again very helpful V-rossi. I already run 1 oz (29g) of lead behind the rear tower. I also run the X-6 wing though with a very low cut.
Have not tried the yellow spring though so will keep that in mind.
I do however run a 19g brass front bulkhead (GHEA one, not the heavier Trishbits one).
When you run the 200g lead under the lipos, what lipos do you run (weight) and what is the cars total weight set up like this? Mine comes in at 1650'ish race ready.
When it comes to throttle control and also gearing/rotor/esc I definitely see your point. I do however like to think I have at least an ok throttle finger

I would say I am not known for being the most aggressive driver out there
Regarding the front tires I always have felt like the car understeers quite a lot with the proline's, and so yes I have tried both the 25 and even the 20 degree blocks without really feeling any improvement...
Do you run all the rear toe-in using a 4 degree toe-in brace or do you add the rear toe-in using 1 degree hubs?
Again thanks for your very helpful replies V-Rossi.
