"I took this buggy to my local track where I've been racing for about 8 months, and laid down one of the best laps ever. This ready-to-run is actually ready to run. After proper break-in of the engine, even with a non-competition 'pullstart' powerplant, it's plain to see this chassis is legit. Serpent does offer upgradeable parts that are a definite upgrade, but not needed... I definitely recommend this for anybody who just wants another buggy or is just getting into the sport and not ready to build a kit. This is for you..." - Estill - Verified Owner

About the SRX8 RTR


Powerful Engine

The Serpent .21 pull-start engine proves to be an ideal match for the SRX8 buggy. Its exceptional quality, high performance, easy starting, and extended runtime make it the perfect choice for those entering the racing scene. Securely mounted on machined aluminum engine mounts, this engine ensures stability. The low placement of the foam dual-action air filter, snugly fitting next to the fuel tank, enhances the car's profile.

Differentials

Featuring Large Volume Differentials and oversized gears, a crucial aspect includes high-volume, large internal gear differentials. The internal gears boast an impressive Mod 1.25, marking them as the largest in the marketplace. With a robust hardened spring-steel diff-coupler of 13T and a connector running in 2 oversized bearings, the Cobra-E employs a 13T/44T gearing and a 46T central spur gear with a 13T clutch bell. This drive ratio ensures remarkable acceleration, complemented by the vehicle's low weight.

Performance Suspension

The suspension has been built to ensure that this buggy is at home either on the track or out in the park. Large, 16mm shocks are coupled to 4mm shock ends to give you super smooth and durable dampening. Sway bars found front and rear are designed to have little friction while providing incredible stability.

Features

  • 3mm chassis plate
  • Bumper aligned with chassis kick-up for precise landings
  • Composite chassis stiffener front and rear for extra stiffness

Serpent SRX8 RTR 1/8 Nitro Buggy w/2.4GHz Radio & .21 Pull-Start Engine
This is a step up from ANY RTR nitro buggy, it's high end all around honestly, kind off between a race kit and a RTR package.

The engine is alright, it's (based in my experience) a force .21 pro, nothing fancy but it has some power for sure!

Electronics are meh, but work.

This thing rocks out of the box, the suspension is kit quality, the driveline is basically set as a high end buggy. You name it, this is the best RTR option period!

This buggy is built like a race kit. Very happy with purchase. I have broke the engine in with no issues. This is my third serpent rtr and all are great. This is far the best rtr nitro buggy on the market.

I’m very happy with this serpent nitro buggy rtr. It’s perfect for someone who wants to learn and try nitro out on the track. I took it out to thunder alley and it handled well on the track I do recommend upgrading to the srx8 pro parts along the way

Serpent SRX8 RTR 1/8 Nitro Buggy w/2.4GHz Radio & .21 Pull-Start Engine
Bought 3 of these buggies for my boys. The cars are a nice quality for being RTR kits. The best part is the all the normal SRX8 Cobra Pro parts and option parts will work on this car. The electronics will most likely need to be upgraded if your goals is to hit the track. All the servos work just fine, but with 3 cars we noticed some variations in speed across the fleet. I would still get these kits for new racers. A solid 8/10 for an RTR kit!

Serpent SRX8 RTR 1/8 Nitro Buggy w/2.4GHz Radio & .21 Pull-Start Engine
Hands down the nicest RTR nitro buggy out right now.
The kyosho mp9 has a better transmitter.
But the Srx8 buggy itself is very nice.
Lrp needs to take notes and go back over the Rebel BX3.
Good job Serpent for paying attention to detail and providing a quality product!

Awesome value. Engine is strong and fast. Only upgrade needed is larger flywheel to use starter box. Servo's strong as hell

Serpent SRX8 RTR 1/8 Nitro Buggy w/2.4GHz Radio & .21 Pull-Start Engine
For starters, the glow plug was bad from the box, couldn’t even break it in because it would not stay running. Wouldn’t hold a tune at all. Absolutely no Info on what type of glow plug to use, no instructions for the motor at all either only reason it’s getting three stars if for lack of info, Once I changed the glow plug it ran amazing. Definitely change the servos and radio system if you wanna keep up at the local track.
Buggy us build tough that’s for sure. Hitting a huge double and slamming in to the back of the down jump and she kept on going, land nose first, yup, she cartwheels and kept going.

Serpent SRX8 RTR 1/8 Nitro Buggy w/2.4GHz Radio & .21 Pull-Start Engine
Had the hardest time starting the buggy, I tried and tried with a preheated engine with no luck. I ran bones brew break in fuel, I eventually tried a new glow plug and it finally started. So Bad glow plug right away! Check everything screws, set screws anything metal on metal. I forgot 1 set screw on the throttle slide, because it's not visible unless you take the motor off completely. So I had a runaway nitro, unfortunately it runs like crap so I was able to grab it right away lesson learned. Can't use a starter box unless you have the low profile motor mounts which those are sold out across the 7 seas. Pull starter as well sold out! So many bad decisions on this buy unfortunately, hopefully I can get it running properly. Wish I would of built my own nitro kit for racing instead of the serpent xr8 rtr definitely not the way to go if your racing. Any pros I don't think so I'll have tons of money into the serpent before its as strong as a kit or as fast. Cons: tires, tread pattern doesn't match one tire tread runs the wrong direction. Electronics are pretty dang awful, both of the servos failed right away. Servos made it through break in process but failed on the track right! Upgrade parts are very expensive and are not available like the low profile motor mount which allows you to use a starter box. Pull starter sold out! C Pins for the a arms need to be checked carefully every run.
Body was in tough shape!
Runs awful and very loud compared to any race kit version buggy. Would not buy again. Unfortunately! Needs spare parts 100% before you go racing doesn't look like it'll take a beating! Electronics need to be replaced 100% if your serious about racing then so does the engine you need a starter box much easier and more reliable than the pull starter. Do yourself a favor buy a kit version you'll thank me later.
