Speed usually costs money. In the RC world, hitting 100mph typically requires a $1,000+ investment in a Traxxas XO-1 or Arrma Limitless.
Rlaarlo is changing the math. They are a direct-to-consumer brand disrupting the hobby by offering carbon fiber chassis, brushless motors, and insane aerodynamics for under $300. But is it too good to be true? We tested their flagship speed runners to see if they hold up or fall apart at high speed.
Quick Summary
The AK-917 Supercar
This is Rlaarlo's masterpiece. A 1:10 scale on-road supercar that comes with a carbon fiber chassis straight out of the box. It is stable, aerodynamic, and ridiculously fast. For the price, nothing else competes.

The flagship. Designed for straight-line speed runs. It has adjustable aerodynamics and can handle 3S-4S LiPo power easily.

The best all-rounder. Small, durable, and very fast on dirt or grass. Perfect for "bashing" (jumping and rough driving).

A carbon fiber monster truck? Yes. It's built like a tank and designed to take massive jumps without snapping the chassis.

In the RC world, you usually have two choices: Cheap plastic toys (Amazon brands) or expensive hobby-grade cars (Traxxas/Arrma).
Rlaarlo sits in the middle. They use Hobby-Grade materials (Aluminum, Carbon Fiber, Metal Gears) but sell at Toy-Grade prices.
Unboxing: What's in the Box?
Core Features
Deep Dive: Build Quality
The standout feature is the Chassis. While competitors use flexible plastic, the AK-917 uses a rigid Carbon Fiber plate. This prevents the car from flexing and becoming unstable at 60+ mph.
The suspension arms are thick composite plastic, designed to flex slightly during a crash rather than snap. The shocks are aluminum and oil-filled, dampening bumps effectively.
Speed Test: How Fast is it Really?
We put the AK-917 to the test with a GPS speed meter.
The Controller
The included transmitter is "Okay." It has foam grip and adjustments for steering trim and throttle rate (great for limiting speed for kids).
Rlaarlo vs. Traxxas
| Feature | Rlaarlo AK-917 | Traxxas 4-Tec |
|---|---|---|
| Price | ~$200 | ~$350+ |
| Chassis | Carbon Fiber / Metal | Plastic Composite |
| Top Speed | Faster (Brushless) | Slower (Stock) |
| Parts Support | Online Only (Slow) | Every Hobby Shop |
Modifiability & Upgrades
Battery Life & Runtime
On a standard 3S 2200mAh LiPo battery, expect about 15 to 20 minutes of aggressive driving. If you are just cruising, you might get 25 minutes.
Note: The included USB charger is slow (3-4 hours). We recommend buying a proper balanced charger (like an IMAX B6) for faster, safer charging.
Unlike Traxxas, you cannot walk into a local US hobby shop and buy a replacement arm for a Rlaarlo. You must order parts from their website, and they often ship from China (10-15 days).
Recommendation: Order a "crash kit" (extra suspension arms) when you buy the car so you aren't stuck waiting.
Pros & Cons
- Insane value for money.
- Premium materials included.
- Very fast straight out of the box.
- Excellent body aesthetics.
- Parts take weeks to arrive.
- Manuals can have errors.
- Stock tires wear fast on asphalt.
Who Should Buy This?
- The Speed Demon: If you want to go fast on a budget, the AK-917 is untouchable.
- The Tinkerer: If you enjoy upgrading and wrenching on cars, this is a great platform.
- NOT for Young Kids: These cars are too fast (60mph+) and can cause injury or break easily if crashed into a curb. Stick to slower crawlers for kids under 10.
Frequently Asked Questions
How fast is the AK-917?
Out of the box with a 3S battery, it can hit 60-70mph. With upgrades, it can exceed 100mph.
What happens if I crash?
You will likely break a suspension arm or bumper. You can buy replacements on the Rlaarlo website, but be prepared to wait for shipping.
Are they waterproof?
Most Rlaarlo electronics are "Splash Proof." You can drive through puddles, but do not submerge the car.
RTR vs. Roller?
RTR includes electronics and remote. Roller is just the chassis. Beginners should always buy RTR.
Final Score: 9.0/10
Rlaarlo offers champagne specs on a beer budget. If you are an intermediate hobbyist who wants a carbon fiber speed runner without spending $600, the AK-917 is a no-brainer.
