Alternate (Non-KOP) FP Gearboxes

[pfreivald]

I'm curious what other teams use as COTS gear boxes for their FP motors?

Andymark has one planetary (that apparently requires a pinion swap) that doesn't have that much of a reduction, as well as their GEM planetaries (which you could stack ~4 deep to get a 181:1 reduction.)

We're looking at possibly using the FP to run a screw drive arm lift, but don't have a lot of experience playing around inside a planetary gearbox, so we're looking for (hopefully) a COTS solution.

Any help would be appreciated!
