I just saw that page today too, although that info is dated. The original motor wasn't up to the task so Dale has decided to try a different motor (that costs about 3 times as much as the original one). The delay will mean he won't have time now to make the flight to the West Coast before Oshkosh. For the latest update, go to Dale's blog:
