I have received some feedback about the steel guide tongue being too soft in some cases. So I went ahead and made some new ones from 1095 spring steel. These are .032 thick and are the same shape as the steel, just with no chauffeuring. These are also .4 grams lighter so you may need to add a little weight to the front of the Fang. The blueing may come off when soldering depending on the type of flux you use.
I am offering free replacements for anyone who purchased a kit who would like one. I am also offering to replace any guide tongues on the Stalker and Fang chassis I have built for anyone. Please send me the chassis only (no wheels, motor, guide, etc...) and I will install a new one free of charge. Please message me here to get your replacement.
