I am trying something new with the VTX8s myself, and I have used Castle's MM, MMM, and MMP, Tekin's RX8 Gen 1's, and Speed Passions SA V1's and V2s.

I am very hopeful to see the VTX8 out shine them all.

To be honest, I think the main thing that keeps some of the guys on the fence is the fact that the esc is sensored only. I know that has been the main reason for some guys I know not to try it.
