Scorpion Rock Racer 1/10 Rock Crawler RTR

Comment: This crawler is a good start for a competition crawler. However, if you want to get serious into rock crawling, you will need to have the front diff lock. after installing the diff lock it became a real rock crawler also it was very good driving it on sand dunes.
Overall this crawler worth the money.

Comment: First, let me say that this review is NOT for a Rock Crawler. I picked up this RTR version of Axial's wildly popular AX10 kit, and decided to make it a true racer.

On went a new Castle Mamba Max motor/ESC combo. I also switched out the stock pinion/spur gears with a 31T pinion, and 73T Traxxas spur gear for their Bandit.

I switched out the stock shocks with Traxxas "Big Bore" shocks, with limiters between the shock piston and shock body. I also used the softest springs I could find, as this set-up would be STIFF over jumps (hard on the chassis), but you get the torque twist inherent in this design (strangely, it looks like a dog wanting to shake hands under full throttle).

I replaced the tires with Proline "Flatiron" tires, and on went a new body, worthy of the title of racer. With a Spektrum transmitter/receiver, to "tailor" the power delivery, this little machine flat hauls! With it's FWD drivetrain, full powerslides around corners are easy as they come! It can't do wheelies because of the nature of the four link system, but this truck was originally destined for track duty, anyway. For this, a few tweaks are in order, as it's debut at the local track was a bit less than stellar, but the problems are easy fixes.

If you are like me, an inveterate tinkerer, you can build this racer from the parts listed above, available here, on Amazon. It's funny, Axial lists this crawler as a "Rock Racer", but the thing only goes about 8 MPH out-of-box. Not much of a racer, to be sure!

Comment: The scorpion rock crawler is a good start for a competition crawler. However, if you want to get serious into rock crawling, you will need to make some upgrades. I would suggest an all metal gear servo, steel controll arms and to install the locker for the front axle. I put in these upgrades right when I bought this truck from HobbyTown and they work great. I would also suggest adding sticky rim weights into the wheels and cutting the inner tire fome into a "gear pattern" to give you maximum grip. This crawler will climb up rock and dirt piles and over anything you throw at it. Overall I think axial did a good job with this product and I'm sure you'll enjoy it.
