Novak Eiger Crawling ESC/Terra Claw Brushed Motor Crawler System (55T)


This is the Novak Eiger Crawling ESC/Terra Claw Brushed Motor Crawler System with a 55 turn Terra Claw motor. The Eiger mountain towers amongst the giants of the Swiss Alps topping some 13,000 plus feet. Let Novak’s Eiger 2S/3S Crawling Brush ESC power you to mountain-high adventures as well! The tiny Eiger is packed with all the features you need, and is easier to use and more adjustable than any ESC in its class. Tuning on the rocks is as easy as 1-2-3, with no programmers or wires to fuss with! With four on-board adjustments, the Novak Eiger Crawling ESC can be customized to suit any type of crawling.

The Eiger is compatible with 2S LiPo packs and has a built-in, heavy-duty 2-amp BEC that will power high torque single servo setups with ease. The Eiger is also compatible with 3S LiPo packs! Simply install an external BEC and enjoy the wheel-spinning good times of 11.1 volts! Yee Haw!


The Eiger comes ready to crawl, and will default to the normal rock crawling settings: forward and reverse with high-power drag brake. Not only can you adjust the power of your Drag/Hill Brakes via the simple on-board programming, but you can turn them off completely. This will set the speed control in normal “Basher” mode with forward, brake, and reverse operation -just like a regular, non-crawling ESC! It’s the best of both worlds. Crawling and bashing!


Novak’s affordable Terra Claw Crawling Brushed Motor, provides precise movement control, and exceptional torque and long-run times due to the motor’s high-turn count. Additionally, the Terra Claw is extremely durable, ensuring many smooth and maintenance-free crawling seasons.
