I had no experience with gear diffs before owning this car but all the testing I have.done has.told me the.opposite is.true. The two gear diff has very constant performance giving you he same.amount of limited slip effect regardless of how much diff action is going on. When you run the 4 bevels you get an increased limited slip effect in realation to how.much diff action is going. To me the 4 bevels is more like a ball diff in how.it drives. You can also get away with a lighter diff when using 4 bevels bit still get drive off corners.
In the end it depends on what you need as to what is better but most people who have one.locally has put in the extra bevels when I suggest it to the and find it a better car to drive.

every track is different, grip levels , driver preference. it isnt right or wrong to use either 2 or 4 gear. it is purley an option as to which way you go, there fore i dont feel its required to have this option in the kit.
in gas when diffs got smaller, we used thicker oils to get the same feel, less fluid capacity mean we had to go thicker oils. so will that transfer to 2 and 4 gears ? if it doesnt rain tommorow, i am testing this out, 2 and 4 geared diff with the same oil, same conditions same tyres. we have had limited running here due to this bad weather every 2nd Sunday ! today was a nice day , lots of sun, we need to change our sundays , hahaha

Last night I finally got the chance to run my Serpent, and was very impressed on how easy it was to drive.
At the track there were 3 people with the new S411 and we all experienced the same problem.. The Universal Drive pins would back out. Now I know that we can dremmel them to flat spot the pins, but I was wondering if anyone knows if the x-ray ones fit? If so is it this part?

My point was aimed elsewhere. But you are correct. 4 gears feels like a ball diff. the point being a 2 gear diff is not a draw back from purchasing this kit.
every track is different, grip levels , driver preference. it isnt right or wrong to use either 2 or 4 gear. it is purley an option as to which way you go, there fore i dont feel its required to have this option in the kit.

IMO, I really don't think that a 4gear diff is really needed. The 2 geared diff is plenty strong enough, and can take a multitude of Mod punishment without breaking a sweat. As Patto said, the 4 gear diff is a tuning tool (read as in optional), and it is rare in this day and age for any manufacturer to include 'options' in the kit. One of the other reasons for leaving it out of the kit was to bring the price of the kit down to a very competitive level, without sacrificing performance.
What is the cost of two more bevels and a shaft to the manufacterer? $2 - $3? But if I want the extra bevels I can't just buy two bevels and a shaft, I have to buy a whole revision kit for another $30. So why don't they just add the two bevels and shaft in the kit and charge $455USD street price. In the end I would save $25 and the hassel of having to buy an extra part. Plus that savings can go towards other more needed spares.Frankly, I don't see the two added gears as a "Tuning" option. I just see it as a cheap way to skimp on the kit. Suspension arm brackets, sway bars, and springs, most definitely yes those are "Tuning" options. A complete diff, ball diff, or oneway, those are tuning options as well but two lousy bevel gears? C'mon.

I think that is up to you and your level of comfort. If you feel your servo is strong enough to withstand forces of impact or the lack of chance for impact in your style of driving then run without the servo saver. However, if you want to be on the safe side, run the servo saver
I am using the Xray T3 servo saver. I had to add a 1mm shim under each servomount.

i pretty much just finished the s411 build and the car is beautiful! maybe it's just me but the narrow chassis makes the car look so small. i would like to share some of my build experiences with fellow s411 builders,
step A19: i used an associated tc6 106t 64p spur #31334. the spur fit with no problems or modifications.
step A24: i used associated king pin shims #8425 on the steering bellcrank arms in place of the stock shims. i think they are 0.010" thicker than stock. when i tried the stock shims the bellcrank would not work properly because the countersunk screw would hit the bellcrank arms when the steering assembly would go through it's motion. with these thicker shims the steering assembly works without any interference.
overall the car went together very easy and again looks beautiful. anyone thinking about getting one should not hesitate, it's awesome!
