Tamiya 70228 Arm Crawler - 2-Channel Remote Control

Controlled Crawling
This assembly kit creates the Arm Crawler, which features two body tracks and two arms that rotate to grip slopes and raised surfaces, helping propel it over obstacles.
Included 2-channel remote controller gives independent control of left and right tracks via the twin motor gearbox.
Take control of forward, reverse and turn movement!
Requires two R6/AA/UM3 or R14/C/UM2 batteries (sold separately).

Model Motion
Key to the motion of the model are (as the name suggests) its track-equipped arms: not only do they grip the surface and propel the model along, they also rotate independently, which allows them to match the surface angle and even haul the Arm Crawler over obstacles up to 45mm in height! A stay at the rear of the model helps prevent it from flipping on steeper slopes, etc.

Specifications
Maximum dimensions (approx.): 190mm length, 154mm width, 40mm height.
Type 130 motors are housed in a clear twin motor gearbox to let you show off the model's mechanics!
Includes everything needed for easy snap-fit/screw-together assembly. Simple wiring is required to complete the process.

Separately Required Items
R6/AA/UM3 batteries x2 or R14/C/UM2 batteries x2
