I wish there was a robotics store near me so i could just test gears out and than buy the one that works best...
One last thing and ill can start putting everything together
here the tilting base:
I got it a home deport its suppose to be part of a heat duct i think. Its not very sturdy too if i use alot of force i probably could bend it in half. I may have to find something else because its 30 cm long and at the beginning of the competition a 30x30x30 cm box has to be place over it to see if it meets the length width and height requirement. The box might not able go over it. I''m trying to think of an alternative that's less than 30 cm and stronger.
Now my original thought was to mount a gear right here than have a some kind of stick running through the gear hole to the other side for support and have a gear on the servo to turn the gear mounted on the base. However you suggestion was to just use the servo... so the servo would be attached to one side wouldn't the other side need some kind of support since i am removing the bar between the sides. Although, I could see it work if i wasn't tilting 5lbs and their distance wasn't 30 cm away.
