I would love to know peoples opinions on the different Gearhead Motors.

I’m thinking of getting 4 GHM-12’s for a rover I want to make or buy.
But I wanted to know about the differences and pros & cons between the two types (spur and planetary).
Opinions and other info would be great!

Thanks,

Steve
