[i]SCOTT: I think the wire wheels worked very well relative to traction. The only wheel slippage that we noticed occurred in hard turns at high rates where the momentum of the vehicle would keep it going straight until the speed slowed enough for the wheels to catch. One time we had the wheels spinning in the soil; they were digging in in opposition.
IRWIN: When we got to the ALSEP site.
SCOTT: Yes. As I remember, we picked it up and moved it to another spot and it worked fine. Did we just pull it out?
IRWIN: We just went in reverse.
SCOTT: That's right ...[/i]
... and later ...
[i]IRWIN: One time we did a 180; the back wheels just broke loose and they slid around.
SCOTT: Coming down the hill?
SCOTT: I think that was just because of the slope. We probably had most of the weight on the front wheels, and I had to make a turn to avoid a crater. There just wasn't much traction on the rear wheels. It was just a matter of going slow when you had obstacles, and catching up on your rate when you had a smooth field in front of you. I couldn't ask any more in controllability of the vehicle. It's just superb. I have no recommendations on any changes in the control system. The reverse switch works fine. The techniques we were taught in how to go into reverse and how to go into forward worked fine. We did use reverse several times. Aside from the fact that you can't see behind you -- when you can tell me which way was clear behind me -- I was very comfortable backing up. Like the time at the ALSEP site -- there was no problem.[/i] [/B][/QUOTE]
