Heh. Our drills didn't even last until they were out of their box in the kit!
When we took them out of their boxes, the transmissions fell apart all over the floor. All we did was lift it out of the box. It's no wonder we didn't use them in our drive this year
Actually, I think I've underestimated the drills a bit.
Anyway, If used correctly the drills/transmissions should last you a while...hopefully
There were so many teams that broke the motors or stripped out the gears etc. at VCU last year. They brought out buckets at the end of the regional of parts people had turned in broken. People could take the parts to keep. Both buckets were full of drills and drill transmissions. One BIG problem with the motors is if they overheat, the plastic connectors at the base will melt. Well, those plastic pieces happen to be the only thing holding the motor's brushes into place. Or if you take a hit and it breaks off, bye-bye drill motor.
I think if they perfected the drills so they weren't so flimsy (all the plastic housing) people would feel better about using them. It takes work and perseverance to preserve them well.
As far as your motors are concerned I think most of it has been covered in the previous posts.
