I set mine up today and had a good chance to see the truck apart.It has my spektrum receiver, castle mamba max pro and SCT 3800 motor (not the SCT mmax pro combo) and a HS-5685MG high torque and high voltage servo. No changes to the chassis. The battery is charging. Its a thunderpower 4300 65/130C hard case and it fits perfectly.
I had to remove the motor because it had one of the motor mount bolts put in on an angle which messed up the threads in the endbell. The motor was holding from one bolt and had a loose pinion with no loctite. The SCT motor was put in since I plan on sending the original motor back to HPI.
I think its a solid truck and like the general look and construction of it. I feel it is terribly overgeared. I am verifying the gearing and will put it in a calculator. I think the larger spur gear and the shorter end of the gearing chart is a must on 3s. From what I know of this motor and ESC combo in 2wd short course and stadium trucks, this truck will likely make it run hot. I will take temperatures when its driven. Its only about 40F here though.
Negatives are the motor plate setup having fixed holes and lack of camber adjustment and the optional spur gear (or any optional or standard parts) is available. Its a bit more work than normal to get at the motor and pinion but acceptable.
I'm going to look into turnbuckles for it and get at adjustments.
It looks great on 2s and its probably the right battery for it but I want to go 3s and access slightly higher speeds. I agree with red to set it up to 40-45 mph, have fun with it and let it run cool.
