I was very happy with the performance on dry rocks during the rock race. They gripped MUCH better than the All-T's and after the first course I had the second best time as well as being the only 2.2 to climb the bonus line. However, when the snow started falling and the rocks got covered in mud I was unable to climb one section that I could when it was dry. Many of the supers running Moabs couldn't either though. I had a hex slipping in the wheel so that may have contributed to the problem, not sure yet. Wheelspeed is still helpful with the RR's. Here's the bottom line. I was running an 8 pound rig (2 subC packs for 14.4V), a 16" wheelbase (a little longer than I think I want with these tires), and it was cold and snowy the first time I used them. I can not say yet if they will work good or not. I am going to continue to run them in the winter series and see what happens. My impression thus far is that they are superior to the All-T's, I'm just not sure if they will crawl up stuff as well as Prolines. Quote:
Yes, Pede fronts make for the widest track. I narrowed the wheels by moving the outer bead in. The width before narrowing was about 13" and after narrowing the wheels to 1.25" wide, the overall width is 12.5". I actually didn't want to narrow the overall track but I didn't think about that when I did the wheels. But since the RR's are pretty narrow it may have worked out for the best. I really miss the coil setup too, I really liked the look and it performed pretty well. I wanted to do it at least on the rear with this one but with the servos on the axle braces instead of on the side of the gear case I can't do it. | ||||

Update: I shortened the wheelbase to 14 3/4" it has 13 tooth pinions front and rear from the rock race setup switched to 1 6cell sub-C pack for crawling and painted up a new SuperDuke body for it. At the 1st Colorado Winter Series event things went great for The SuperDuke. I entered it in the super class and took seventh place out of 23 rigs. On course 1 I pulled up to the first ledge and the tries spun when I tried to crawl it. Of course all the comments about the Imex tires started coming out. I backed up a little ,gave it a bump, and it went right up. The SuperDuke then proceeded to rip right through the course, in Bender's words "crushed it" , and matched the lowest score of the day (-4). Course 2 and 3 went well also. I would have finished in 4th place if not for a stupid driver error of running over a cone on course 2. So far I am really happy with how it is working and don't plan to change anything for the next comp. The 13T pinions give it good wheelspeed even with the 7.2V pack. It's still early to make a judgement on the tires but at this point they are certainly exceeding my expectations. Thanks for the replies guys.

Looking good Griz, good luck w/ the RR's. I tried them for a few comps and now I'm back to Mashers. They just wouldn't bite on the slick rock we crawl here. Last edited by dezfan; 01-18-2007 at 10:27 AM. |

We have a secondary crawl local that has rocks that looks similar to the texture of the rocks in your pic. The RR's do pretty good on that type of abrasive surface. That could be the difference. |

Dang Griz, the SD looks pretty sweet, but where is the winch? I like the new lid.

With the current chassis there is no place for a winch right now. Once I decide on a wheelbase I plan to make a chassis that will allow me to run the coil spring rear suspension and a winch on the front. Just to keep it more true to the original. When you comin to Colorado? | ||

Truck looks great man! I definately like the "classic" paint scheme as well. Any updates on that front steering yet? If you are going to sell them, I want one for my Super! Very interesting design...would be great with my current setup. -Destroyer |

I don't run weight in my wheels as that takes away from wheelspeed. I run six 1/4oz stick on wheel weights in each steering knuckle. They fit perfect betweenthe knucle and the wheel. You can see them in some of the pics. Quote:
I'm trying to decide if I should optimize the design with some computer modeling or just make them like they are. The steering arm works great but there is always room for improvement, however if I don't get on it someone's gonna figure out what I did. Quote:
Thanks guys. | |||||

I have always said that stall can be controlled. Mismatched front/rear pinions, or how about my Laser4, and dual SuperRoosters. J/K | |||

To see this rig in action was a treat. It was a few weeks ago @ the rock race @ Kris's, and I'm sure there's been some changes other than the new body....but it was pretty impressive. Was the 1st time I've seen crawlers in action up close and personal, but this one really stuck out. |
