The Arrma Limitless 1/7 Scale Speed Bash Electric 4WD All-Road Roller was developed to perform in any condition. Loose gravel, asphalt, or short grass, and in the sun, rain, or even ice. The limitless is battle-hardened and features a customizable aero-package that will allow you to tune the balance for pure performance.

In addition to the low drag LIMITLESS body, which comes pre-trimmed and decaled, Arrma has added front and rear wings that can also be customized to tailor the downforce to your preference. To further enhance the aerodynamics, the chassis design includes a front splitter to balance downforce distribution and a rear diffuser that increases downforce and grip, enabling you to corner faster and with the proficiency needed for a hyper speed platform.

!!!WARNING!!! Recommended for experienced drivers ONLY! 
This model is capable of an incredibly high rate of speed, and it is not recommended for inexperienced drivers. Previous experience with high-power radio controlled models is highly recommended. This model is not intended for use by children or minors younger than 16 years old. Individuals younger than 16 years old require responsible adult supervision during operation and maintenance. Additionally, when driving this model up to a 1/4 mile of traffic free, uninterrupted driving area could be required. The space in which you choose to drive should based on the setup of the model, and the potential top speed of the car. 

Underneath the aerodynamically engineered body is a 3mm anodized aluminum chassis with a full length center brace for maximum strength. The heavy-duty 4WD drivetrain features durable steel drive shafts plus all-metal diff outdrives and gearbox internals. The diff module can be removed by removing just four bolts, helping to simplify maintenance. A sliding mount makes motor access quick and easy, too. Big bore oil-filled shocks on black-anodized front and rear shock towers keep the dBoots Hoons all-road tires hooked up for maximum traction. The tires are mounted on speed wheels with extra-durable hubs.

I received item early & wasn't disappointed. I've been/will continue ordering thru this site until service declines. I don't foresee this being an issue. ??

If you’re looking for a ultra-high speed basher, this is your model. It’s huge , with a great looking body and fast. I installed a Castle Creations Mamba 6s drivetrain, and a couple of protek 3s batteries. It hauls. Having tons of fun with the Limitless, highly recommended.

Exceptional quality of a roller. Tested on speed runs and the Limitless was very stable at high speeds with everything stock!

Some minor issues include:

1. Differential cup grub screws are loose despite the blue loctite applied on them. (production assembly error maybe)
2. Some hex screws are extremely tight that when you torque it counter clockwise, the hexagon in the screw head easily gets deformed and becomes round, therefore, you won't be able to take it off.
3. Body stickers are off the line, some are not applied well maybe due to production mishaps.

Nevertheless, still 4.8 / 5 stars from me.

Arrma Limitless 1/7 Scale Speed Bash Electric 4WD All-Road Roller
Looks great, like a real F1 Car, Only came with the high speed gearing pinion, and as a result until i can get another smaller pinion i only get a short 5 - 10 mins runtime (2x2S 75c batteries), before i experience overheating issues and my Mamba Monster X ESC says there is motor start failure issues. if possible i will write another review once i am able to run out a full set of batteries, however i am not dissatisfied with the purchase, just wished for a smaller stock pinion aswell as the optional high speed one

Hey I apologize for the bad review of Hobbytown. After talking with one of the customer service members. I understand why the stores are getting these kits first. If you don't want wait try checking your local stores. I actually found one they get there orders first . Excited to check this kit out will write a review after it is assembled and running. My Bad. Car is fun running a 2200 kv Castle system. Pay attention to your motor temperature the stock gearing is for high speed straight line runs. If you just want to bash bigger spur and smaller pinion. Then it will perform and is a blast. 64 mph 4 wheel slide through the corners and very controllable. Website says it is in stores check your local stores. Good luck and have fun when you get 1.
