correct, for super truck. I just converted my stock so I can switch classes for the last race this season... I believe there was cheating in stock class with tweaked motors at TQ so I was thinking of changing classes anyway... even before the news of closing the track. I think I read somewhere that the YR was not a perfect fit and could generate enough heat to melt the plastic. I have an extra diff so I’m going to lock it with glue and see how it goes. I don’t want to pay $20 for 2.5m oil or $10 for the spool or cc01 gear drives if glue will work. If it doesn’t than I’ll try to cc01 gears.
