The thing I find interesting about gear diffs, is people talk about the being "very tuneable for different surfaces" by changing the oil.
Now, to do that you have to drain the oil and put new stuff in, which MAY be a 5 minute job, IF you don't make a mess.
With a ball diff, I jsut pop one ball joint, stick a driver in one outdrive and an allen in the other and tweak. No more than 30 seconds, and I can do it with everything hooked up and the car on the ground.
So, WHY does this "tuneability" thing always come out with gear diffs? What am I missing?

I have a short question, I remember back a bit a guy posted how to put quick change hubs on the front of the T4. If somebody knows, could you refresh my memory? I know a guy who was wanting to do it... Of course after he saw the qc's on my RT5

That makes them tunable and they do work well in 1/8th because that class of vehicle allows for things to be built more heavily than 1/10th racing currently demands. There's still inherent binding under load, all of the gears in a gear diff naturally want to spread apart when power is applied, that doesn't happen in ball diffs. Perhaps someone will come up with a way to make silicone oils more slippery (they're not great lubricants) with some kind of additives..
Also if you want you can add some grease to your silicone oil, works very good for diffs.

Spend the gears with out the top half of the gear cover .
They will push out of the pin slots rather easy correct ?
This the force Dave is refering to .....
When you put the cover back on and apply real power, this force is ampified quite a bit and as a result the gears & pins can bind against each other....
more power or torque ?
worst the problem gets .....
This why Nitro can get away with , gas motors have low torque compared to electric.....

Question: I got a composite chassis from a friend to replace the graphite one I have. He used shoe-goo to glue down his radio gear and it's still in the chassis, I like servo taping. Anyone know how to remove shoe-goo without damaging the chassis?
