Maybe mine is possessed..
This is another one of those HPI cars that never quite drove correctly from the getgo.
The biggest complaint about my CupRacer is that it likes to make left turns, but can't make right turns very well, push-under (plows) under acceleration. Geometrically the steering linkage and suspension is set up evenly. I even swapped the front/rear diffs so that I can change diff setting on the front (CupRacer's front diff comes with that silly 3 spring setup). The diff isn't the problem, I tried it from spool-like stiff to soft, something to do with the overall balance, drive train, and the torsional twist from the motor under power. I applied a lot of rake and added weights to the front too, still only marginally effective.
My BSR M-Rage is almost identical to the CupRacer's layout, but it handles fairly evenly left and right given the motor orientation, and drives 10x better with only a few hours spent setting it up. Car is dialed, no extra weights used, and fun to drive. So it looks like HPI got its ass kicked by some cheap Chinese brand chassis that uses fake CF double deck and mediocre at best materials.
