Wow... impressive... you overcame static friction.
Torque is a function of rotational mass and acceleration. Just as long as you don't exceed 40 Amps, it's just a matter of finding a balance between momentum and top speed. When you find that balance, you can pull just about anything with wheels on it.
Every year I see teams asking, "Why didn't we get picked." They try blaming someone else by making it sound as if it's the responsibility of other teams to pick them, when in reality it is their own fault. I feel no sympathy for any team that does this. You should not rely on other teams to pick you. That is the purpose of seeding. The reality is that you seeded 65th out of 73. This could mean several things, including:
1) Your robot wasn't built for the game and/or broke.
2) You had a bad (inexperienced) driver
3) You had a bad (inexperienced) strategist
4) You didn't sell yourself well enough
