Just an fyi:
Last time I has my xb4 apart due to what I thought were transmission problems, I found that the motor was touching off on the plastic chassis tub either due to motor plate or chassis flex. The rear bearing in the motor was toast. I shaved the plastic tub in that area to give the motor plenty of clearance, so hopefully all should be fine now.
Check it when you can! It could cost you a motor.

Edit: I completely forgot to mention that back plate on the motor had been tweaked right where it was touching the chassis - I imagine this misalignment is what killed the bearing, but it was caused by the motor touching off either way.

I have used this servo before in RB5 without a servo saver and it stripped. In the xb4 it should be fine though just check your saver frequently and be sure it does not bind up. The torque is enough, speed is enough. Just not titanium. I like the BLS451 in my car now more than the savox 1258, it centers better.

I too had a endbell bearing go out. The screws holding it to the can being missing didn't help. oh well.
Now you have me thinking the flex/contact worked the screws loose ( two piece can orion ).
The chassis contact is there I didn't think about it being that severe.

That is exactly my story, with the same motor even. I lock tite'd the crap out if those screws, and have had zero problem in the past two cars it's been in - the top two were perfectly right, the bottom two closest to the contact point were very loose

I tried the progressive springs tonite but they immediately caused traction rolls in the faster turns. on some pins or a lower traction they could be very good as the car seemed to react a little quicker with those springs on.
I also played with the stiffening screws by simply unscrewing a turn or so on various ones. I settled on the center 4 screws tight and the outer 4 corners loosened a turn.
I tried the rear shocks inside on the arm too. Car was a little more forgiving that way. Not necessarily faster tho. it seemed to smooth out the cornering a touch so the car wanted to carve the turns just a little more.
oh yea. one more thing...I am running some 30wt oil in the rear shocks. The 300cst is close to 27.5 wt and was really good but the car seemed to bounce just a little over smaller bumps on the track. The 30wt seemed to make the car smooth out over the bumps.
Hope that helps.
