Just took my slash 2w out for the first time. WOW what a blast, but have some Q's. It doesnt seem much to fully compress my shocks, small jumps, hard turns, even braking, they are all factory set still. Is this the norm for factory specs? Or do i need a heavier oil, different placement? Also if i change my radio from 50/50 to 70/30 do I really need to reprogram the ESC? If so do i just do it like i was syching a new radio? Thank you for any help provided

-Noob on course
