I guess HPI realizes the benefits of shaft drive.....

tphalen,

earlier you mentioned that you would have to do some tuning to make your car handle better with one-way. I'm running a tight track and thinking of putting the one-way in. In general (I know it can't be exact), what changes do you make to the car to better set-up for the front one-way?

How's it going TP. Not to second guess you, and I;m not as experience in these cars as you, but I actually made that change from the bushings to the bearings. I only run my FTTC3 in Stock class so that maybe why I haven't experienced any tightening in the diffs, but it seems to be working good for me. Because i took the seals out of the bearings on the outdrives I always checking and maintaining them on a regular basis so I check the Diff action while I'm in there. I haven't had to make too much adjustments to the diff since I made the change. I do notice that the bearings seem to give the diff a little more slipperage (is that a word?) but it also allows you to tighten it a little more and not do any damage to it.

Just my thoughts on this and my experiece with the ball bearings in the plastic diff.

Thanks

Just got a FTTC3.


Does the kit come with bearing for the steering rack? If so I did not get them.


Why is there one bushing used in the diffs? Could I replace it with a bearing?

yodance - the kit came with bearings for the steering rack, make sure that you didn't use them for something else, just a thought.

Bearings in the diff - that's up for debate but I use them in mine and I don't have any issues with them, I only run Stock so the bushings may have an adverse effect in MOD.

When the car is travelling straight the bushing in the diff doesnt spin or the shaft inside the bushing doesnt spin either so it doesnt hurt performance. The only time its used is when your in a turn, and because the difference between your inner and outer wheel is so small a bearing really doesnt do anything for the performance.

Im really not sure why people get their panties all in a bunch when they see a bushing here, its one of those places that it doesn't matter. It is a very common reaction though.

Why do they use bushings in the Factory Team kit? Why not bearings?

My guess is because bearings come in standard sizes you can specify their inner and outer diameter but the width is usually a function of the inner and outer diameter. Since the plastic diffs were a retrofit and the gearboxes were originally designed for the steel diffs so they couldnt be changed. The plastic diffs probably required more "meat" in the center area than the steel ones did so they had to add it arround the bearing. There was probably a bushing available in this width but no bearing (gotta make room for the balls inside). And like I said above in the diff it really doesnt matter.

That one doesnt need any break in you might put a little diff lube on the inside of it but thats really not needed either.

patelladragger: You might want to put a little lighter oil in the rear, or a little heavier in the front. One-ways tend to make the car steer! And I mean STEER!!!! You'll need to play with the setup to mellow out the car a little. My site has quite a few setups for one-ways....give it a look.

Dragonslayer: I actually have a setup on my site that I used at Kinetix. In just one day of thrashing I was able to get the car REALLY good...turning lap times right with the top guys there. They were FAST, so I was happy to get the car working good. Give it a try....it works GREAT on carpet!!!

Mike F: I'm sure it won't create any problems but, like patcollins said, it's not a big deal either way.
