An idea to be tested for sure. Thanks again, Arthur, for your efforts to help your fellow FRC mates!
If you are using two motors, what if you use a two DPDT switches: one reverses one motor to drive it downwards, and the other switch shorts the leads of the second motor to provide drag. We 're probably going to experiment with either partial reverse/motor short or full motor short this week on our Minibot prototype.
