1:8 EP Crawler CR1.8 “Yucatan” LIME-GREEN RTR

    

Portal axles not only offer a greater distance from the differential housing to the ground than conventional axles, they also have another positive feature. In conventional crawlers, torque applies so much force that the vehicle jumps over the obstacle. The design of portal axles reduces the gear ratio at the wheels and virtually eliminates torque shocks from the drive. The overall reduction ratio of the axle drive is more than double that of non-portal designs to ensure smooth running.

A unique hydraulic steering shock absorber design combined with a 20kg (actuating force) digital and waterproof steering servo with aluminum servo arm allow a steering angle of up to 43°.

      

3x 0.9kg mini servos for the 2-speed transmission and the differential locks/unlocks are already installed. All servos are waterproof.

     

The YUCATAN Crawler has a 2-speed manual transmission that lets you overcome difficult terrain and also get to the next obstacle quickly. Simply press a button on the remote control and switch from the standard 1/37.1 (low-speed) to 1/15.1 (high-speed) gear ratio.

Lock and unlock the front and rear differentials independently for maximum performance on the track – all controlled remotely with your radio and 2 built-in mini servos.

Leave the differential unlocked for smooth handling at high-speed. On technically challenging trails, you can lock the front differential, the rear differential, or even both to handle extreme terrain.

            

An aluminum motor mount and adjustable slipper clutch provide added protection in extreme conditions.

     

 Hardened steel differential gears and drive parts – designed for high loads.

The drive concept – powered by HOBBYWING – includes an 80A (440A peak) waterproof speed controller and a 775 motor.

With an optionally available program box, 15 different parameters can be set:n:

Run. Mode / Bat. Typ / Initial Start Force / Max. Forward / Max. Reverse / Max Brake / Drag Brake / Drag Brake Rate / Neutral Range / Punch / PWM Frequency / BEC V / Freewheeling

The battery box has the dimension of approx. (L/W/H) 160x48x25mm and is thus designed for 2S or flat 3S LiPo batteries which also corresponds to our recommendation.

In 3S LiPo battery operation +30km/h can be reached! Thus, this crawler is probably the fastest off-road vehicle of its kind.

ATTENTION: The speed controller is also “4S LiPo” capable which we absolutely do not recommend! The vehicle (gearbox, axles…) is exposed to extreme force transmission in 4S operation. Also the handling of the crawler deteriorates with increasing speed which can lead to accidents and costly damage (no warranty claim).

The 6-channel 2.4 GHz radio system gives you total control over your vehicle – whether it’s the light unit, 2-speed transmission, differential locks or setting the top speed.
