Re: Need advice on motors, gearboxes, and ESCs

I want to put in my 2 cents for the versaplanetary. See the attached spiral shaft (where the anodizing has flaked off). It wasn't meant to be a spiral, but a 100:1 versaplanetary followed by a 7:1 vexpro single stage managed to twist a 1/2" aluminum hex shaft into a twizzler shape. The planetary was undamaged. The motor is an RS-885, and that bronze bushing on the end on the versaplanetary output shaft is very important! We have used many banebots planetaries in the past, and I am pretty sure they wouldn't have all their teeth after this experience. Kudos to Vexpro and IFI!
