- Manual & Decals: Full color owner’s manual with info on the car and electronics, has all exploded views for easy parts-finding and detailed list with spare parts and optional parts. Decal-sheet with Serpent and 411 logo’s are included as well.
- Packing: The 411 RTR comes in a strong carton box with full color printing.
- Optional Parts / Upgrading: The Serpent 411 Sport is based on the high end race version of the 411. All parts from the 411 race-version and also the optional parts fit the 411 Sport.

1. There is silicone based lubricant spewing from all corners of the car, inner body, spools, diff casing........etc. After your first run, the car was a nightmare to clean as dust and pebbles stuck to the chassis and surrounding parts like glue, and this was after cleaning off as much lubricant as possible.
2. Rear pulley spacers were both slack. The smooth functioning of these pullies and spacers is extremely important as both shorter and longer drive belts hook up to it which in turn drive the spur gear. Therefore if there is play on either side, it causes vibration to the spur gear which translates to vibration to the drive system. The end result was damaged spur gear teeth, pulley teeth and a shredded short drive belt running from the rear diff to the pulley.
3. The plastics mounted to the kit are extremely soft! You have to be careful not to ring out when tightening grub screws, hex screws. With the slightest bit of torque I was able to ring out both servo mounts.
4. Hex screws are equally brittle
5. My biggest beef is that of the ball joint linkages that give you your caster adjustment. They affix themselves to the uprights that house your bearings, c-hubs etc. This came loose just from running in my yard, 1/4 throttle, no accidents, again it might have not been properly tightened.
Im no ranter........... this rtr is very poorly assembled, it makes no sense at all to put a product up on the market as a ready to race version and the user has to run through the car piece by piece to find the loose ends and damaged parts as a result of the poor assembly and inferior plastics used. If I were a child, this car would be in pieces by now as its not a car you can put on the ground and go! It has to be carefully inspected.
Buy this rtr at your own risk, I have its bigger brother serpent cobra gte 1/8th scale.............ZERO problems. None. Well built, zero issues. If you must buy, buy the ERYX KIT.
The car is not that fast out of the box, but that was due to the slow gearing, easy change.
One complaint, the wheel nuts were cranked down so tight, it split all four wheels and crushed the plastic wheel drive hex's, I planned to replace them with aluminum anyway, but would have been nice to at least get some use out of the wheels and tires.
Overall, great car for the money ! I would certainly recommend it !
Update. After a few runs and going over the car, I must say Serpent quality control on this rtr needs some big time help. I found both rear hinge pin retaining screws to be missing, one side of the steering setup was missing a spacer that didn't allow the screw to tighten in the receiver which caused massive play in the steering not allowing the car to track straight, one of the top plate hold down screws was overtightened and stripped, and a few other minor things. I still really like the car overall, would just recommend a thorough going over of it before running.
I looked over the car prior to driving it the first time. All screws were snug, and belt tension was good (Relating to a YouTube video on tension/deflection). We took the car and a handful of cones to the city park basketball court early one AM, and were packed up and headed home 10 minutes later. On the steering link, one of the ball screws (Well, a screw into a ball) had come out and gone away. The front belt had stretched quite a bit, too, but maybe this is typical—I will figure it out with time.
I pop into Amain to order more “Uni Pivot Balls”, and WOW $16 for a pack of 4! Steel ball screws from AE or TLR or Tekno don’t cost that much. Plus, without special pliers (Since there is no room for shock shaft pliers), you aren’t going to be able to hold the ball during tightening or loosening (Since they are going to receive a dab of loctite now).
I have only skimmed the usb stick manual that was sent, and don’t see anything about belt tensioning adjustments, right off hand. Thank goodness for YouTube videos.
Finally, for a RTR, and this is only opinion, I think the 3600kV motor is too fast, especially with most classes around me being 25.5/21.5/17.5 based.
It is a very good model to start in the hobby. Good quality and price.
I used it for a while, right now I’m running two ARC in 17.5 and 10.5
I just wish it would have come with a sticker sheet... ...because yeah... i buy stuff for the stickers!
There are hop ups availables from Eryx 3.0 and options to different set-ups.
Competition shock absorbers.
The electronics are enough for you have fun in a rc track.
Semi pro rc car for a great price.
