Is it possible to see a picture of this?

divide 34 by 20. gives you 1.7. Some guys have come up with an alternative. Using the stock front spool (38 tooth), and stock rear diff. with T2/007 center pullies (20 tooth) you can use the yokomo rear belt(pn L189) and the MI3 front belt and it works fine. track performance would be closer to the 007 rubber spec. and you wouldn't have to use crazy spur/ pinion combos. down side, you will notice a lot less off power steering especially with brushless. I tested it last week. I was able to get the gear ratios i needed with xray spur gears.. RW gears bolt on. kimbro works if you flip the center layshaft around with longer screws(full thread engagement) if you sand the spacer.. PRS, works with slight mod. I used one of the tc gears they don't make anymore. But the new batch may bolt in. Herass shumi and we might be able to get the RW spur gears that are rumored to be specificly for the 008. *I talked to them last week about it and they said they were working on it*

Cheers,

Patrick

Dag,

I didnt drill a hole or anything. I use a 88/50 for 13.5 at BCR raceway. I use a 2mm ball driver and tighten the motor from the bottom in the rear battery slot. I angle my driver in between the spur and pinion and I can tighten the motor down. It sounds funny but is no problem to do it.

Teemu Leino tested the pully's back to back and uses 34/20 because he thinkes the whole driven-train just works better with these pully's.

He TQ'ed DHI cup with 34/20.

The drive train is more efficient with the old setup, however there are handling benefits to the new setup. There is less belt wrap on the 16 tooth pullies, so belt tension required is increased. Belt wear is accelerated as well. However, with the spool and the tracks I run, vs my driving style. I do like the short internal ratio more. I am used to running a one way or a diff (ran only the end of last season with a spool) so the extra off power steering from the new belt/ pulley setup is nice. Fair enough? he also lost to a car that had a 2.05 internal ratio 37/18. To me, its all prefrence.. just like with anything else.. if you like it.. run it. Because thats what everyone else will do..Teemu is also finish, and crazy lol. and if you test the 38/20 drive train, you would say that works even better than the 34/20.... because its more free than the 34/20.. end result, its all what YOU need to go fast that matters.. I love the 38/16. And my alternate is 38/20... I likely will only run 34/20 on the foam car

I tested all the different pully's and like the 38/16, but it wears so much.. like 4 batteries and you need to replace the belts. Also I tested 34/20, and think you have less traction roll with them, but more steering. I liked it. At this moment I drive 38/20 because it feels more like 38/16, is verry smooth verry free also, and te belts dont wear.

Did he lose because he was to slow? No. He made a mistake, thats it. Vicktor was really fast thats true.

I know he didn't lose because he was slow. I was just busting balls, because mine were being busted lol. How do you come across less traction roll? It sounds like its more a problem with huckl-buck

What? You mean that with mod BL motors, right? For those using 10.5 or 13.5 motors, wear should be very little and just as good as with the 1.7 IR, right?

For mod racing, maybe? But what about 10.5 and 13.5 BL?
