You can still find the full-length HCR Ti Skid for the Revo...the 3.3 length is a bit harder to find, but you can cut a 2.5 length skid in the right place and it works perfectly! I am running a strategically cut HCR Ti Revo 2.5 Length Skid on my Extended Vantage Racing Carbon-Fiber Revo 3.3 Chassis and it is awesome! All I do is extreme jumping and extreme jump tricks and I have never broken a bulkhead. I also run a T-Maxx 2.5 rear turnbuckle as a brace between the rear body-post cross-brace and the rear shock-mount (with Tekno Swaybars installed).
All that white on the skids is the white paint from my ramp rubbing off onto the skids!
