Looking at replaceing my tc3 with a new car. One of the pita parts of the TC3 is changing the spur.

How hard is it to change the spur on the Yok? How many screws to remove?

Thanks

Thank you for the responses Matt and Lee, I have decided to go ahead and get the SD, in Black version. I just saw Chris Tosolini run his SD @ SoCal and I was impressed in how well it seemed to go through the turns, it had no tire "screeching" at all. Can't wait to try it out. Now, where's my credit card.....

Hi,

It's quite easy once you get it (not that easy the fisrt time, but after a few trials, it's ok). Remove the rear diff (2 screws, 4 if you're using anti roll bars), remove central shaft drive cup (only 1 pin to remove) and center shaft, unscrew the spur gear holder, you can get the rear axle out and you got your spur gear holder free (unscrew the top deck if you're using a big spur).

have a look at my article here . I know it's in french, but the pictures are easy to understand and you still have babelfish to translate...

RCBuddha : I've found the SD very responsive to the positioning of the suspension arms (you can either move them forward or backward, 4 mm overall) and this alllows to change the mass balance. This summer, I had issues with my rear tires overheating and screeching after 2 laps, giving a car very fast for thse laps and mainly undriveable after.

Moving the rear arms 1 mm backwards (thus having less weight on the tires) allowed me to keep the tires at a lower temp. After that, my car was perfectly consistent during the whole heat (without heat ahahah), no screeching from the tires at all and amazingly fast.

Changing the spur is not super easy, like it is on an Xray, for example. There may be fewer screws, but changing spurs still takes some time. It's a little easier to do than on your TC3. Don't pick a car for it's spur changing abilities, though If you get the SD you'll find it has a freer drivetrain and better quality composite parts The chassis is much more flexible though

I've gotten most of the other info so far on the yok. Spur changes seem the be the most PITA ob that I do at races, ust want a comparison to the TC3.

Can the chassis be made stiffer?

The only good permanant track in Alberta is up in Edmonton. It is only in use during the summer and is large enough to run 1/8 scale gas. Their website is www.edmontonrc.com

sands: Yes, you can stiffen the chassis. I run it with 2 top decks, which helps, but it's still is not as stiff as the TC3. The graphite transmission cases coming should help stiffen the chassis too. Then, of course, Yok is coming out with the tub version which will hopefully be as good as the TC3's tub (but without the heat-tweaking!!)

I have a feeling that a little bit of that was because of Chris

Randman- I've never broken a front drive cup but I've gone through a couple rear ones. After I replaced the rear with aluminum I haven't broken anything in the drivetrain. It wouldn't hurt to put one in the front but I have two SD's so I only got one set for both my cars

Well for now, I only have the 1 SD I got the RS ultimate conversion, aluminum rear dogbones, titanium front dogbones, titanium axles, titanium input shafts, titanium screws, titanium kingpins, and I know I'm forgetting some other stuff, but dont worry, it'll be bulletproof when I'm done
