Good freind Frank soldridge crashes

Is he still running a Nelson motor in the malibu? The front end is different for the turbos. Frank just went to a 481X proline.. I just heard my son talking about the rear locking up in franks car when he let out. That is what one of the guys relayed to him. But we are still waiting for frank to confirm what happened. I see the door issue before the wheels were locked on the video. He might of backed off when the door opened. That would be scary enough to let out quick.
