I`ve put atleast 40+ packs of 5s 5000mah (22-23min run time) on my RC8T CE tekno v4, with a cc1520 1600kv, and havent touched the driveline once since new.... This thing is the strongest bugger i`ve seen.
I`ve landed on full throttle ALOT of times, and used it hard on both gravel and black top.
Jump 30-40ft every single day i drive it.

i should have done some more service along the way though, cause the rear diff got sloppy (worn), and i think it`s about to wear out the pinion/sun gear now. So i should had opened and reshimmed it after 10-15 packs, i know ;) But a 24 dollar diff from ebay, and i`m all set. I also have ordered a complete bearing kit for it, to do a big service now.

I have no doubt it would handle 6s without any problems, all day.
