Yeah, you adjust tension by shimming under the 4 screws holding down the front transfer shaft. Not very effective though because by the time you get the long belt right, the front is too tight. I'd rather see a simple spring-loaded idler riding on a bearing.

I was going to make one for it... I do need new belts, and the 2.5 and 3.3 use different pulleys and different belts too. I think my other belt is the wrong one (so is my luck). My front belt is just right with no shims, so I guess that I need a new center belt...

I may give the one I have a try...

at least when you hit a car tire at 50mph you won't lose much! HA!

even at that, this is a perfect example of a street BASHER> cant get any more ghetto fabbed thant his thing.

looks like a ton of fun man.

I stuck a stop sign post at about 50mph yesterday, backwards... The body looks a bit rough, but it is still in one piece!!! My rear body mount/shock tower is a bit creased, but still works like new, luckily it is an rpm part.

I hit a big full trash can yesterday and it almost fell over. I hit is so hard the center belt came off... I will say that this is the strongest TC I have ever bashed...

thats def saying something, i usually find the less race oriented the TC the stronger, bash away man.

where is the backflip?

The only difference between the 2.5 and 3.3 belts is the front and rear belts. The center is the same since it uses the same pulley size. The f/r small pulley went from 15T to 20T IIRC, so a larger belt is necessary.

You might want to just brace the chassis. I know that the belt had a ton of play on mine until I braced the chassis. If you push down on the center belt, you can actually see the chassis flexing.

This is true, I am thinking about the front and rear belts. I will rig some sort of brace up, I have a few ideas in my head, but will wait for the neu cells to come in before I do anything.

On another note, I destroyed the front belt just now... I guess I get to order a new one, or maybe check the LHS (waste of time usually). The stupid hole in the chassis at the front allowed a rock in and it jammed between the diff and the front upright/shock mount. I may add a hole in the front to allow debris out... Bad design not having a sealed front and rear belt setup... Maybe I can make something. I was thinking about a new chassis for the beast...

Oooh, that sucks. Changing the front belt is a royal PITA.

Yeah, I had the diff out last night, swapped it for a locked one that came with the car. I had to take out about a dozen screws, not as bad as a jato diff though (is anything that bad?)...

Its actually easy to change a jato diff.. You know you only have to take the back out right? Just take the back out where the battery box is its the 2 first screws on the bottom and then the 4 on the back.:lol:

Yeah, I guess I meant the tranny when the idler and blows up. Still a pain compared to an electric rustler tranny.

Thanks Ryan, I can appreciate that remark as I am quite gangster myself.

I figured you'd say something like that if I mentioned 'baller'. :lol:
