I am not quiet sure if i understand the "radial load" part (i am quiet good at physics, just not in english...), but these really help a lot.

I'm currently trying to build a feather spinner, but since the next event might be before i am ready with that, i'm also considering using parts of that (mainly the esc) for a raptor pusher/wedge/something like that. Something smaller and simpler i can definitly finish in time, and your gearbox/motor-combo seems to be a nice solution for that.

So now i have to think how many motors i could use with my 40amp esc (it would handle both sides, so 2 or 4 motors). It could possibly handle a bit more than that for a short time, but got a fuse for 40amp, so... don't want to risk it.
Seeing those ratings... even if a real "stall" doesn't happen too often, i think just two of them should be enough.
I'm gonna do a bit more thinking and possibly placing an order the next few days... maybe i just order 5, do some testing and and either got 3 or 1 spares o.0
