So I got to wondering if I could make the Telluride into a respectable crawler. There are inherent limitations of course, but I think it may have a few surprises up its sleeve. One big limitation is the lack of crawler tires for wheels that will fit on the hub. For now I will stick with the Trencher SCs, but I may see what kind of tires I can fit on 2.8" rims. I'm hoping I can find a way to mount some true crawler tires on them--maybe even some real beadlocks.
For now these are the important mods:
1) VXL-3s powering a 24 turn Titan Marine motor with a 9t pinion and 54t spur. This offers outstanding torque and low speed control. Top speed was pretty pathetic until I added the 9.6v battery. Now it is probably back up to stock speed with 3x more torque on the low end.
2) Slipper clutch--you will need to upgrade this with anything other than the stock 12t motor. For now I'm still using the regular upgraded slipper clutch, though I may get the heavy duty unit eventually. I also think it's wise to get the aluminum bearing adapter for the slipper shaft. It will control wobble better. Much criticism has been levied at the nylon driveshaft. I don't know why. It handles all the torque I throw at it and I prefer it to the aluminum shaft. The aluminum shaft has more play. The nylon shaft is quieter and lurches less at low speed. Long live the nylon driveshaft!
3) I've replaced the turnbuckles and all camber links with the aluminum units. You need to trim about 2mm off the ends to use them as camber links, but they do give you more adjustable camber options than the factory holes.
4) I'm using big bore shocks for their improved smoothness and progressive rate springs for now. The progressives with the large pretensioners allow the truck to sit up a little higher for more ground clearance. They are soft enough to allow plenty of travel, but prevent you from bottoming out.
5) The Stampede 4x4 shock guards fit with a little bit of modification and allow you to push over rocks more easily than bare A-arms.
6) Today I put in a 2075 servo for more torque. If you are crawling over rocks or getting stuck in ruts, the extra torque will probably save you from burning out servos.
7) Trencher X SCs--these offer outstanding grip on most surfaces, but on a 2.2/3" wheel, they just don't have the kind of sidewall flex you need in a crawler. We will see how well they perform.
I've made a few other mods, but they were mainly just for kicks. The lights look awesome, but they don't like rollovers. They do light up the night though!
I hope to make some crawler videos this weekend. For now all I have are the pics.
Now get out there and start modding your Tellurides!
