60 48p is the same as 80 64p. The way my car balances L/R, I might want even bigger than 80 for 17.5. Plus ive always found bigger spurs to be faster. More leverage for the motor to turn the transmission. More acceleration, better motor temps

that is an interesting observation. nearly every time i run 17.5 TC i end up close to a 3.4 FDR... so i just like to make sure i can get to that gearing whenever possible.

I was geared 4.06 at nats, and had the fastest car in a straight line as far as I could tell... 80 spur fits up to a 3.33 according to the book

I would try to unscrew all your topdeck screws including the pivot balls.
After that, press the chassis on a flat board an screw the topdeck.
I'm not sure if that was your question but i think

MMMMmmmm......I'm about 60% done with the build on my new A700EXL and all I can say is wow!!!! This thing is so nice I now see why it has the price tag is does....well worth the money spent I do have an issue/question, when I build up the gear diff it seems notchy and tight like I'm running thick lube but I'm only running 1000wgt. Are there any tricks you guys are using to get the diff smooth? Is there something I need to look out for when building the diff? Thanks in advance...

I don't have one of these cars but my dad does and I would say since the gears are spec r I would flat sand the backs of them till they are perfectly flat this way no burrs can catch on the geardiff pin holders.

Teach, do what jeff said. Also, rotate the gears as you tighten the diff gears up, seems to help make sure everything is seated properly.

I would do the gear diff modification. By doing this, the gears become smoother and won't wear out too fast

I can't post links yet for any reasons, but you can find it on petitrc or on the awesomatix web site
Hope this helps

my car kit is coming along. Plan to have it done by Tuesday evening. I think I finally made a system for myself so the next build will happen quicker.

Hi all,

I'd like to know where to use ST24? Above and below AM06(S) or just above?

Regards,
G-rem

Make sure NOT to sand TOO MUCH OFF..the gear diff will slip ..
