Worse than the plastic stock ones
Junk. These things are worthless. For starters, the HPI instructions say that these are already assembled, when in fact they are not. The shocks shafts are stiff, the oring that is supposed to seal them doesn't, and after putting them together multiple times, they continue to leak out the top. Save your money and buy something that works like it should. Never again will I buy HPI "upgrade" parts.

Not a good book for intro level STAT courses.
Its way too overpriced (but then again when are college books not). The reading is just OK at most. It assumes you already know some background in statistics - so its not good for a beginner or someone trying to learn it without a professor. The problem sets do test what was covered, but there are NO examples at all on how to do the problems, so what good is that?? Bottom line - if you need this book for a college course, get it used, keep in good condition, then re-sell because its not worth using a reference.

Awesome little motor!!
1 of 1 found this helpful I bought the Sidewinder SCT combo paired with the Castle 3800KV motor for my 1/10 scale 2WD truck - lets just say - this thing is amazing. The previous motor and ESC I had was a 3500 KV Hobbystar, and it died after only 2 months and barely any usage. I replaced it with this combo, and I couldnt be any more than happy. Installation was easy, calibration was easy, and it delivers more than enough power - instant and long standing wheelies just on 2S. I haven't even tweaked any of the motor settings either, just using the stock defaults for now. I cant wait to stick a 3S in there and see what happens.
Ive only run about 3 batteries through the ESC and motor so far, but each time it ran well. Little to no cogging that I can hear, and seems to run reasonably cool as well (though that could be because I am using stock gearing and 2S only at this point)
When I need to buy any brushless ESCs or motors for any of my other vehicles in the future, Castle motors and ESCs will be my first choice!!
