I've written a whole spiel about this on another XB4 thread. I have been struggling with this too, especially off short sharp ramps. Nearly every time I popped over this particular ramp the car would just end up nose diving into the grass and ending up on it's back. I ran my spare car (Caster S10B) in alternate races and it behaved perfectly.

The upshot of all the discussion was that the car is super sensitive to rear shock settings due to it's rear end 'lightness'.

If the rear end is underdamped the suspension compresses, bottoms out and abruptly rebounds, flipping it's butt right up in the air.

The answer is to run rear weights (under Lipo, under gearbox or suspension hanger or all of them) and up the damping. It doesn't need much, just enough.

I set up a wee ramp in the garden to test this and went round and until I was dizzy! It didn't seem to matter what pistons I used, but I suspect 2 hole may be better than 3 hole. Anyway, the results seemed positive.
