I am using them at my minisumo (as usual). All opponent robots defeated easily. They hold the ground very well. And don't need to use any extra coupler, hub etc.. nice. I clean with alchol and voila! very slick traction.

This ebook opens a new page in my sumo robots. That made me notice many many mistakes. Getting help from a JSumo, for new projects also priceless.

Recommended!

When will be restocked? I bought last piece months ago and using. For my new project I want to buy more but still waiting. Please be fast Jsumo :)

I won Robofest 2016 Robot competition 2nd place with that chassis. Recommended to all project makers.

I liked the versatility. Gives low COG to robot. Only suggestion is why you don't designing similar chassis for 5 sensors?!

Better price than Pololu. We use it for line follower and mini sumo robots.

I am seeing this gear bundle at lots of Mexican robots, stop selling! :)

Very lightweight for sumo projects. Before this model, I was using nearly 2 times heavy gears (1 module) but with this combination robot's response time decreased (which is better) and no more sound like tractor, jejeje.

Motor's current slope is wonderfull. We were using old chinese motors which makes lots of electrical noises, resets... but this RE35s are completely insane. Very clean electrical interface. Same weight but power is nearly tripled! Just my problem is heating due to Arduino's low PWM frequency.
