I would bet the issue is hiding in the rear as the RB6 front end usually has a boiler plate setup.

Just saw from your setup sheet that the rack is backwards to calm the steering. Turning it around should make it more pointy.

I run on medium grip carpet. On the more open fast layouts we put down, the car is insane, soooo good, but, the tighter tracks with sharp 180 hairpins, she pushes off power terrible.
Im trying a shorter wheelbase next week, moving the hub 2mm forward. I will say flip your rack though, and get at least 20g under the steering bellcranks, that REALLY helps.
Ive a few things to try with advice from the UK team guys, so im eager to get the balance right, as like you, lots of rear end, just need the front to start gripping a little better, but its a fantastic car, on power corner speed is just spot on.
Also, try going one hole out on your rear tower.

Thanks!
I went back and read my radio manual again and found some options in it that I did not know existed. So I am going to try that before I start changing things on the car. The only reason why I am trying the radio is that right now, on the front, that is the only thing that is different between our two cars.
As for the rear shocks, I had to move them to the back of the arm to help with the rear grip. Once I did that I had the rear just the way I wanted it to feel.
So next trip to the track I am going after;
Radio changes
Steering rack change
Weight on front end
Playing with the rear hub spacing to see what that will do.

I moved the shocks, because it was easier to do at the track. Maybe my next step will be to move the speed control behind the motor like you suggested but I need to get the front to feel like I want it to feel.

Thanks for posting your setup Kraig, I am wondering if the change in the front comes from the RZ6 directions showing the hingepin block on top of the chassis instead of under...

I had 5k in my diff and that didn't work out so well. I will get some 2k and give it a try in the future.

I am headed back to the track tonight to try my changes. If needed, I will swap entire front ends between my car and the kids RB6 and see if that makes a difference. It shouldn't take to long to do that.

Thanks for clearing that up, it looked like they wanted the hingepin over but the shaded image shows it the right way. Thanks for clearing that up.
Now I have everything I need to get the build started. This will be a fun one.

I made a few changes to the radio and now it appears to be reacting the same way as the RB6, front end wise. I didn't change the car at all but instead added more gear and the lap times kept on coming down. I think there is still more to be had but the motor temperature started going up. So next step is to install a fan.
