Manu,
Well, I like the 2413 because it's small and light.
At the moment I use the 2365 because it has little more kg, makes the car little smoother to drive and keeps the steering better over the 2413.
Oke Phil! Meet you at the ETS!
Green Speed,
When I come on the track I discharge my cells individual till 0.9V I charge them and after my run I leave them till next practise run. If you are not using them for longer then a week it's better to charge them a little bit ( 500mAh).
CraigM,
I suggest to try little harder shockoil in front or 100W thicker overall.
