John, what type of problems are you guys having with the irs pins in the axles when running a oneway or locked diff?

Oneways and locked diffs put a huge amount of stress on the dogbones, pins and outdrives. You will get wear no matter what... The IRS pin cushions almost act as a sacrifical piece to accept wear. It is much cheaper to replace the pin cushions then replace the outdrive wear.

The IRS pin cushions tend to get cut in half by the locked diff outdrives. The pins tend to bend. I aggree that they act as a fuse to protect the other parts.

I have used the combination of IRS dogbones, pin cushions and front spool running modified on carpet with foams. This is probably the highest stress situation. The pin cushions will wear but are replacable. I am almost certain that metal pins would groove the outdrive real bad. Metal pins are not an option in my opinion.

Does anyone make a blade-style pin (similar to Schumacher) where it contacts the diff outdrive? Seems to me it would last longer... although the added friction caused by the extra surface area of the blade in the diff outdrive slot has been known to reduce suspension oscillation on-power in offroad vehicles. (less traction) Just a thought...

ya i would much rather replace the pin cushions for 5 bucks for 4 then replace the outdrives at 30.00 a pair.

davew-xray uses the blade style pin cushions but im not sure if they will fit the regular tc3 dogbones. ill check.

I am looking for some good setups for stock touring car with rubber tires on carpet. I have tried several different ones and have yet to go as fast as I did with my XXX-S. Any and all setup reccomendations are appreciated.

Thanks,
Tony

Dave,

Is this what you're looking for?

They're not cheap though.

Good luck.

Default IRS Front Spool, Locked Diff

I tried the IRS spool in the front of the TC3 on the indoor asphalt at ReflexRC. I tried it first with my setup for the one-way. I did not have enough corner entry steering traction (turn in). I changed the front spring from blue to silver, all else the same. Felt good. Setup is the same as I have listed on page one of this thread except with silver front springs. Turned the rear droop screws down 1/4 turn to remove some rear droop. Felt better. The only problem that remains is the rear got a little loose on the last couple of laps on my practice packs. Power was down at this point so I don't think this will be a problem in a race. If it happens in a race the cure is to move weight back a little. I think I will drill and countersink two new holes for the servo and transponder to move it back a little so that the ballstud on the servo horn will go forward rather than backward. Moving the 6 cell pack back is too much weight on the back. Over four ounces extra on the back. 2 -3 ounces more weight on the back with body off seemed to be about right on the Losi with a locked diff. I'm at 1 ounces more on the back right now.

Handling was good. I could actually run a tighter line on a couple of turns. Acceleration, which was already good, was just a little faster than with the one-way. This is the main benefit which comes mostly from the lightweight parts of the spool compared to a oneway.

What would be a negative on the Spool? You probably can't tell wear yet, but could that be an issue? What would make me want to buy that over a one way(I just have a regular diff right now)

Sorry to jump around in topics but going back to what Mike D said about setting tweak (or weight bias).

I also had the problem of a leaning chassis, I had the weight bias the same and the car handled very well (need to work on my driving more ), but i just dont like the idea of the chassis leaning.

Mike says to set the front left and the right rear the same preload (i.e. same spacers/turns on the shock) and then set the other shocks accordingly. Is this a correct interpretation, and do I need to compensate for the extra spacers in the rear shocks (i.e. droop)?

any extra clarification would be greatly appreciated.

thanks

Associated Racer- The negatives on the spool is that it eats front bones or if you use the IRS bones then the pins and pinpillows in the outdrive. The wear on the pin holes in the CVD cups are also accelerated. On the Losi I got about 1-2 seconds faster race times with the spool in stock from the lighter weight. For reliability reasons I had not tried the locked diff on the TC3 yet. Since the one-ways are hard to get right now, I thought I would develop a setup for the locked diff, before I had to use it because of parts breakage on my now unavailable oneway.

Nabman20-If your chassis is leaning then the ride height is not set correctly. Say the left side is low turn the collars down on the front and back of the left side the same amount to raise this side of the chassis. Use the height gauge to reset the height on this side. Once you have the height set then its off to the tweak station. I described how to set tweak earlier in this thread. Setting Tweak

droop adjustments will not affect the tweak or ride height, that is if you have some droop, which you should.

If I could get a one way, and I could get a spool also, what would you recommend I do? My driving style: I like a lot of steering, and never need to brake cause I race stock. Would one ways help with push?
