work with control 1 out of 10 times, sometimes push the controller's trigger into reverse 30 - 40 times and then it would finalllly drive in reverse sometimes at the slow speed I was trying for other times it would go full speed reverse. The servo mount and back of axle have mounting holes so a 4 link could mount up nut I do not have that kind of skill, Prefer a buy it/ bolt it up package. Reprogramming the esc/controller did not help fixing the reverse problem at all. Putting the controller into low speed made it worse and turned the servo from good to useless, sent mine back, Do not know if it was a oops from factory or if all are like that. A slightly more offset beadlock would of gave full steering, my losi trekker wheels fit, but, have less (closer to knuckle) offset, so ddt's wider rims for the new rc4wd tires would be perfect. If they address these issues I will purchase another but for now going fast with not much steering will pass on. Would like a motor setup comparable to axial scx10 series 1 with a 55t or even a 80t/100t motor options, using the stock pro-line's setup as if the axial came with the 20t motor in it with 87/19 combo.
