man that is sweet, especially with the long grunt at the end like the truck was actually straining. do you guys have fet stacks and mod motors? and where can I get one of those sleds?

nope, not fets stack and we are just running stock motors. the great thing about it is that the traction on the OL break on the track. I guess if you were adding weight to the OL then it might become an issue.

One of our members build the Sled. He is a member here "Clodguy" but for the most part is just a lurker. :(

I can see if he is interested in making another one.

Pretty cool B. I use to do that in the larger scale RC bout 20 years ago. Its got me thinkin! Have you tried tying off to the truck in other manners. Maybe going over the axle will give the possiblilty for front end rising up or more traction

wow looks really koo. I love how yall have the mass so that its varying position will change the force required to pull... very innovative. Did you make that contraption?

@ DougBoy - thats what a nelly is for... hehe

wow, this seems awesome! but i got a question, if the fets dont fry, wont the gears strip with this? i might do this with just weights but im afraid that ill tear up my already semi-torn up gears. got a nelly evo and plasmatomic ready :D

@ nivlacs3z that design is used in real tractor pulls, he didnt invent the design, just scaled it down for Mini use.

To the pullers: You are begging for fried fets. When I first got my OL I was climbing a small hill made from RCP tiles, the tires were spinning, so I figured everything was OK. Then it died. When I took it apart I was suprised to find that the fets had not fried, but instead had gotten so hot that they de-soldered themselves from the board and were laying in the bottom of the chassis in perfect condition. Luckily I was able to solder them back on from experiance with past fet stacks on 01s.

Well if we do fry the fets. I guess it's time to upgrade...lol

it's really up to the driver to know when he is done. same works on 1:1 scale if you push it to far something gonna blow.. :D :D

Beff up the truck and pull your heart out. Now that looks like fun.
As a club we wanted to do this. We were going to use Xmods with
4 wheel drive and stage 2 mortors. Great job on the sled does he
have the plans he can show us how to build one. TO:cool:

Heh... never knew that. I've actually never paid attentioned to tracker pulling. I'm telling yall, just grab a nelly evo or stacked and you'll be able to let your motor pull as many amps as you'd like.

Plain and simple -- that's a cool rig.
I would like to see a video of the MZM on dirt pulling the sled. ;)

I'll see what I can do. My MZM is quite beefed up with alloy, Fets and an Atomic Stock motor. I'll have to add some serious weight to the sled. I'll see if I can get some video once I borrow the sled and set it up.

ok, all this talk about OLs made me ask this question(s). are the GPM delrin main gears any good? also, how did you rig up a hitch to the OL? finally, what other upgrades might be needed to get trouble free pulls/tows?

I'm running the GPM derlin Gear in my OL, it works great.

It all depends on what the weight is you are trying to pull. the heavier the weight on the sled the more stress on the components. and you will probably have to add weight to the OL as well. Tire can make a differece and so can track surface.

I'll get a pic from the under side so you can see the mounting. Luke came up with a very simple yet effective solution.

send them an email or open up a service ticket and ask for it specifically.
