Serpent S811T-E "Cobra E" RTR 1/8 4WD Electric Truggy
Excellent Right out of the Box! I had to bleed two of the shocks, and remount the ESC (the tape didn't hold). I notched the mounting tray to make some room for the ESC Signal wire. The ESC included will run Sensorless (included), or Sensored motors. (Nice!). The BEC is rated for 6V, 3A. I added a glitch buster (just in case) since I swapped out the servo for a Savox SB-2274SG. The included servo sould work fine for most people...but I wanted something quicker.
The stock transmitter/receiver, was pulled and put up on ebay....I never bothered to try it...however, a friend also bought the Cobra Truggy, and it worked fine for his first run on the track.
I've been doing RC since 1983...owned over 100 cars, and 50 airplanes......this one is a keeper.
Highly recommend.

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.

The car differential was messed up I never got to drive the car it was rye but I took it to lhs and they said the car was played with prior to me getting it to the mail. I will never order here again and I kind of lost interest in the hobby after wasting about 600 dollars!!!!!

Serpent S811T-E "Cobra E" RTR 1/8 4WD Electric Truggy
**UPDATE** EXTREME AMOUNT of thread lock on wheel hubs from factory!! Build up of loctite (blue) causing difficult wheel/tire changes. Slighty bent 2x front CVDs from vice grip pliers (was able to remove) Extremely bent 1x rear CVD (was not able to remove) Stopped as I don't want to break it. Will email and send photos to Serpent USA. Damages should not occur to truggy and very extreme force (muscle) should also not be required performing routine maintenance.
**UPDATE** Serpent America, Florida--GREAT CUSTOMER SERVICE! Emailed my problem, proof of purchase and photos. Shout out to Doug, Ricardo, and Joaquin for quick response and solving my issue. Parts mailed out next day. Anyone else has this problem STOP IMMEDIATELY and apply high heat to hubs..(I used my soldering iron & wedged into hex area & sit for 15-20 minutes to breakdown locktite) then 17mm wheel nut was able to be removed. ORIGINAL RATING *** After great experience with Serpent America *****

Handles very well, top quality materials used throughout kit,looks amazing, fast on 4s. First the wheels are extremely tight. Cannot remove & now both fronts possibly have stripped wheel hex? Cannot retighten either & now they're wobbling pretty bad. All 4 wheels are like this. I stopped trying once 1st rear wheel did same thing. Second, the plastic piece on lower part of aluminum body broke and shock went out on 1st run. This happened on 4s on moderate jumping in grass. Purchase was made
7/29/20. The shock doesn't concern me, stuff breaks in this hobby & is part of the fun in repairs and upgrades. But the wheels issue sucks because I can't run it (can run on busted shock) don't want to cause further damages from loose front wheels. I bought another set of wheels/tires to use for bashing and stock pin tires (excellent quality) will be used at local track. That's why I tried to remove wheels. I emailed Serpent America office in FL yesterday, maybe they can try to help in some fashion. I'll have to take to hobby shop, because I am beyond my scope of repairs. Also, wrenching on this is harder than expected. I've got AE, Tacon, and HPI electric & nitro RCs since 1996. But Serpent 811te is first rodeo in 1/8th. These are easy fixes but frustrating; wheels tightened by Thanos + threadlock at factory and can't remove is stupid problem to have. Don't let this rating scare you from buying! Get it, just don't change wheels/tires until absolutely ready. And the shock; chalk up as phantom hit...

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!

Serpent S811T-E "Cobra E" RTR 1/8 4WD Electric Truggy
Excellent quality rc!
Well bonded and all the parts are screaming quality and durability..
In 4s this thing is violently fast (accelerates like a bullet-top speed is nice)
In 6s is just not fun! needs a stadium to drive it safely..
All in all this is a super truggy.
I own the TLR 8T 4.0 and this RTR has almost identical quality with the TLR.
(From a fun perspective the TLR with my Novarossi ELITE 5 is more fun but the serpent kills it without hesitation: is faster and more violent and the part quality is the highest possible..)
If you find it, take it. This thing is FAST, DURABLE, NIMBLE and RACE READY for sure!!!

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.
