yes get frog/brat parts and do this

copied from RCMT

Hey you guys with a King or Super BF listen up

Tired of all that steering slop from the bellcrank/servo saver?

Well this took less than 2 hours from disassembly of a running

truck to outside for a test run. I've done it to both the king

and super BF's with great results.

I took the crossmembers from a "frog" and you'll find it with the chassis parts bag on the king and super models.

(orig BF has red parts)

I dissasembled my super, you actually only need to take off one side of the

suspension and Frame screws to just lightly spread the front of your frame

apart to swap out crossmembers.

Then pop in the older style crossmebers and bolt it all back up.

Servo centered in chassis just like bellcrank.

I then took a kimbrough #121 servo saver drilled out the farthest most outboard holes to 3mm and put in some tamiya ballends. I placed the ballends down, under the kimbrough unit. Then hooked up my steering linkage and finished re-assembling.

This keeps your steering servo centered and eliminates all that slop without hacking up your chassis. All this and out running in less than 2 hours, performance was much better, the truck went the direction I wanted regardless of the bumpy terrain unlike before.

BTW

the crossmember in question is included in a new kit, same parts bag as the chassis pieces.

Another tip,

I was playing with my super chassied Monster Beetle chasing some kids around picnic tables and caught a wheel on a table leg, oops. I pulled the screw through the H part where the wire brace bolts up.

So I yanked a new H part off my frog and reinforced it. It should last forever now
