My mm setup was badass but the rear configuration was easier for me to drive fast. If we had just a little more traction at my track... I woul have stayed mm. We have more than enough for rear motor however

Anybody remember how long it took kits to become available after the first prototype was spotted?

I run the narrow holders and I seem to get better rear traction than the wide ones. I believe you run at NorCal Hobbies (noticed the same handle as the youtube videos of the club races). I should be out there on Sunday if you want to check mine out.

I thought it was a month or two.

Keep in mind that just because you saw a prototype doesn't mean they will release the car. Associated ran prototype cars at the World's in the early 90's (if I remember correctly) but they didn't see production.

I assume a ZX6 since there was some photos of Tebo with a 4wd buggy with an aluminum chassis.

The RB6 is what I was thinking because we knew 100% sure that it existed after the race at Hot Rod Hobbies. A month or two after, I thought we were able to get our hands on them.

I am guessing the same logic wants to be applied to the new 4wd buggy Tebo raced a week ago. But I wouldn't count on it coming out before the world's because if they win the worlds with the new car just imagine the advertising campaign after the event.

Yeah think it will be around that time sept or so when the indoor season gears up mostly . Anyways glad the wheeler class is coming back full force. Cars also seems a lot tougher, we get 2 full heats on club nights and most of them complete the races.

I'm install the Triad slipper on my RB6.

It says to not use the supplied washer but to use a thin one, but I don't see a thin washer supplied.

Can anyone help please?

Looking for a little help. I'm using a savox sc 1251 servo and would like some reassurance that I used the correct servo spacer shim. For those that have used this combo which should I be using?

Thanks.....Greg.

To expand... you need to purchase the Avid top shaft for the RB6 in order to use the Triad slipper.
