Spool vs Diff vs One-Way

I am able to drive one way and spool. With spool, i can take corners using throttle instead of the steering and the feeling is great...Using one-way, u need to find the braking point, throttle off and then slowly increase the throttle as u enter the corner. However, both spool and one way require different settings.

I used to run 1-ways all the time in stock until I switched to a 13.5. With all the torque from a BL the 1-way was un-managable on pavement. On carpet 1-ways were a little better but I did not feel as aggressive than I did with a spool. Gotta love 4 wheel breaking.
The only place I run a double 1-way now is with a mabuchi/johnson motor setup.
As far as a front diff, I would not suggest it especially with a BL. I had to learn that the hard way, the front diff loostened up during a race, started slipping, then burned up, the rear diff then started acting like a rwd car started slipping and it was smoked too. Never had that happen before, but with the torque of the new motors, you are better off with a spool/diff setup.
I never tried the 1-way grease packing technique... sounds like something interesting to try....

I had never bothered with a spool because of the damage they tended to do to outdrives and universals. But after I got an Mi3, I found that a spool was great for rubber/carpet.
And now that I've switched cars, thats still what I plan on running. I think if your going to run a diff for rubber/carpet, then it should be run really tight, almost locked. That way, it will give you spool like feel with a little less wear and tear on the universals and diff outdrives.
But I think its something thats definitely NOT a absolute. Spools-oneway-diff has always been a matter of preference and feel. Heck, I would never run anything other than a one-way on asphalt with my nitro car, but have never been able to get it to work with electric sedan on the exact same track...

diff for running on foams (exept nitro sedan, one way takes skill but wicked fast)
one way for rubber on asphalt and stock class rubber on carpet.
spool for any rubber tire class above stock on carpet.

There is also the combination of center one-way with front diff!!

Is there spool for xray?

Yeah for me. One-Way was the way to go when using a 10 Turn motor. I switched over to brushless though, and now the braking issue is more pronounced where it doesn't have any front braking at all. So that's the main reason why I was trying to get things adjusted.
That's why I brought up the thread from the dead.
