interference too. I ran into Ryan Lutz and he had the cap screw that holds the turnbuckle upside down. That is with the lock nut on top of the turnbuckle so the end OD the cap screw that protrudes through the lock nut won't hit the suspension arm. Really great to have him help out but he is off racing this weekend.
I did take the steering turnbuckle loose and the hubs turn freely.

I just grabbed my buggy to look it over and with .5 degree of toe out I have quite a gap between the hub and the carrier once the opposite hub is hitting the steering stops. You really need to take a snap shot so I can see what is different with your setup, a picture is really worth 1,000 words. Get a good shot of the hub and carrier with the wheel removed, toss it up on a hosting site and post the link here.

I haven't driven both back to back, but I have tried a nitro, and I have to say. The throttle and how you drive a nitro is different. I could definitely get used to it.
But where people seem to like Joe's NB.3 setup for both, I can only imagine they would handle the same.

Do you by chance have the c-carrier reversed, left for right and vice verse?

Here is a picture of the stop screw when fully turned.
