Hey Kevin.. Glad you are following this. Please post your results! I ordered one last night. Shortly after starting this thread I contacted HPI asking if part# 068v101 would work with mini rotor and Willy said no it was for the inner rotor. He gave me part#210v101 which isn't in the catalog and was made for mini rotor. I contacted treats asking if could special order. Benji was quick to get back with me and said he'd put it on the next stock order.. Bah da Bing there they are!!! It's only been like a week and a half. Gotta love Treats!!
