Dumb question - how are you guys achieving such a low FDR ? I'm running 21.5 boosted class, and the biggest pinion I can physically fit with the 80 tooth spur is a 30 tooth (5.33 FDR).

What brands of spur gear are you guys using ? I assumed the AE TC6-style spurs were the only type of spurs that fit, because of the hole in the spur needed to access the motor mount screw.

What am I missing ? Will "regular" Robinson / Kimbrough-style spur gears fit, and still allow access to the motor mount screws ?

Use 64 pitch spur and pinion and use the 3rd motor mount screw hole.

I am currently using RW spurs and pinions in my 6.1,
for 21.5 non boosted a 66-68 spur and 40-42 pinion depending on track,

okay thanks, its actually coming with a rear gear diff and front spool. It'll be probably 2 weeks till I get there with my car, maybe 3 because ill be waiting on stuff, but i might make it saturday to test my dads that he just got if i get out of clinicals early enough

Thanks

I managed to round the head of the 2.5x8mm button head screw and had to remove it but cutting a flat head groove with my Dremel.

Is there any reason why the spur gear button head screws (ASC31521) are out of stock everywhere ? Tower Hobbies shows it as discontinued

You can use thundertiger part# PD9007 this is the same screw or PD9006 this is the same size but is a cap head style with a 2mm hex drive (i prefer this one)

Thanks. I've managed to source some Top Racing screws, which are identical to the OEM Associated screws -

I just picked up a TC6. The guy I bought it from had it mostly built. I am going through setting it up now. The problem I am running into is that I cant get the turnbuckles short enough on the rear. This is my first Associated ever, and it has been 10 years since I messed with a touring car for that matter.

Anyways, I took of the turnbuckle to see if the wrong ones were put on the back but comparing them to the other ones on the car. After I adjusted them as far in as I could, they are definately shorter than the other ones on the car. I am guessing that the way the sit, they are at about 3-5 degrees of Positive Camber. Turnbuckle is mounted in hole #1, so I dont have that adjustment to play with. Any suggestions? Thanks in advance.

According to the manual the rear turnbuckles go in #7 which is on the bulkhead. Thats the factory setting anyway and I think you need shorter trunbuckles to use the other holes 1-6. If you dont have a manual you can download one from AE's site. It shows the length of each link and you can compare what you have to that. hope that helps, I'm kinda new at the TC6 myself.

Is it possible that the previous owner, or you, accidentally mixed up the turnbuckles and put the front ones in the rear and the rear ones in the front? I have seen this happen before and it causes this type of problem.

This is correct. The turnbuckles provided in the TC6 kit are designed to be used
with the #7 setting.

So then I guess I need shorter turnbuckles, or atleast rod ends to run the other holes. When I look at the set up sheets from the other drivers, they use the other holes. I guess that is why I was trying to get to hole # 1

It is possible, but I compared them, and the ones on front were longer compared to the ones I took off the rear...which would give me more. I was too tired to think anymore on it, and now I am at work and the car isnt here for me to look at. I will work some more on it tonight. Looks like I may need hole # 7 in the meantime.



Thanks Rick. Please excuse my ignorance. Been too long, and so much has changed. So am I looking for shorter turnbuckles or rod ends when I head to the hobby shop? Thanks fellas

Stick with the standard rod ends but use a shorter turnbuckle. In some cases you will run the #7 hole in the front. Generally the other holes are used in the rear.
