These are really nice motors and are very smooth. I am using them for a science experiment and they are working out great! The only thing about them is that some of the bullet connectors are not already soldered to the speed controllers leads. This just takes more time so if you want to plug and play, its not that simple. But these motors are defiantly worth your money and their name says it all. Great work Grayson Hobby!
