Come on Leo I know your eyes aren't that bad, look right above the RX through the radio box
. The cone is black, don't think Tony ever anodized the old grease cones. Either way his hardware is not anodized, so its safe to sake neither is his cone. I don't know if Tony is consistent with his marking, but my M5 is only marked on the bottom of the intake port while my M6 is also marked on the ISO block. If you can see the markings and M5 or M5 is not included I don;t believe it was worked on. My M6 just says "TC M6" and the date, don't remember what the M5 says. Don't worry a stock motor will be more than enough for you. An M5 will push it closer to 50mph, and with this hull will take a lot of skill to drive. Once your more comfortable with it, getting the M5 work done will make it exciting again.
