Your kidding? Either your motivated or you don't have enough cars
I have 3 Serpents to keep up with. I change my diffs every 2 to 3 months and they work fine. Its a whole day project for me to change the diffs on one car.
Not much time for racing if your spending days changing diff oils every race day.

>>>>>>Although, I run on a large outdoor track, which is fast and has big jumps and is rather demanding on any car.

me also....
But here Is what I"m seeing needs changing from the big fast tracks. Freaking alum a arms bending......I"m going back to CF. And now I see my a arms are tweaking. I'm assuming from my first month on this car from some high speed hard wrecks.... thats all calmed down now and I don't crash hard anymore so hopefully no more a arm changes for awhile. The good news is Serpent A arms don't break, they bend a little, ....keeping you in the race

>>>>>>>>>or I can notice that the car either wants to push or over steer slightly more on areas of the track that the car didnt before with fresh diffs.

I think this has more to do with set up/ tires and the temps, and track changing then diff fluids. IMP.

Currently, I'm rebuilding the whole car this week to do diffs, shocks, clean the Tekin motor, adjust the overall setup of the car, and maybe cleanup some wiring... all in time for the next round of the Norcal series...

I'm also thinking about getting this charger:

and this power supply:

I have the AC/DC version of this charger. Really nice. not sure I would want to carry around an extra power supply so I went for the AC version.

The only thing I don't like is it only balances my batteries to 97% yet my Onyx balances to 99%. Still I use it mostly because its one charger to carry that charges a lot more batteries at once. BTW, it does not come with 4 XH balancer adaptors, you need to by 3 separate for about $10e each.
