i agree with what you say absolutly trigger finger plays a big part this one of the reasons why i love to race my F1 car it teaches you throttle control

I think you are missjng out then. The standard gear diff with only 2 bevels has a strange feel to it completely differejt to a ball diff and very hard to drive. Once you go to 4 bevels its starts to behave more like a ball diff so you can run much lighter oil for better rotation bu still have drive to both rear wells under power. If they released an option gear diff with 6 bevels I would buy it in a heartbeat.

I vary it a bit depending on track conditions... Basiccaly anything between 500cst-2000cst. Heavier oil will reduce rotation but offers more rear end stability so you get less over steer on/off power. When you have the car working well just drop the oil weight for more rotation speed.

I did some more testing today and have a fairly balanced setup. Its slightly oversteery on/off power at full lock (full lock being 100% physical lock) so you have "extra" performance when you need it but is generally smooth and hooked up. I'll post it up later when I get home. One significant change today was using a 3.5 rear toe (only just got it) which squared the rear end up quite a lot.

Well, I have tried the 4 bevels on a TOP Photon and personally didn't like it as much. What you say holds true but I'ts kind of hard to imagine why the OEM would want to include 2 gears instead of 4 if they knew it would be better. Does the Tamiya 415 comes with four bevel gears?

Hi hi,

My first post on Serpent forum, nice to meet you all.

Got my car for 3 meeting races, love the car so much.

Just some comments and experiences on gear diff:

I found my car is stable enough with 2 bevels + Xray 2000cst + 4 shims. Car has been ran more than 60packs and still going strong, for people who is still struggling with the rear grip on exit, I strongly recommend to start with the 411- basis - outdoor - D setup.

4 bevel gears would give better consistent feeling on the diff as I have found on my old 3racing Sakura, but with our metal gears diff it is a bit heavy compare to other brands. Hope some aftermarket brands will make some composite plastic gears in the future.

I also found running spool will give un-settle feeling during full lock turns (hairpin exit or slow/tight turns), especially on low to mid grip tracks, in most cases this could be fix by running front diff + heavy oil instead of spool, this will smooth out the exit but lose some corner speed on fast sweeper. One of my friend also run the serpent with the same setup as mine, but he is using front diff with kyosho 500000cst and I am still using Spool. test drove his car and feel easier to drive especially more trust on hairpin corners, but found spool still to be faster on my track.

Now my question:

Has anyone tested with standard 2 pieces motor mount and no middle screw on the top deck? Does the spur gear really strip? How does the handling feel after unscrew it?

hi most of the other cars have 4 beval geras the new x-ray diffs have 4 and all the spc r also have 4 aswell but they re all plastic with plastic lasy shafts and beval gears.
serpent is the only one i know of to make the metal gear i guess going from 2-4 beval gears really is just a tuning option
