I did not read all the replies, so sorry if this is repeated.

A while back they stopped shipping the PBS or even the PCR edition (is jus tthe PBS with laydown servos) with the purple head and shipped the black head instead with pull start. It is a Hyper 21 8 port with pull start. Extremely powerful motor. They did this because the amount of complaints they had with the cheap starter box they ship with the buggy. It is not able to turn the motor over until after break in.

Hope that helps! They just never updated the website with this. When dagass got his PBS he emailed me asking if mine came with black or purple head. This was months and months ago they started this. Mine was one with purple head and no pull start. After what I went through to break the damn thing in I wish it came with a pull start.
