Default Tube Project 10/10

There, I went and said it. Now I'm committed



...currently poking around the net for some 1:1 moon buggy-type layout ideas. 2.2 class comp rig. Have Pede trans ordered. 84Spur / 18Pinion?

The rest of the pics

i run an 87 16 in my pede... but with a lathe motor im sure you will have enough torque in just about n e gearing...

My crawl ratio is 39.54 : 1 - I have a good ammount of wheel spin but TONS of torque...

and with an 84 /18 it would be
33.94 : 1

It is a 14 % loss in torque but a 14 % gain in wheel spin ...

And if you wanted ULTRA torque... you would go with a 87 spurr and a 9 pinion with a gd 600 (2:1) for a crawl ratio of 140:1 a snail could woop the crap out of it in a drag race!!! The truck with a lathe motor would go a woppin' .83 MPH with a set of mashers.... OHHH YA

Nice rig tho im lovin that SUPER ULTRA HIGH MEGA NON EXISTANT GROUND CLEARANCE!!!


ohhh and thoes plastic 'bearings' trash them... invest in some real bearings...

I like your idea of mounting your axles, only thing is the blocks might get in the way when you try to dial in the link setup and shock placement.

Since you've seen mine crawl, I'm running 84t/12t with lathe motor.

Now if we could just get sean and kenn to build tlt's. To me, they're funner then the clod to drive.

i like the idea of mounting the axles during the chassis fabrication. I've seen it done many times in the 1:1 world with a chassis bench, i dont see why it never clicked to do the same here. keep us updated.

... Yhea, I knew you guys would be all over me about the ghetto plastic bearings. I do have bearings on the way

So what's the smallest pinion I can run with the 84 Spur on the Pede trans? Sounds like I need to gear down some... Will be running a 55t lathe motor.

...yhea, I like your gear ratio Jeff. I'll try the 12t pinion first and see how she goes.

I want to build it to UTRCRC spec, so I thought it would help to have it all layed out at 12-1/2" wheelbase while I try and braze up some tubage. Just need to get the trans here so I can bend the pan and go from there. Need some thin ss sheet too...

I went for the moon buggy look. Mine has a 13 inch wheelbase. Ive heard that next years wheelbase will be 13 with utrcrc. I set up my tranny and axles as I built the frame. Then I had to make everything else fit. After getting it all in I made the frame look like I wanted it to. So far Im really happy with how it crawles. I ran long shocks on the front and short ones on the rear. That made it very stable. I also run a light torsion bar on the rear. That helps with body roll. http://img122.imageshack.us/my.php?...dsc000231ps.jpg

Brad's tuber is going to be pretty competitive in a few days. Redid his link mounts, got a SR and 645's.

We're going to have to allow rear steer in the 2.2 class in future comps. I run it, brad now does, and have 3 friends all building tlt's with rear steer.

UTRCRC is going to 4ws next season. However, they are talking about just Y-Harness steering NO CRAB steer...
My 2 hitec servos just came in ...just waiting for the Pede diff gear from Champain IL so I can get going on this.

They feel that it keeps the class more competitive with no indi. I agree. Makes it more of a drivers comp than a best equipment comp

Default Progress...



What do you think? I was inspired by the Spidertrax rig. 2-3/4" center clearance.

Woah, I was going to make the same exact same chassis. I have some more pics of the spyder chassis if you need any, but from the looks of the drawing, you got it pretty good.

Well, good luck with the project. I'll be looking forward to updates. You might even inspire me to get my drawings back out and build her.
