i just got through talking to these guys and calandra said that the picture on their site was an early prototype picture and that what i got in my bloody knife kit is correct.cause in the picture,i said i didn't get the red transponder the shiny turnbuckles or the red axle . i still think thats bogus....but as for the guys at irs. he said that he makes both shafts for calandra the yellow stealth is a fiberglass shaft and the black with red hubs that comes in the bloody knife kit is a graphite shaft, which is lighter than the yellow but not as strong...hope this helps you all...it did me.. boo!!! to the false advertising on crc's bloody knife.
