I put some 1/8 OFNA 20mm truggy springs and its plenty stiffer now and it is a little better.
My only issue is the mid-air control. Its got none to pull the front end up if need be.
And on 4S, its not because of lack of power.... She needs to practice with it more but I wish it was just easier to drive.
I bought it for her because I thought it would be very stable and easy to drive over the jumps and stuff. Boy was I wrong. I got her the one thats the biggest hand-full
And yes it can be driven hard with little regard for others. With my little 3lb 1/10th scale buggy, I literally dive out of the way when she comes around the corners
