Re: pic: 2980 practice bot Climber

I think you can be almost completely certain that those gearboxes will not last you the entire season. I'm sorry to be the one to tell you this, but they are just not that strong and are not robust enough for this application.

I would recommend replacing them with a pair of Vex VersaPlanetaries, and using the JVN Mechanical Design Calculator to figure out a ratio that will allow your robot to climb well. I bet you can climb nearly 4 times as fast as this setup is geared for without much of a problem depending on the diameter of your winch and weight of your robot.
