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.
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!
OWNED IT FOR ABOUT A WEEK.I GOTTA SAY ITS ONE HELL OF A TRUGGY! I OWNED A LOSI EIGHT T 2.0, AND THIS SERPENT BEATS IT HANDS DOWN! GREAT QUALITY AND ITS A BEAST ON 6S!
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.
**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...
Reviewers broadly praise the Serpent S811T-E Cobra E truggy's speed, handling and build quality, especially on 4S and 6S power, though several note it runs hot and is violently fast on 6S. The most common criticism is the included 2.4GHz radio, which many say differs from the advertised model (e.g. ESC or controller variants) and in one case would not bind. Recurring quality-control problems include leaking or poorly filled differentials, loose screws, flat-spotted tires, bent driveshafts or CVDs, and a sagging rear end from soft shock springs. Several owners report good customer service from Serpent USA and AMain, while others report slow or no replies. Reviews are mixed on durability, with some owners reporting repeated differential and shock tower failures.
