This is a placeholder topic for [**“Dagu Wild Thumper 4WD All-Terrain Chassis, Black, 75:1”**](http://core-electronics.com.au/catalog/product/view/sku/POLOLU-1567) comments. ![](https://core-electronics.com.au/media/catalog/product//d/a/dagu_wild_thumper_4wd_all_terrain_chassis_black_75_1 __pololu_1567__ 00.jpg) This rugged, 4-wheel-drive chassis from Dagu Electronics has independent suspension for each of its spiked 120mm-diameter wheels, allowing exceptional traction over uneven terrain, and its body is made from 2mm-thick anodized aluminum with a 10mm-pitch grid of 4mm holes, making it easy to mount electronics and accessories to the chassis. Assembly of the chassis is a simple three-step process that takes just minutes. This model is black with 75:1 steel gearboxes on the motors. It might have metallic-red hubs (as shown in the main product picture) or gold hubs (not pictured). [**Read more**](http://core-electronics.com.au/catalog/product/view/sku/POLOLU-1567) ---

What would be a suitable motor controller with Raspberry Pi bridge to use with this product? ---

Hi David, A controller such as the [Pololu Simple Motor Controller 18v7](https://core-electronics.com.au/pololu-simple-motor-controller-18v7-fully-assembled.html) would be a good choice for a Pi since it can be sent commands via TTL serial. There are a few different options for controllers with and without feedback, just make sure it can handle the 6.6A stall current of the motors in the Dagu. Good luck with your project! -James ---

Thanks James! One other question on this product - do you offer the similar model with the 34:1 gear ratio? Thank you! ---

Hi OlSnacky, While we have retired most of the variants of the Dagu, Our supplier does stock the different variations, so we _might_ be able to special order one at an extended lead time. Send through an email to support@coreelectronics.com.au and we’ll see what we can do. -James
