Hi all, this is the footage I shot a while back when the Yoder YS640 was delivered. I had some PC issues so I could compile it until now. This is the latest production model running the improved firmware U17 which has been superceeded by U18. Which is on the way. Perfprmance has been amazing. I have allot of cooks on the thing and it has done nothing but cook great food. Thanks for watching!
