VEX Pro Parts Feedback, 2015

I wonder if a dual ball bearing supported VP output option would be useful for teams. Pretty much every VP failure I've seen is from excessive combined loads and VPs are just one of those things that teams tend to abuse. Most industrial planetaries of similar size like the Neugart PLE series are dual ball-bearing supported from the factory.

They are dual 15mm ID deep groove ball bearing supported on the output shaft.

The weak spot in the VP output is the snap ring holding the output shaft in place. For most loading conditions this usually doesn't matter, but with pull out loads generated by lead screws the snap ring can fail due to pull out.

The Industrial versions of these type of gearboxes all have the last stage of the planet carrier integrated into the output shaft so they do not have this same failure mode.

Used too many VexPro products to count this year, especially bearings and gears, and I can't think of a one that failed.

My only need this year that wasn't available was a longer hex shaft option for a VP...perhaps an extra-long ThunderHex version?
