Serpent S811T-E "Cobra E" RTR 1/8 4WD Electric Truggy
This thing is scary fast on 6s. Put in a 19t pinion and it wheelies on command and wants to flip over, but runs very hot. Stick with stock pinion! Great truggy. Very durable. Rtr radio sucks... Not even close to the one pictured. But my airtronics will take care of that. Love it!

Serpent S811T-E "Cobra E" RTR 1/8 4WD Electric Truggy
Great solid e-truggy, I was so impressed with serpent 811e-buggy rtr that I decided to get 811T E-truggy rtr. These rtr’s are really race ready, just went thru adding diff oils for recommended setup. Unlike like e-buggy the internal set screw for gear pinion was secure with loctite. Did some test laps at track, handles great with plenty of motor, with a good attitude off jumps. Most manufacturers will skimp on parts on their rtr’s but not with Serpent. Transmitter is not race ready, but would be ok for bashing.

Serpent S811T-E "Cobra E" RTR 1/8 4WD Electric Truggy
Very happy with my purchase & the item I bought, the only upgrade I'm going to do is to put on a better steering servo but otherwise the Serpent Cobra etruggy is an excellent vehicle.

Serpent S811T-E "Cobra E" RTR 1/8 4WD Electric Truggy
This thing is very well built, center diff housing is aluminum and I like that the spur gear is also metal. Tested on a backyard track and it handles awesome. Running 2 ecopower 30c 2c batteries and it's bad fast. Little disappointed in the radio that is included but the rest of the truck is so impressive I'm still giving it 5 stars. Steering servo is also plenty fast which was also impressive and makes the truggy easy to drive. Serpent has this thing dialed!
