Ran 4 packs through this yesterday, 3 3s and one 4s. Running on freshly cut grass, with some small jumps. The truck does feel light, and I appreciate the well designed rear dirt guards. Runs fairly quiet, too. Steering felt lazy, especially under acceleration. I may have had a thermal cut, since the 3s lipo showed 30%. Didn't have my temp gun, but both the motor and ESC got pretty hot to the touch. Started letting her cool down, between runs. As I assumed, if I were going to keep this one for a while, I'd up grade all the electronics. It needs a servo, and maybe a servo saver upgrade, just to get it turning at speed. I did add 4mm preload spacers, at all 4 corners, just to level out the lower arms. Maybe if I pulled those off the front, the car wouldn't push as much. The shocks felt good-properly sprung for general use, and good damping. I gave the truck a pretty good thumping, landing short on a mild step up, blasting over some rough, and the car stayed well settled. As far as I can tell, all the fluids are still where they're supposed to be. The wing took some fair abuse, but has nearly straightened out. No issues with the body taking damage, or coming off, after multiple cartwheels and bad landings.
I think the chassis has good potential, but on post run inspection, I noticed that the center support drive shaft bearing is very close to the end of the motor can. Not only that, but the stock 3668 motor only has ~3mm static clearance, from the drive shaft. The two HW XR8 G3 combos I have on hand both have 4268 cans (one 1900kv, the other 2200kv). Has anyone tried to shoe horn a larger 42mm can in this new 4s? Layout is revised, correct? I thought I had seen most reviews on this new 4s, but I don't remember any mention of motor upgrade space issues. I figure a larger pinion may push it out, away from the shaft a bit, but I'd be surprised if there was no contact between the shaft and that 6mm larger diameter can. These HW set ups are pretty powerful, and could be a handful, for the chassis. The areas between the motor, drive shaft, and center spine of the chassis, also have pockets that sucked in lots of grass/debris, that was hard to blow out. The truck is speced to weigh 9.26lbs, but is 10.5lbs on my 60lb digital hook scale.
