RB/Chad - I found that I had to back out the eyelet a little if I used
the 0 deg front kickup. The prob may be worse with LRC and
0 deg kickup?

Evil_S10-I my opinion you should run the std .36 shocks in the rear(both shafts and bodies), and run the short .28 in the front. For the fronts the cheapest way to get this is to buy the A-5081 .28 set.

I attempted to install both the short .28 shafts, and short .28 shock bodies in the front after converting to the LRC, but could not get anything lower than about 6-8 for droop. ( i forget which, but it was pretty rediculous. )

I fixed the problem by going back to the .36 bodies, with the .28 shafts.

That is strange, like I said I have no issues with the .28 shocks and 4 or 5 other people I know do not have problems.

Yeah, the shocks were definately bottoming out. I removed the droop screws, and i was about to whittle away more of the bumper, and then i noticed that nothing was really touching, i removed the shocks... and whammo... the arms droped like bricks.

I put the .36 bodies back on, and had no problems.

What are those 4-5 other people running for droop? ...hehe..

You guys must be running rubber tires-

With 2.25" foams and .28 bodies, to get down to 3 or less on the droop guage, you a have to unthread the ends a about .100" over half the threads. I run .36 bodies with .28 shafts. When I run rubber tires i just cut half the shock end off to get uptravel....just like we all did when the car first came out and there were no .28 shocks.

Even with rubber tire's I can get the droop where I want it with the LRC blocks on. I have the short shock bodies and shafts on my car.

Unhappy Roll Center

I still have problems understanding roll center, is there any literature that I can read regarding this topic?

Most people at my track run Tamiya 414M2, and all of them are using HRC.

I myself converted to LRC after reading the posts in RCtech

???

hey guys, i just got a XXXS. Pretty hopped up with graphite conversion and and all MF hopups.

Right now i have a Yellow Spur Gear in the car i also have the red one and orange one. Does anyone know if this is Stock Spur? Its a Bright Yellow kinda looks greenish but when i look in the magazines the Stock spur is Bright green limish.

Does anyone know a good gearing to run for this Yellow Spur? I believe its 48pitch. Im mainly looking for Top end and top acceleration.

thanks

the yellow one is stock. I would go out and get a 128 blue spur gear 64p, why you ask I think its why better for helping you out in the gearing department. I would start out with 128/39 gear down form there do not go up more then one tooth

GotRice?
The Spur gear you have (the flourescent yellow one) is the stock spur which you were correct in stating it's 48 pitch and it's 88 tooth. The Orange spur is the 90 tooth, and the red one is the 86 tooth. With a stock motor and the 88 tooth spur you can start out with a 26 pinion and go up if you need more top speed or down one if you need more acceleration.

I have never had problems with ride height and low roll center, neither has anyone else I know so I can't offer any help on this matter. I use the short bodies and short shafts up front with no problems.

Pembalap: Low rollcenter allows the car to rotate the middle of the turn much harder allowing you to hold your line through turns much tighter, thus increasing corner speed.
