Thats great! I never used the US warehouses because of UPS lol, but knowing purolator is there now is awesome
Heres a pic of where those white things go

the ones that have an indent are for the suspension hinge pins to hold them in place, you can see them clearly on the rear end of the car in this pic, the ones that look like clips are indicated on the front of the car, they go between the A-arm and the shock tower to reduce slack, you clip them right onto the hinge pin holding the A-arm.
Ahh thats a nice article! I never go to the track so it never dawned on me but I might have to change my setup a little in the summer
Check the wheel nut or the other adjustments for that right front wheel, might be something loose.
Programming it manually isnt too bad, I only changed the LVC to 3.4V per cell, but it was easy to do, although you're right a programming card would be much easier lol.
Yeah I drilled a little hole for mine, theres no one pre drilled because theres 3 different spots you can put the antennae tube if you wanna move it around.
The range is good for me, I don't think tucking it in will really affect it, but I've never tested it, I know I have been able to drive it far enough away that at times I've almost lost sight of it lol (like going as far down my street as possible then turning around for a speed run :P) your estimation seems about right, I never really measured it myself but I've found it's been able to stay within range of where I wanna drive.
