[Aren_Hill]

We (1296) did end up trying a swap to 9:1 from the 7:1 is was running at, but decided to stay faster.

We did TIG weld the pins into the carrier, and ream out the planet gears for needle bearings.

Overall it was 12:48 via a 3mm gt2 best with WCP pulleys, and then 7:1 and an Integrated encoder, direct driving a 6" wheel from WCP.
Gearbox was fine, rode a bit too close to the sun speed wise with the motors.

Would I recommend this to most teams? nope, but being as familiar as I am with the system the Crew and I gave it a whirl.
