Did yours have a Tebo Ifmar world champ sticker on the outside of the box?

My kit came from Kyosho directly so it might be a new thing.

I guess that means we are not getting a new updated worlds kit. Was hoping for a worlds kit with the new chassis, the alloy steering rack like the rt6 and the tebo medal thingy.

Tebo posted a story about them on his blog here. http://jtprc.com/2013/12/30/good-luck-charm/ Still not sure what the deal is with them in kits. I guess I just got lucky
