Everytime someone posts on these forums "never use the drill transmission! They blow up all the time! We destroyed 80 kabillion of them!"
I wonder: "What the HECK are you guys doing to that poor gearbox?"
Personally I hope we see it back in the kit.
(I know everyone thinks FIRST has ruled them out, but I'm still waiting for the OFFICIAL confirmation, not this speculation stuff, that they're not coming back in 2005.) The drill and tranny (when not used for drive) make an EXCELLENT high powered mechanism motor. Lots of power, lots of reduction, small package.
Seriously,
3 competitions, lots of severe shock loading, no problems.
What are you guys doing wrong?
What am I doing right?

Yes I know that some teams had no problems with them that is because 2 years ago there was a mass defect in the coupler assembly line and I know my team and many other teams got defective couplers which where not drilled and taped straight. This caused the drill transmissions to torque up and down sheering the casing. This was the problem I know my team and many other's had. Because of this there where some people who got good couplers before the defect in the line happened. But those are few and far between. I have no problems with the actual drill motor or actually the transmission but those coupler's. And since you can't attach the drill transmission easily to a shaft without one it makes the drill transmission almost useless.
