oneway single lap time is faster but overall solid front is more consistant for me.
on the rear toe, this is what I end up. I think is because one of the left turn have really low traction so I add more to the right side.
U should able to control the throttle without doing this

Default Diff Oil

What brand of diff oil do most of you use?

Hudy Makes 10K, 20K, 30K and 60K.
Mugen Makes 10K, 30K, 50K and 100K.

Thanks

John

4. The serpent diff is sealed by three O-rings. 2 on the outdrives and one between the two halves. It should be almost leak free. A tip is to use a little bit of very thick sticky grease on the o-rings at the outdrives (lightly coat the o-ring and then install).

5. The gears last a long time. I'm still using te first set since the EC in Halifax (august). Also the outdrives seem to wear less than the ball diff. I check the diff when I do a teardown of the car and then I will make sure the amount of oil is still sufficient.
Julius, what is the proper amount of oil to use in the diff? Is there a certain way to fill it? I just poured some oil in, (twice) let it settle and screwed it together. A small amout came out of the last screw hole when I put it together.

Some rummers about 'a' new 1:10 car for the euro's.... but i don't think that will come out for the public in a long time... it will probably will be next season when the public receives a new car...

If your source is reliable then we all wait in excited anticipation!

I fill the diff with oil up to the point the small gears are completely covered. Then I rotate the outdrive so the gears all turn and the oil works to all areas of the diff. Then I add oil till again the small gears are covered. Repeat until the small gears remain covered after turning (you'll have to push the axles down after rotating as the gears come up in the oil).

Getting a bit of oil out of the screw holes is fine.

Is there any danger of over filling the diff? Does the oil expand when heated?

Is there a rule on how often the oil needs changing?

Thanks.

That is great bro...
OK just send it to me. If I like it I buy it.
Anyway, are you planning on having 10 bevel diffs set each for 10K thru 100K ?

Speaking of the diff oil viscosity, one of my friends who drives an outlaw mugen with lola body shell goes with 100K oil. He said, my car behaved just like a 1/8. lol.....

That`s extreme... I think 60KW would be very nice in the situation of last JITC Futaba Cup where new suface emullsion coating applied. I`m sure you will like it.

Anyone of you use the Mugen super grease for the gear diff? I think a lot of mugen racers have use it with great result, don't know if it work with Serpent.

so far , we tested 20K & 30K work great (using Kyosho oil)
another guy tried 50K but his car looks very strange so I guess too hard.
ACO surface just been "re-coated" so traction is fairly good.

Default Front Droop

I am having a difficult time getting my front suspension set without binding. My problem seems to be with the sway bar cam and mounting screw. When I tighten the screw the suspension binds. When I loosen the screw it is free. I am using the orange aluminum sway bar mounts and everything fits fine. They rotate perfectly on the hinge pins. Also when I rotate the cam to 12 o'clock it binds the suspension even with the screw loose. When I turn the cam to 1 o'clock (and beyond) it's free.

What am I doing wrong?

Thanks,
jag
