Don I saw the same thing lol.
We where all standing their near the flight line when the fly eagle guy was taxing out and the engine was popping and making all kinds of sounds and clearly was not running right. So what did he do?? Take off dead stick and crash

This was after another dead stick he did a great job getting it back and landing but the last one not so much.
We where all like *** is wrong with this guy? They just had a dead stick. Engine is running like crap. So I guess nothing left to do but takeoff and crash
