Want to buy RCM V3 Hybrids, what to use for center shafts?

[doo540]

I have 30 minutes of full throttle on my V3 (6s Neu 1515 2.5d) geared for 50mph and no problems. The traxxas Summit axles llok the same as they did new. I'm only running Badlands for tires. So far so good. Shizzon I will check later to today to see what fluid I used, I cant remeber right at the moment what it was.
V3 is a very, very nice unit in my opinion.
