Got some updates...

Not sure if this will work the way it is...I have another hub on order so I can add another set of gears.

So the motor will have a 9 or 10T pinion that will go to a 48T spur, on the same shaft opposite of it will have the 24T sprocket with chain going back to a 24T Sprocket which is on the axle.

Some mock up of just the sprockets going to the rear axle.

I like it
Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming to the Lord,
"Wow, What a ride!"

Thanks Jim! Yeah, I am going to abandon the whole chain drive deale'o and just go with two 94T Spurs and two 9 or 10T pinions and which will give me close to 100:1 ratio. As I add a tooth to the pinion I can slowly bring it down...I wanted to keep the chain drive but I need another way to add a jack shaft and I am out of mounts...

I also found out that they are having a test tune on the 20th so I need to get this thing ready. I hope my parts I order get here tomorrow. I am going to work on the body and mounting for the rear while I wait for the gears.

Thanks Andy!


I would say yeah. It is built to pull heavy amounts of weight and their are so many different types to choose from. :)

Yeah, but it's not really an off-road thing.....but.... it IS still basically a tractor...... kind of a grey area... you know..?

I'm okay with it if everyone else is.

Couple of observations... Are you building this to any specific class? Check out nr/ctpa website for a standard. I am a noob in this area and only borrowed a truck and ran it. But here is what I learned...

If you are looking at the 10lbs 2wd class... Try to get as close as you can to 10lbs using those suitcase weights. Most of the weight should be on the rear axles (or just in front or the rear tires) for bite. Some of the weight should be hanging off the front of the front tires.. The goal is to see the front end just barely bobbing up and down 3/4 of the way down the track and sled is at top of its run.

In addition, height of the rear hitch matters. Too low and you are dragging- too high and you are bobbing to early (hard to to steer and keep in line). Depends on a number of things but it should be easy to adjust at the track. The rule book on the nr/ctpa site has the hitch height limit. When I pulled I was close to the top of the height.

I will see if I took some picks of the truck I borrowed.

Looks good, you are inspiring me :)

Brad from TTR is a wizard at pulling, be sure to ask him mucho questions.

Thanks Mike!

This is going to be in the 7LB 2WD truck class. The hitch height max is 2 inches. I can drop it down by adding washers until I get the right height. I have weight for but until my gears come in I am at a stand still. I need to get the drive train done so I can move on to the rest. I do have the front steering done, and now the front body mount....

I am heading to a practice meet on the 20th so I am pretty excited to get this thing done... :wink:

These are the rules they use for the club I am going to be joining...

Chassis: May be scratch built or a combination of kit components. May be built with any of the following: Steel, aluminum, fiberglass, or plastic.

Tires: Rear tires are to be Tamiya "Wild Willies, Lunchbox, or Midnight Pumpkin" type tires only. Front tires are to be a minimum of 2 ¼" in diameter.

Weight: Maximum vehicle weight is 7 lbs.

Dimensions: Maximum length is 19 inches. Maximum width is 9 inches. The furthest point forward from the centerline of rear axle shall be no further than 15 inches.

Wheelbase: Maximum wheelbase of 11 ½ inches.Hitch:2 inch maximum hitch height.

Body: Must use a truck, van or car body only. All components must be under the body. Front tires must be in wheel opening

These were taken before I ran. I ended up swapping like four weights from front to rear and then buying a couple more and tossed in the rear. I believe I had to raise the height of hitch.

Hope this helps
