Re: Banebot 56mm gearbox - double D - RELOADED

Probably not. This would help the gearbox and motor run smoother, but it will transmit torque as well or better than it did before, meaning the double-D could still deform over time.

Update on the tempered C40-hardness A2 tool steel carriers: We finally got around to re-mounting and testing today. The HS kids enjoyed the opportunity to do wheelies and driving it like crazy in a confined area. After about 5-10 minutes of driving, a sprocket bolt fell off (somebody forgot locktite) and everyone suddenly had to leave instead of fixing it.

I wouldn't call this definitively tested, but they didn't fracture and there is no backlash to be seen right now. More testing to come tomorrow.

Our drivetrain is 1 CIM, 12:1, going to a 6WD. See attached pic.

Edit: Yes, I know the shafts aren't well supported. O_o
