Just wondering where I should start with upgrades. Been having a blast driving it as is but I already sent a few issues. It's not as stiff as I want it to be as far as twisting of the frame goes . Same for the steering link . They are already bending considerably. The frame is twisting right when I hit the throttle as well. I freaking love it though. Also any tips on how to lower its center of gravity would be of help. Anything with a pitch around 65 or greater and I'm tipping end over end.
